PraetorianXI -Which 1 is Naturalization certificate number

[BBW]

PraetorianXI,

Trying to fill out an I-130 form..it asks for a Naturalization certificate number..Likely is a trivial question for most here, but I am looking at husband certificate of naturalization and for some reason I am confused as to which one is it is. Is it the 8 digit number printed in red or is it the Alien Registration number (named CIS registration number) that starts with an A?

Also for form I-130 Part B#10- asking for alien number for the petitioner, since my husband is a USC through naturalization, should i put in the his previous A# Alien Registration number (named CIS registration number)?

Thanks again!!! i really appreciate ur helpful answer.

The Certificate Number is the 8 digit one printed in red.

The Alien number is the one that starts with A.

Use each when it is required.
