Instructions
1
Find your Certificate of Naturalization, which was issued to you by USCIS when you completed your oath of citizenship.

2
Locate your U.S. citizenship number, which appears directly above the word "Naturalization" in the top right-hand corner of your Certificate of Naturalization. Your U.S. citizenship number is the 8-digit number printed in red ink.

3
Write down your U.S. citizenship number in a safe place. You may provide this number on any document where proof of citizenship status is required.

Also, knowing this number can be very beneficial if you ever lose your original Certificate of Naturalization and need a replacement, because it will better assist USCIS in locating your naturalization record.

I gave you more information in your other question. We are a pretty basic general question and answer forum. I do not know a lot about immigration. Seems to me if you have a son in the military, you should have searched out all this information long ago. You are going to have to contact your nearest immigration agency and see what they can find about your family.
