What You Need to Know About Your Alien Registration Number?

❯❯


What is an Alien Registration Number?

The Alien Registration Number, commonly referred to as the A-Number, is a unique identification number assigned to non-citizens by U.S. Citizenship and Immigration Services (USCIS) and its predecessor, the Immigration and Naturalization Service (INS). This seven- to nine-digit number is crucial for tracking an individual's immigration files and is essential when applying for various immigration benefits.

Where to Find Your A-Number

On USCIS Documents: Your A-Number appears on a variety of USCIS or former INS documents. It is used extensively across USCIS to track applications and petitions.

Formatting the A-Number: If your A-Number is fewer than nine digits, pad it with zeroes immediately after the 'A' to ensure it has nine digits. For instance, an A-Number like "12345678" should be formatted as "A012345678."

A-Number on a Green Card

If you are a permanent resident, your A-Number is prominently displayed on the front of your green card. Additionally, this number is also embedded within the characters on the backside of the card.

Who Doesn't Have an A-Number?

It's important to note that U.S.-born citizens do not have A-Numbers. Similarly, many nonimmigrant visitors to the United States, who enter on temporary visas for tourism, business, or short-term work, are also not assigned A-Numbers.

The Alien Registration Number is a key identifier for immigrants in the U.S. immigration system, playing a vital role in managing and accessing individual immigration records. Understanding where to find and how to format your A-Number is essential for effectively navigating the immigration process and ensuring accurate handling of your records.

Not everyone is assigned an Alien Registration Number (A-Number) by USCIS. This number is specifically created for every permanent resident, while generally, nonimmigrant visitors, such as those on B1/B2 visas for temporary visits, do not receive an A-Number. However, certain nonimmigrant classifications that receive employment authorization or other benefits may also be assigned an A-Number.

Where to Find Your A-Number

  1. On an Employment Authorization Document (EAD): If you do not have a green card but hold a work permit, your A-Number is likely listed on your Employment Authorization Document.
  2. On an Immigrant Visa: Look for your A-Number on your immigrant visa, often referred to as a visa stamp or visa foil, which is located in your passport. It is typically labeled as the “Registration Number” in the top right section of the visa.
  3. On a Notice of Action: Certain versions of the Notice of Action from USCIS may include your A-Number.
  4. On an Immigrant Data Summary: If you underwent consular processing (applying for a green card at a U.S. embassy or consulate), an Immigrant Data Summary sheet might have been attached to the front of your immigrant visa package.
  5. On an Immigrant Fee Handout: Those who applied through consular processing might also have received a USCIS Immigrant Fee handout that includes the A-Number.

Understanding where to find your A-Number is crucial for managing your interactions with USCIS, especially if you are transitioning from nonimmigrant to immigrant status, applying for work permits, or engaging in other immigration-related activities. It's important to keep track of this number as it is a key identifier in your immigration records.

I wanted to get political asylum in the United States, but I realized that it was not so easy. I was ready for the fact that I would have to collect a whole bunch of documents and answer many questions, but this did not stop me. The only obstacle for me was a complete lack of understanding where to start. I accidentally found Usa-immigrations.com on the Internet. All the information you need is there. I easily found and downloaded the form I needed, and also learned the entire list of required documents.

A very useful site for those who want to leave for America and do not know what documents need to be collected and how to arrange everything correctly. I had to face such a problem and I was able to solve it thanks to the site Usa-immigrations.com. All the information gathered here is not only useful, but also very necessary. In addition, the site staff constantly update it, so it is absolutely reliable.

It is not an easy task to issue documents to travel to the USA. Even if you know their entire list, that's not all. To obtain a visa, you must fill out the forms and if even a minor mistake is made, they will be returned to you. At Usa-immigrations.com there is more than a list of documents and forms that can be easily downloaded. Each form is accompanied by detailed instructions on how to fill it out correctly. It is very convenient. I liked the site very much, it is simple and easy to use.

I have been living in America with my family for a long time and am a citizen of this country. I decided to lure my mother to her. I began to find out what documents are needed for this. One friend advised the site Usa-immigrations.com, said that it had all the necessary information. Indeed, here I found out what documents are required. I needed to complete a Form I-130. I also found it on this site and downloaded it. Thanks to the instructions for filling it out, I was able to quickly complete everything and send the documents for consideration.
