DVWinner- the officer didn't ask questions. We promissed to tell "the truth and only truth and...." and she compared our original documents (birth certuficates, marriage certificate, passports, SS cards, IDs ..) from time to time she asked us to confirm our dates or places of birth, basically she went through all papers to make sure that all data is correct. Then she took our passports and asked us to wait in the lobby. After half an hour she came back with our stamped passports and told us that we are permanent residents from that moment and that we would recieve our plastic shortly in mail. The stamp is valid for one year and can be renew in case if we don't get plastic cards in mail. That's all.
