green card interview in 3 weeks, we planned a domestic trip the day after the interview. i came to the us as a child, and have no "valid" id, except for my passport (which has a picture of a 6 years old girl). i recently got it stamped valid, but they did not change the picture to a more recent one. i heard about a i-551 stamp? how do i request one from the interviewing officer? and also what will be my chances of getting through tsa with or without that stamp?
