    I have lost my Alien Registration number, and I don’t know where to find it. So I have used the Freedom of Information Act (FOIA) system to get my copy of immigration, which includes all my details, and I got my Alien Registration number.

    The Alien registered number is assigned to the person who has applied for the green card if they have any ties connected to employment, or as an asylum and refugee. Simply, it me any person who is living in the USA has an Alien registration number.

      Here are some of the possible scenarios in which you are eligible to get an alien registration number: 

      • If you are applying for work authorization in the US on an F-1 student visa, then you are eligible to apply for an A-Number. 
      • To apply for a marriage green card in the US, you will be granted an Alien Registration number once you have received the USCIS notice after filing the green card application form.
