Couple requesting a copy of her immigration file from USCIS

The U.S. government’s Freedom of Information Act (FOIA) allows people to gain access to information held by the government. This right extends to immigration. You can obtain copies of the records and documents in your alien file (immigration file). As a U.S. citizen or permanent resident, you may also request the immigration records of other people (provided that person consents to the search).

You may obtain specific documents inside your records or even a complete copy of your entire immigration file. These records may be helpful to people with a pending case or even families searching for a relative’s immigration history.

What is an Alien File?
An alien file, commonly known as an A-file, is the collection of documents that the Department of Homeland Security (DHS) maintains for non-citizens. It typically contains all of the official files related to immigration status, citizenship, or relief, and includes both documents submitted by the non-citizen as well as any investigations, statements, correspondence, and memoranda created by the agencies. It also may include other identifying documents, such as birth certificates.

Reasons to File a FOIA Request

Filing a FOIA request is a great way to understand what USCIS knows about you. That’s why immigration attorneys regularly use a FOIA request to collect information about their clients’ immigration history. Attorneys want to get all available information so that they can provide informed advice. An alien file may also contain records that show approval on an immigration status.

The FOIA request is also a great way to get information about your family genealogy. You can gather actual records filed by a family member that immigrated to the United States many years ago.

An individual may file a FOIA request to:

  • Request his or her own immigration records
  • Request immigration records of another person (with that person’s consent)
  • Correct or amend these records

Obtaining an Immigration File for an Existing Case

This is a great way for immigrants to obtain a complete file of documents if you’ve lost some of the important papers provided by U.S. Citizenship and Immigration Services (or former INS). FOIA provides mandatory access to your own A-file. FOIA requests can be a very valuable tool when an applicant’s history matters to the success of an application, such as in seeking naturalization. This right even extends to individuals where removability from the United States is in process. For example, it might be necessary to see what evidence the government holds for an individual in removal proceedings. See Dent v. Holder.

Obtaining an Immigration File to Document Family Genealogy

Using a FOIA request to obtain an immigration file is also a fantastic way for families to gather genealogical information about family history. Family members can obtain copies of the immigration documents that name a great grandparent when he or she initially migrated from their country of birth. By capturing the precious details, people can get a deeper understanding of their family history.

The USCIS Genealogy Program can make five types of agency’s historical records available to aid your genealogy search:

Naturalization Certificate Files (C-Files), September 27, 1906 to March 31, 1956
