naturalization number on certificate
I have a question: I recently got my US Citizenship and need to apply for a visa for my in-laws visiting me. While filling up the I-134, there is a question. If a United States citizen through naturalization, give certificate of naturalization number. Now, I see my Certificate of Naturalization and see 2 numbers. One is No:XXXXX and other one says CIS Registration No: AXXXXX.
