Someone studied in the US under a F1 visa and a scholarship. No other substantial income other than that. This person while in the U.S. had to file tax forms, although there was no tax to be paid because this person had no income outside the scholarships. The student finished the studies in, say, October last year and then left the country for his home country. The student graduated and does not intend to return to the U.S.

The educational institution sent the student's home address some tax form that he had to file by April 15, but the former student forgot to do that.

The question is: would the student have problems getting a U.S. visa as a tourist and entering the U.S. several years after that? If yes, how could that be fixed? Thanks in advance.
