Hello . I have a question . Could you please help me . I was in USA last summer and I had a student 1 visa . My English as a second language program lasted 4 weeks . And there was a specific rule : " All students must leave a copy of back to their own country air ticket after finishing the program . So I left one . When I was already at home , they wrote me that I didn't leave a copy of air ticket , so they had to write something in my SEVIS and I probably will have problems with next trips to USA . But in fact I didn't do anything wrong . Am I really going to have problem with visa ? Could you help me please . Thank You ."...had a student F1 visa..."
