How critical are the I20s to I485? I can't find all of them. Especially, I didn't find the one for my dependends first came in the States. Thank you very much for teacher 8's quick reply to the question I posted yesterday!
-If you have been China and reentered US using a new visa such as H1, H4 after you graduated, you do not need to provide the copy of the I-20 for your I-485 filing. Otherwise, ask your school to find a copy for you.
