A_number for I-485?? Help,Please2005-09-22 05:18:15

What is the A_number to fill in the I-485 form? I got the same A-number from both OPT and H1 VISA approval notice. Can I use this A_number for I-485 or other forms asking for A-number?
Is that possible that INS assign different A-number to different cases, even the same person.

Thanks a lot.

That's the one, use that.

I have never heard that
