Sorry for the delay. I was doing some research. It’s somewhat complicated. First, you need to find out what if anything was filed for you with immigration and how you actually entered. You can file a G-639 Freedom Of Information Act (FOIA) request and get a complete copy of your immigration file which should include the information that you seek. It is free but may take 2 to 3 months or more to process. Here is a link:
If you determine that an I-600 or I-600A was filed for you, then you most likely entered with an immigrant visa. Here is a link:
At that point, you were a U.S. Lawful Permanent Resident when you entered and you just need to file an N-600 to get a Certificate of U.S. Citizenship.
If it is determined that you entered on a B-2 tourist visa and they filed an I-130 for you, then you are still ok, but you need to file an I-485 to get Lawful Permanent Residency status. You won’t be able to get U.S. Citizenship automatically because you are over 18, but you would just have to wait a few years to apply for U.S. Citizenship.
If it is determined that you entered on a B-2 and an I-130 was not filed for you before you turned 21, then you may be in trouble and you should hire an immigration attorney to review your file and see what limited options may be available to you. You can look for one at www.ailalawyer.com.
