My hu*****and and I are preparing the materials for I-485 application. It seems that all the I-20 forms should be included. But I could not find the I-20 form I used when I used to enter US as F2. Just now, I called a friend, he told me that there is a stamp on his wife's I-20 form, which she used to enter US.
When the international students service office of the university issued the I-20 to my hu*****and to invite me come here, the office made a copy. The copy kept in the school is same to the one I used, but without the stamp.I could not find the one with stamp, so I got a copy from the school.
Now, my concern is whether I can just use the one without stamp for the I-485 application. Will it be a big problem?
Please give me a hand! Thanks a lot!
