What kinds of questions does US Customs and Border Protection ask of?
Some of the questions I got in the past:- How long were you overseas?- Which countries have you visited?- Are you bringing anything with you?- How much money are you carrying with you?- I see you were not born in the US. How did you acquire your citizenship? And how did you acquire your greencard? (Some of these questions are answered in the mandatory customs form, I was still asked about it).
