My citizenship interview is scheduled in July. I got my yellow letter just asking to bring state ID or DL. Four years back, I had crossed border to visit Tijuana, Mexico and while getting back, an officer troubled me with lot of questions and I answered to the point. He called his supervisor and I heard him telling that 'this guy is not clean'. Supervisor looked at me carefully and advised him to record this. I was clean and had nothing on me other than I had bit drunk. I was not driving any car. He photocopied my passport, GC and DL before he let me go. Other than this I never had any arrest or issues. Will there be any impact of this incident on my naturalization?
