I just became a permanent resident on October 12,2007. I have a question since I still have my I-94 in my passport, should it be a problem if i want to go overseas and just give the officer my green card? I still have my I-94 with me because I did not have any interview and just got approval on my GC. What do i do with my I-94, should i just leave it in my passport or take it out?
