The Colombian community has a strong presence in the U.S., with many immigrants arriving each year to visit, live, study, and work.
Staying in touch with family across borders matters. That’s why it’s useful to know the different ways to make international calls from the U.S. While it can seem tricky, it’s easy if you have the right codes.
If you want to call loved ones back home in Colombia, below you’ll find step-by-step dialing instructions from the U.S., examples, and a full area-code table.
Before calling anyone in Colombia, know the sequence: international prefix + country code + local number.
This is the international prefix from a landline. If you’re using a mobile phone, use the “+” sign instead.
This identifies Colombia in the international telephone system.
For landlines include the city area code. For mobile phones, dial the full 10-digit mobile number.
Examples:
There’s a difference between calling a landline and a mobile in Colombia from the U.S.: landlines need the regional area code; mobiles are dialed using the “+” format on cell phones.
Below you’ll find the area codes for Colombia’s main cities to ensure you dial correctly when contacting your family.

The phone is a favorite way to bridge distances and stay in touch with loved ones across borders.
Years ago, international rates were expensive, making frequent calls home difficult.
Today, digital options have lowered costs and made cross-border communication much easier.
Below we show some affordable options to help you stay in touch with the people who matter most.
Mobile apps are hugely popular worldwide. They enable texting, voice notes, and voice/video calls over Wi-Fi or data—significantly cutting costs.
WhatsApp is the most popular, and other solid options include FaceTime, Google Voice, and Skype.
If you prefer traditional calling, look for an international plan from your U.S. provider with minutes to Colombia—great for frequent calls.
You can pick plans with minutes to landlines and mobiles or Colombia-specific bundles.
Examples of U.S. carriers include AT&T Prepaid, T-Mobile, Verizon, and Ultra Mobile. Options range from unlimited international add-ons and prepaid plans with international calling to limited-minutes bundles and mixed data/calling packages.
If you’re in the U.S. for only days or weeks, a mobile plan may be overkill. A prepaid calling card can be ideal—no PINs in many cases and you only pay for the minutes you use.
As you’ve seen, calling Colombia from the U.S. is straightforward—just use the correct codes. You can also choose affordable alternatives like mobile apps or prepaid cards.
Staying in touch shows care and support. It also helps to have accessible services to send money and support their well-being.

If you don’t dial 011 from a landline or “+” on mobile, your call won’t be recognized as international and will fail as a local call.
There are several affordable options—apps like WhatsApp, Skype, or Google Voice; prepaid calling cards; or an unlimited international plan. The best choice depends on your habits and how often you call.
Costs vary by method. For example, AT&T offers unlimited add-ons around $15/month and Verizon offers 300 minutes for about $10/month.
Conclusion
Starting a business as an immigrant is entirely possible with the right steps. By choosing the right business structure, obtaining the necessary tax IDs, and registering properly, you’ll build a strong foundation for success.

In today’s digital era, having access to technology that enables fast and secure money transfers is essential.
Zelle is a service that allows easy transactions, as it is integrated into the digital banking platforms of U.S. banks.
Without a doubt, Zelle is one of the most popular digital payment services in the United States. According to recent data, in 2024 the company processed more than $1 trillion across over 3.6 billion transactions.
Additionally, 151 million user and small business accounts are registered with Zelle, representing a growth of 16 million compared to 2023.
If you need to send or receive money, this could be an excellent option, since all you need is a mobile phone number or email address.
It is also integrated with major U.S. banks, such as Bank of America and Wells Fargo.
It is essential to know the list of banks that offer Zelle in the United States to ensure that you will be able to use the service through your bank—especially as new conditions came into effect in April 2025.
For this reason, we will explain in detail what Zelle is in the U.S., the main banks that support the service, and how it works.
According to Denise Leonhard, CEO of Zelle, this company is not just a popular way to send money; it is a vital tool transforming the way money moves in the United States.
Zelle is a network developed by Early Warning Services, LLC, which allows digital payments and bank transfers between users of the same or different banks, mainly within the U.S.
It is directly integrated into banking apps, making it easier to manage transactions within the same mobile banking experience.
Zelle offers multiple benefits for its users, such as:
Transfers are completed in minutes
Transfer service is free at most financial institutions
No external app is required, as Zelle is integrated into bank apps
You only need the recipient’s email or phone number to send money
Available through a large number of U.S. banks and credit unions
Uses funds directly from your bank account; no need to top up a digital wallet
This service is an excellent option if you are looking to make fast, secure, and free transfers within the U.S., although it does not support international money transfers.
Zelle’s presence in daily financial operations has grown significantly. According to recent data, Zelle is integrated with more than 2,200 U.S. banks, 95% of which are community banks and credit unions.
Below is a list of major financial institutions using Zelle in 2025 and their transfer limit if applicable. Please refer to each financial institutions for the most up-to-date information
| Name | Transfer limit |
|---|---|
| TRADITIONAL FINANCIAL INSTITUTIONS | |
| Bank of America | 3,500 USD per day |
| Chase | Dynamic limit set by the institution. Ranges from 500 to 10,000 USD per day |
| Citi Bank | 2,500 USD for accounts registered more than 30 days ago |
| TD Bank | 1,000 USD for instant transfers and 2,500 USD for scheduled transfers (up to 3 business days) |

To use Zelle through these financial institutions, there is no need to download a third-party app, as all have direct integration. Additionally, transfers are free of charge.
To receive money using Zelle, follow these steps:
Note: To send and receive money through Zelle, both parties must have accounts at banks that support the service.
If you want to use Zelle and are unsure whether your bank supports it, visit Zelle’s official website and enter your bank’s name in the search bar. If it appears, you can use Zelle via your mobile banking app.
Integration with Zelle offers banks several advantages:
Zelle provides an edge over services like Venmo and PayPal, and encourages mobile banking app usage.
Zelle simplifies person-to-person transfers and consolidates transaction history in one place.
P2P transfers are more cost-effective than traditional payment methods like checks.
Encourages more frequent use of the banking app and reduces customer churn.
Backed by official U.S. financial institutions, Zelle adheres to strict banking and regulatory standards.
Zelle enables quick transfers, even between different banks.
With over 2,200 integrated banks, Zelle is a leading digital payments system, prompting other banks to join.
Zelle recently announced changes effective April 1. As of that date, users can no longer send or receive money through the standalone Zelle app.
Users of the standalone app must now re-register through their bank’s online platform, provided the bank is integrated with Zelle.
If you do not have a bank account linked to Zelle, you will no longer be able to use the service. It is essential to review Zelle’s FAQ section for the latest updates and list of participating banks.
Important Security Tip:
Always verify the recipient’s information, as Zelle does not offer fraud or error protection. Once money is sent, the transaction cannot be canceled.
If your account is not with a Zelle-integrated bank, or if you used the standalone Zelle mobile app and don’t have a bank account, there is a solution designed for you that simplifies transfers and financial inclusion in the U.S.
Comun offers an easy, accessible, and affordable alternative for making transfers and payments.
It is a platform that promotes financial inclusion for individuals facing barriers with traditional
U.S. banks, offering a user-friendly, Spanish-language service. Some key benefits of Comun include:
Open your Comun account and start your financial life without complications.

Comun no tiene sucursales, pero cuenta con un equipo que apoya a sus clientes las 24 horas del día, los 7 días de la semana, sin salir de sus hogares, en tres idiomas diferentes.
Construir mejor futuro para los inmigrantes en los EE. UU. es un principio fundamental de la misión de Comun. Opciones bancarias accesibles y fáciles de entender son una parte clave del viaje del inmigrante. Sin embargo, las opciones son escasas.
Las opciones complejas, engorrosas y costosas son la norma. Actividades que pueden parecer triviales e intuitivas para los nacidos en los EE. UU. son abrumadoras y confusas para un inmigrante recién llegado. Todo, desde configurar un depósito directo con un empleador hasta enviar dinero a casa, realizar pagos de bienes y servicios o comprender cómo construir un puntaje crediticio, parece demasiado complejo para cualquiera que nunca haya tenido que hacer esto en los EE. UU., y mucho menos en absoluto.
Las tarifas ocultas y las comisiones costosas añaden un nivel de estrés al comenzar una vida financiera en los EE. UU. Entre los saldos mínimos de cuenta, las tarifas mensuales, los cargos por sobregiro, las grandes tarifas de depósito de cheques, las comisiones extorsivas de transferencias internacionales y todo lo demás, mantener y usar una cuenta bancaria en los EE. UU. puede ser costoso. Para los trabajadores manuales, esto puede representar un porcentaje importante de su salario.
Las ubicaciones físicas de los bancos tradicionales también pueden ser escasas en algunas áreas. Dado que abrir una cuenta bancaria o depositar un cheque o efectivo en la cuenta debe hacerse en la sucursal, esto es una carga significativa para alguien que vive en una zona remota. Muchos inmigrantes, a veces trabajando en granjas o fábricas remotas, viven en áreas a kilómetros de distancia de la sucursal bancaria más cercana. Los costos de transporte a esas sucursales se suman a las tarifas ya altas de usar y mantener una cuenta.
Incluso si los servicios bancarios proporcionados fueran más intuitivos, digitales y a un costo menor, queda otra barrera importante. Obtener la documentación necesaria para abrir una cuenta bancaria también puede dificultar el acceso a servicios financieros justos y simples. Los inmigrantes lo suficientemente afortunados como para tener autorización de trabajo aún necesitan reunir documentación importante que no siempre está disponible para ellos. Para aquellos que han llegado a los EE. UU. buscando asilo o mejores oportunidades de trabajo siguiendo un camino más no convencional, los documentos requeridos para abrir una cuenta a menudo son prohibitivos.
Construir una plataforma bancaria 100% digital para resolver los problemas mencionados es parte de lo que Comun busca lograr porque creemos en ayudar a desbloquear la movilidad social. Pero una plataforma digital, de bajo costo e intuitiva no es suficiente. Para navegar este proceso, los inmigrantes necesitan ayuda, y la ayuda se encuentra mejor en una Comunidad que los entiende cuando más lo necesitan.
Es por eso que no solo nuestros clientes son parte de nuestra Comunidad, sino también las personas que los ayudan las 24 horas del día, los 7 días de la semana a través de nuestra aplicación, redes sociales, WhatsApp o por teléfono. Más allá de resolver un problema inmediato, el apoyo brindado va más allá. Enseña y educa, empatiza y se esfuerza por fomentar un sentido de Comunidad de personas que los entienden, en términos que comprenden y en el idioma que hablan. Este es el núcleo de la verdadera banca comunitaria digital. Nuestro equipo les ayuda a configurar su depósito directo, conectarse a Zelle, obtener reembolsos por cargos con los que no están de acuerdo y todo lo demás.
En Comun, el primer paso en este viaje ha comenzado. Nuestro equipo en Mérida, México, es parte de nuestra Comunidad y a la que buscamos servir. Son una extensión de nuestra misión y de nuestra plataforma digital, y un ingrediente necesario para desbloquear la movilidad social para millones de inmigrantes en los EE. UU.

Immigration

Finding a path that gives you job opportunities in the United States can be hard work, especially if you’re unfamiliar with the different visa types offered by the U.S. government.
The H-1B visa is an option that could open the door to a new life in the U.S. In this guide, we explain what it is, what it’s for, who can apply, when it applies, and its benefits and limitations.
It’s essential to understand this visa’s features—as well as how it differs from other work visas—so you can ensure it fits your professional goals in the country.
With this information, you’ll be able to plan a strategy to obtain the visa and fully establish yourself in the United States.
The H-1B visa is authorization granted to foreign workers to temporarily perform specialty occupations that generally require specialized knowledge and prior experience.
It is a nonimmigrant visa with an initial duration of 3 years and, in most cases, can be extended up to a maximum of 6 years.
There are exceptions, such as when the temporary worker is in the process of obtaining permanent residence, in which case the visa may be extended for a longer period.
Before starting the immigration process, you should know the H-1B requirements and verify that your background aligns with them to determine eligibility.
To obtain an H-1B visa, you must have a higher education degree or its U.S. equivalent. The job offer must also be related to the specialty area of the degree presented.
As with the EB-3 visa, the H-1B also requires a job offer from a U.S. employer, who must file Form I-129 with USCIS.
Keep in mind that this visa is used for jobs requiring specialized knowledge, and openings most often arise in the following areas:
Another key point is that this visa has an annual issuance cap, divided as follows:
Because filings often exceed these limits, USCIS established a selection system consisting of electronic registration and a random lottery.
The draw occurs in two phases: first the 65,000 regular slots are selected, and then 20,000 additional slots are drawn for U.S. advanced degree holders.
Between March and April, employers receive notification of the lottery results. If not selected, you may wait for a second round if quotas aren’t filled or, otherwise, apply the following year.
Below is how the H-1B application process works.
First, the U.S. employer must register the candidate on USCIS’s official site during the designated window, generally in March. The registration fee—listed on the same site—must also be paid.
If the candidate is selected, the employer receives a USCIS notice and can proceed to the next stage.
Note that before filing with USCIS, the employer must obtain a certified Labor Condition Application (LCA) from the Department of Labor (DOL).
After selection, the employer has 90 days to file Form I-129, Petition for a Nonimmigrant Worker, along with required documentation.
At this stage, it’s necessary to show the position is a specialty occupation and that the candidate meets the requirements.
USCIS reviews the filing and, if needed, issues a Request for Evidence to seek additional information or clarification.
If everything is in order, the employer receives an approval notice, and the candidate proceeds with consular processing or a change-of-status request.
If the candidate is outside the U.S., they must attend a U.S. consulate, complete Form DS-160, and appear for a consular interview.
If the candidate is already in the U.S. under another status, the employer files the H-1B petition indicating the worker is in the United States.
In both cases, USCIS approval is required before visa issuance can proceed.
H-1B holders enjoy several benefits that can improve their lives and those of their families; however, it’s also important to note the limitations.
Although temporary, the H-1B allows you to work legally in the United States in your field of specialty. This can open many doors and strengthen your professional experience.
H-1B workers may later pursue permanent residence (a Green Card) and extend benefits to immediate family members such as a spouse and unmarried children under 21.
As noted, this visa does not automatically confer permanent residence; it lasts a maximum of 6 years. Still, it can be a first step toward it.
This visa depends entirely on the employer extending the job offer and completing the filing process.
The visa is numerically capped, and filings typically exceed the annual cap, reducing the likelihood of selection.
To prevent these limits from becoming obstacles, consider planning ahead if you intend to pursue permanent residence. You can also evaluate other work visas, such as EB-2 and EB-3, which may be more suitable for long-term plans in the United States.
Here we covered how to file for the H-1B visa, the requirements, benefits, limitations, and who it’s ideal for.
When you arrive in the United States, you’ll need an ally to help you manage your finances easily. Meet Común!
Open your Común account today and manage your money in the U.S.
Your employer must sponsor permanent residence under an employment-based category, file PERM with the DOL, and then file Form I-140.
A maximum of 6 years.
Form I-129: from $460 to $780.
An anti-fraud fee may apply.

Have you heard of Venmo? It is a digital payment application that has gained popularity in the United States in recent years. According to recent data, in 2024 the mobile application reached 68.3 million active users, representing an 8.8% increase compared to 2023.
The importance this mobile application has acquired cannot be denied, which is why knowing what Venmo is in the United States can be very useful to send and receive money from family and friends quickly and securely.
As a foreign national living in the U.S., you must ensure that you choose a financial platform that meets your needs for sending money to your home country and making payments with ease.
In this guide, we clarify all your potential questions about how to use Venmo in other languages like Spanish, what it is for, the requirements to open an account, the benefits this mobile app offers, and also its limitations.
Venmo is a highly popular P2P (peer-to-peer) payment mobile application in the U.S. Its primary purpose is to facilitate the instant transfer of money between friends and family, in addition to allowing users to link bank accounts and cards.
Venmo’s business model is based on charging fees for services such as credit card transactions, instant transfers of money to bank accounts, and transactions using its physical card.
Some of the most common reasons immigrants use Venmo include:
To fully understand what Venmo is in the United States, it is important to explore the functionalities this P2P payment service offers its users to simplify their lives:
Now that you know the benefits of this mobile application in detail, you probably want to learn the requirements to start using it.
Before learning how to pay with Venmo, remember that it only works in the United States.
These are the requirements to use Venmo:
To verify your account, Venmo will request the following:
To transfer money from Venmo to your bank account, once it is linked and verified, follow these steps:
1. Log into your account through the mobile app and go to the “Me” tab.
2. Press the “Transfer” or “Add” button.
3. Enter or edit the amount you want to transfer to your bank account.
4. Select the transfer method: “Instant” or “up to 3 biz days,” noting any applicable fees.
5. Confirm the transfer details and complete the process.
If you want more options for depositing money into another person’s account, do not miss these recommendations.
The need for immigrants to have an integrated solution allowing access to digital payments, transfers, and other benefits increases daily. Therefore, while Venmo is a popular option for sending and receiving money in the U.S., it may present limitations for immigrants working in the country.
One limiting factor for immigrant communities is the language barrier in customer support. Because it is a service designed for U.S. residents, it is not optimized for people who speak a different language, such as Spanish. In addition, you should have a U.S. bank account.
Your best option may be to entrust your financial assets to a service offered in your language.
We present Comun, the solution for immigrants seeking to improve the way they send and receive money to family and friends.
Why Is Comun a Great Option for Immigrant Communities in the United States?
If you think accessing quality financial services in the U.S. is impossible for immigrants, open your Comun account today and forget about complications.

Do you have children about to enter school in the United States? Understanding the U.S. education system is essential for adapting to a new culture and preparing for the differences compared with your country of origin.
Broadly speaking, the U.S. education system is divided into three stages: Elementary School, Middle School, and High School. Each plays a specific role in students’ academic journey. This system covers ages 5 through 18 and forms the central framework of schooling in the country.
In this article, we explain each of these stages and detail their purpose to demystify how students progress through the system and its educational levels in the United States.
In the United States, it is common for children to begin schooling around age 5. After kindergarten, it is divided into 12 grade levels.
Below, we show how the U.S. education system is structured.
Early childhood education or preschool is not mandatory in the United States. However, it is common for children under age 5 to attend pre-K (preschool) or kindergarten.
These centers focus on young children’s cognitive development through play and early literacy activities. For this reason, there is no grading system. Kindergarten is offered through private and public options or via the Head Start social assistance program for low-income families.
After that, children will enter primary education or Elementary school starting around age 6, depending on the school district.
This level typically covers 1st through 5th grade and is characterized by the gradual introduction of more advanced knowledge, with the aim of building cognitive and social development through learning skills such as mathematics, science, and language, among others.
After finishing primary education, students continue with Middle school, which typically covers 6th through 8th grade. It is a transitional stage between primary and secondary education.
The next level is secondary school or High school, typically covering grades 9 through 12. It culminates in the High school diploma, a basic requirement to continue with higher education or enter the job market.
Postsecondary or higher education in the United States includes different types of programs as well as private and public schools. Although it is not strictly mandatory, it provides more opportunities for good jobs and higher earnings.
These are the types of higher-education institutions in the U.S.
If you need to send money to another country, explore some options and tips.
The U.S. education system can be somewhat confusing compared with other countries, such as some in Latin America. Below is a comparison table to clarify general equivalencies, keeping in mind that there are variations in each country.
| Grade level in the United States | Typical Ages | Equivalence in Mexico |
|---|---|---|
| Preschool | 3–4 years | Preschool/kindergarten |
| Kindergarten | 5–6 years | Final year of preschool |
| 1st grade | 6–7 years | 1st year of elementary |
| 2nd grade | 7–8 years | 2nd year of elementary |
| 3rd grade | 8–9 years | 3rd year of elementary |
| 4th grade | 9–10 years | 4th year of elementary |
| 5th grade | 10–11 years | 5th year of elementary |
| 6th grade | 11–12 years | 6th year of elementary (start of Middle school in some countries) |
| 7th grade | 12–13 years | 1st year of Middle school |
| 8th grade | 13–14 years | 2nd year of Middle school |
| 9th grade | 14–15 years | 3rd year of Middle school (may be the final year of secundaria or 1st year of High school) |
| 10th grade | 15–16 years | 1st year of High school |
| 11th grade | 16–17 years | 2nd year of High school |
| 12th grade | 17–18 years | 3rd year of High school |
| Postsecondary education | 18 and up | University |
The U.S. education system is characterized by flexibility to adapt to students’ abilities and interests in order to foster their full potential.
For this reason, it is common for students to be placed into specific classes according to their learning level, which may be more or less challenging.
Another relevant aspect to consider is the school calendar and schedule in the United States. These can vary by state and school district, but in general the school year begins in late August or early September and ends in late May or early June.
As you can see, the U.S. education system is intentionally designed to guide students from basic education through higher studies and, afterward, into working life.
Each level has a clear function, which makes it easier for families, students, and educators to plan and provide support in order to make more informed decisions along the school path.
Without a doubt, your children’s education is one of the most important investments, because it is a way to secure their future.
Común is the ideal financial platform to help you manage tuition payments and handle school expenses for higher education.

How do you enroll your child in school?
Go to the school district where you live to find out which school corresponds to your address. Complete the required documents and the enrollment application.
Requirements may vary by state or school district, so it is important to verify directly with your local school.
Public schools are funded by government tax revenues, while private schools are funded by tuition.
These are the terms used in U.S. high schools and universities to indicate year level

International Money Transfers

If you need to send money to your home country from the United States, it is important to consider how long an international money transfer takes. In general, the processing time for this type of operation is usually 1 to 5 business days.
However, this depends on several factors, such as the payment system, the banks involved, the currency conversion, and the holidays in between.
That is why it is important to know the different types of international money transfers available, the advantages and disadvantages of each one, and, of course, how long they take to deliver the money to its destination.
Below, we offer you a guide to answer those questions so you can send money home as quickly and safely as possible.
First of all, an international transfer is the sending of money to a bank entity located outside the country of the originating account. Unlike domestic transfers, international transfers involve additional banking systems, such as the SWIFT networks, which can increase costs and processing times in many cases.
There are several factors that influence the total time an international money transfer takes, but in general, it takes 1 to 5 business days.
For example, one relevant aspect that influences this is the system used, whether SWIFT or SEPA, which have different conditions and characteristics.
The SWIFT system is the largest network: it connects thousands of traditional banks worldwide to send money from one country to another through secure mechanisms.
Characteristics of the SWIFT system
On the other hand, the SEPA system is focused on international money transfers within the European Union.
As you can see, both the SWIFT and SEPA systems are useful for making international money transfers safely. Although for those living in the United States, the latter is not recommended due to its geographic limitations.
Here is a comparison table:
| SWIFT | SEPA | |
|---|---|---|
| Time | 3 to 5 business days | 1 business day |
| Cost | Expensive, due to the involvement of intermediaries | Affordable |
| Geographic availability | Worldwide | Exclusively in Europe |
The time an international money transfer takes is not fixed. It varies according to the type of transfer and other elements involved in the operation.
Here is what you need to know to estimate how long it will take for your money to reach your loved ones.
So far, we have presented the SWIFT system, which takes 3 to 5 business days, and SEPA, which is generally reflected the next business day.
In addition, there are ACH (Automated Clearing House) transfers, which are a more common system in the U.S., characterized by being a more economical option, although the process usually takes 2 to 3 business days.
There are cases in which the financial institutions participating in an international money transfer do not have a direct relationship with each other, so they need to involve intermediary banks. This, in addition to increasing costs, lengthens transfer times, because it makes the operation take longer than usual.
Another essential aspect is the cut-off time banks have for executing transactions. If you send money after this time, the operation is processed the next business day.
Also, do not forget to take into account the holidays of both the sending country and the receiving country, which also extend the waiting time.
When sending money from the United States to your home country in Latin America, the bank will need to make the corresponding currency exchange and apply an exchange rate. This also usually adds time to the international money transfer process.
Banks often carry out security checks to prevent money laundering and fraud, especially when large amounts are involved.
You are almost ready to start sending money abroad. But first, it is very important that you make sure you have the necessary information to process this type of transfer. Otherwise, the transfer could be rejected or take longer than usual.
You will need to provide your basic personal information: full name, bank account, official address, and phone number.
It is also essential to provide the details of the person who will receive the money: full name, recipient’s account number, address, and country of origin.
Indicate the amount of the transfer and the currency in which it will be received.
Finally, indicate the purpose of the transfer. It may be: maintenance payment, family support, family savings, etc.
We know that sending money to your family and loved ones is very important, which is why it is vital that you avoid mistakes and bad practices that could delay your transfers even more.
This time, we learned that international transfers are money transfers made from one country to another, and there are several factors involved in the time they take to be completed.

If you need to make bank transfers in the United States, it will be useful to know what the ACH network is and understand its importance in the country’s banking system.
ACH (Automated Clearing House) is an Automated Clearing House that handles the processing of electronic transfers between U.S. accounts.
It is highly relevant for receiving direct payroll deposits, also known as ACH credits, and for processing recurring payments, due to several advantages compared to the traditional bank network, such as cost reduction and traceability of operations.
According to official sources, in 2024 the ACH payment network processed around 33.6 billion electronic payments, with a value close to $86.2 trillion, underscoring the importance of this method in the U.S. financial system.
On this occasion, we will explain in detail the advantages of this type of transaction and provide some recommendations so you can get the most out of them.
ACH or Automated Clearing House is a network that allows money to move between banks, credit unions, and other financial institutions in the United States, where the use of cash or checks is not necessary, because everything is processed electronically.
The central part of this system is NACHA (National Automated Clearing House Association), which oversees compliance with the rules and ensures transfers are carried out according to established security standards.
It is very likely that in your daily life you have already used the ACH system without noticing it. For example, for:
In the United States, there are different systems for moving money. In addition to the ACH network, you can rely on more traditional networks such as wire transfers and checks.
The main difference with other bank transfer systems is that ACH focuses on electronic, secure, and low-cost payments, which take longer than other options that tend to be more expensive; whereas ACH transfers are more suitable for recurring payments and direct deposits.
Below, we show you a comparative table so you can visualize the fundamental differences between ACH payments and other methods.
| ACH | Wire transfer | Check | |
|---|---|---|---|
| Transaction speed | From 1 to 2 business days | From minutes to hours | From 2 to 5 business days |
| Cost per transaction | Free or reduced | Variable, around $25 to $50 USD | There may be issuance costs |
| Geographic availability | Only within the United States | National and international | National and sometimes international |
| Most common use | Payroll payments, bills, transfers between accounts, automatic payments | Transfers of large amounts of urgent money | Traditional payments between people without access to a bank account |
One of the main advantages of ACH payments is the security involved in using this system to transfer money. This is because it is regulated by an organization called NACHA, which verifies each transaction based on financial system regulations, thereby reducing the chances of fraud.
Despite the trust that ACH transfers provide, they also present some limitations.
These are the most common benefits and limitations of the ACH system:
If you need an alternative for making recurring payments and direct deposits to a bank account within the United States, the ACH network is a popular alternative due to its security standards and accessibility. But if you are looking for other types of financial services, you can consider more comprehensive options.
As you can see, ACH payments are a reliable option for making and receiving money transfers, as long as they are scheduled transactions within the United States and within the limits set by banks.
It is very important to have a reliable and transparent partner to move your money and manage your personal finances in a comprehensive and efficient way.

If you have questions about what ACH is and what it is for, consult our Frequently Asked Questions section.
Generally, ACH transfers take 1 to 2 business days. It is also possible they are completed the same day if the bank offers the same-day ACH option.
ACH transfers are usually free up to the applicable limits. Some banks charge a minimal fee, around $3 USD. It is a more economical option than a wire transfer, which can cost more than $50 USD.
Yes, ACH transfers are regulated by the NACHA system, so they are easily traceable and protected with anti-fraud security measures.
No, to send money through the ACH system you need an account number from a U.S. bank or credit union. Otherwise, you can resort to more accessible alternatives such as Venmo, PayPal, and Común.
An ACH payment is a money transfer processed through the ACH system and managed by NACHA (National Automated Clearinghouse Association).

Immigration procedures in the United States are often exhausting and confusing because of the number of requirements and the associated wait times.
You don’t have to feel alone during these processes: you can rely on a recommendation letter, which gathers family, community, or workplace support from people who truly trust your integrity and are willing to offer genuine backing that could bear on USCIS’s final decision.
Below is a user-friendly, practical guide on how to write an immigration recommendation letter, what it should include, mistakes to avoid, sample letters, and tips to convey credibility and improve your chances in a visa or Green Card process.
A recommendation letter is a personal document that supports U.S. immigration processes and is valued by USCIS. It serves as testimonial evidence of the applicant’s moral character, work ethic, and community contribution.
This supporting letter may be requested to complement documentation for various proceedings:
Applicants commonly must show “good moral character,” employment stability, and community ties.
The letter helps reinforce the applicant’s credibility and show they have support in the United States as a contributing community member.
Professionals or researchers often need a recommendation letter from expert peers to substantiate their track record and expertise.
Recommendation letters are not always requested, but they can support evidence of the applicant’s good conduct.
Don’t confuse this with an employment or academic letter; the purpose of an immigration recommendation letter is to attest to the applicant’s good behavior and moral character.
An immigration recommendation letter should be written by someone with a genuine, close relationship to the applicant who can attest to their positive impact—through family, social, or workplace ties.
These are the main profiles you can ask for a recommendation letter:
They can testify to the applicant’s role in the family and commitment to loved ones.
A close friend can focus on qualities like loyalty, honesty, and trustworthiness to emphasize the applicant’s human side.
They provide key testimony of the applicant’s work ethic and professional responsibility.
These individuals can speak to the applicant’s community involvement and positive impact.
Keep in mind that what matters most is not the recommender’s title, but their sincerity and credibility in vouching for the applicant’s reputation.
Although an immigration recommendation letter focuses on the applicant’s ethics and moral character, it is still a document evaluated for order and formality by U.S. authorities.
For that reason, be sure to include the following details.
Include the applicant’s full name, address, date, and a formal salutation to USCIS or the relevant authority.
The sender should state their full name and then explain their relationship to the applicant, how long they’ve known them, and the letter’s purpose.
This is the most important part and should reflect aspects such as:
Include concrete examples to reinforce credibility, such as: “Alicia Martínez is known in the community as someone who looks out for others’ well-being, like the times she has actively taken part in trash-collection programs and efforts to help homeless children.”
The sender should reaffirm support for the applicant and be open to being contacted to clarify any point, so contact details are necessary.
At the end, they should include their name and handwritten signature.
Below is a reference letter template to make drafting your document easier.
Sender’s full name
Address
Phone number
Date
To the attention of U.S. Citizenship and Immigration Services (USCIS):
My name is [Sender’s name], and I have known [Applicant’s name] for [number of years] through our professional relationship at [describe job title and company]. I am honored to provide my testimony in support of their U.S. immigration process.
Over the time I have known them, I have observed qualities such as punctuality in reporting to work and professionalism toward both colleagues and clients.
I am confident that [the applicant] will be a valuable member of U.S. society because of their human values and professional capabilities.
I remain at your disposal and include my contact information in case any questions arise.
[Signature][Full name]
You can use this example as a base, but you should adapt it to the relationship between you and the recommender and add any additional information to convey authenticity and sincerity. Be sure to include the introduction, qualities, examples, and a formal closing.
Here we’ve shown what an immigration support letter is and how to write one in Spanish, who can write it, its structure, and a practical example.
The main objective of a recommendation letter is to support you in U.S. immigration procedures; likewise, Común supports your financial life upon arrival in the country.

If you still have questions, see the section below:
There is no specific number. A single well-written letter may be sufficient. For extraordinary-ability visas or National Interest Waivers (NIW), more than four may be required to support the applicant’s professional record.
You can ask an immigration attorney to prepare a statement explaining why no one is available to provide a letter.
Ideally, submit the letter in English or include a certified translation to avoid issues during the visa application.
