My citizenship interview is in 3 weeks. The interview letter says "You MUST bring the following with you to the interview ... Any evidence of Selective Service Registration". According to the selective service web page (www.sss.gov), "No status information letters are required from the Selective Service System for: ... Non-U.S. male on a valid non-immigrant visa". I was on an F-1 student visa until past age 26. To establish this, I am thinking of taking copies of my I-20 forms and F-1 visas to the interview. Is that sufficient? Or should I try to obtain a status information letter from the selective service?
