I filled two I-140 and I-485. My A number: one is A09+7digit. The other is A9+7 digit. Except 0, other numbers are exactly the same. My question is: Do I have one A number or have two A number? In other words, is this situation called one A number or two A number? Please let me know how to handle this. Do I need to contack TSC about it? ( My case is at TSC).
I greatly appreciate your help.
