What Is An Alien Registration Number And What Is It For?

The U.S. Alien Registration Number, commonly abbreviated as an A-Number, is a unique identifier assigned to non-citizens by the United States Citizenship and Immigration Services (“USCIS”). This A-Number begins with the letter “A” followed by 8 or 9 numbers (such as A012345678).  It is used to track individuals throughout their interactions with U.S. immigration authorities.

Who Has a U.S. Alien Registration Number?

Anyone who is not a U.S. citizen but resides in the United States may be assigned an Alien Registration Number. This includes lawful permanent residents (green card holders), individuals on temporary visas, refugees, and asylum seekers. Even individuals who are in the U.S. without legal authorization may have an A-Number if they have had interactions with immigration authorities or if they are in proceedings to determine their immigration status.

What is the U.S. Alien Registration Number it used for?

  1. Identification: The primary purpose of the U.S. Alien Registration Number is to uniquely identify non-citizens in various interactions with U.S. government agencies, particularly those related to immigration and residency.
  2. Immigration Proceedings: A-Numbers are used extensively in immigration proceedings, including applications for green cards, asylum, and citizenship. They help immigration officials track individuals’ histories, applications, and statuses within the complex immigration system.
  3. Employment Authorization: Non-citizens who are authorized to work in the United States typically need to provide their Alien Registration Numbers to their employers for verification purposes, although the A-Number is not, on its own, evidence of work authorization.
  4. Taxation: A-Numbers may also be used for tax purposes, particularly for non-citizens who are required to file U.S. tax returns. This helps the Internal Revenue Service track tax liabilities and contributions.
  5. Law Enforcement: In some cases, law enforcement agencies may use A-Numbers to identify and track individuals who are involved in legal proceedings or criminal activities.

How to Find Your U.S. Alien Registration Number

If you are unsure whether you have a U.S. Alien Registration Number or need to locate it, there are several ways to do so:

  • Immigration Documents: Your Alien Registration Number may be listed on various immigration documents, such as your green card, employment authorization card (EAD), or notices from USCIS.
  • Correspondence from USCIS: Any official correspondence you have received from USCIS regarding your immigration status or applications will likely include your Alien Registration Number.
  • Contact USCIS: If you still can’t find your A-Number, you can contact USCIS directly for assistance. Be prepared to provide personal information to verify your identity.

The U.S. Alien Registration Number plays a vital role in the immigration process for non-citizens residing in the United States. From identification to immigration proceedings and beyond, this unique identifier is essential for navigating the complex legal and administrative landscape of U.S. immigration law. Understanding its significance can help individuals better manage their immigration statuses and interactions with government agencies.

DHS to Begin Screening Foreign Nationals Social Media Activity for Antisemetism

Effective immediately, the United States Department of Homeland Security (“DHS”) will begin considering a foreign national’s antisemetic activity on social media and the physical harassment of Jewish individuals as grounds for denying immigration benefits. The new policy, which is consistent with President Donald Trump’s Executive Orders on Combatting Antisemetism, Additional Measures to Combat Antisemitism and Protecting the United States from Foreign Terrorists and Other National Security and Public Safety Threats; will apply to foreign nationals applying for an adjustment of status, foreign students on F-1 and M-1 student visas and those affiliated with educational institutions linked to antisemetic activity. The United States Department of State provides a working definition of antisemitism as “certain perception of Jews, which may be expressed as hatred towards Jews. Rhetorical and physical manifestation of antisemitism are directed toward Jewish or non-Jewish individuals and/or their property, toward Jewish community institutions or religious facilities.” Under the new

Trump Administration Issues Executive Order Requiring Alien Registration Requirement

As posted on the United States Citizenship and Immigration Services (“USCIS”) website, on January 20, 2025, President Trump issued Executive Order (“EO”) 14159, “Protecting the American People Against Invasion”. The EO directs the Department of Homeland Security (“DHS”) to ensure that aliens comply with their duty to register with the government.  Failure to comply with the registration requirement is treated as a civil and criminal enforcement priority. The DHS  requires that, with limited exceptions, all aliens 14 years of age or older who were not registered and fingerprinted (if required) when applying for a U.S. visa, and who remain in the United States for 30 days or longer, must apply for registration and fingerprinting. Similarly, parents and legal guardians of aliens below the age of 14 must ensure that those child aliens are registered. Within 30 days of reaching his or her 14th birthday, all previously registered aliens must apply for re-registration

CDC Removes COVID-19 Vaccination Requirement for Immigrant Visa Applicants

Effective March 11, 2025, The United States Center for Disease Control (“CDC”) has removed from the technical instructions to panel physicians the requirement that immigrant visa applicants receive the COVID-19 vaccination.  Panel physicians will no longer determine that an immigrant visa applicant is ineligible for travel based on their failure to receive, or otherwise document, their vaccination against COVID-19. Based on CDC’s updated guidance to panel physicians, which is inline with the recent United States Citizenship and Immigration Services policy,  Embassies and Consulates will no longer refuse an immigrant visa application for failure to present documentation that they received the COVID-19 vaccination.  Applicants whose medical exams are unexpired and otherwise still valid for travel to the United States, and whom a consular officer previously found ineligible based solely on the applicant’s failure to establish vaccination against COVID-19, may have a new medical exam issued by the panel physician without a
