i-130 approval notice question laomaoshi2004-02-29 05:00:14

I-130 approval notice question:

My I-130 approval notice arrived, but it does not contain a A#(alien registration number) or the so called immigration visa number.

When I fill in the form of I-485, it asked me for this A#, but I don't have any. Should I wait for INS to send me a new approval notice for that alien registration number?

Thanks a lot.

Sincerely,
