It was on their computer screen highlighted in bold that my wife would need a re-entry visa upon her return in February. It wasn't a unilateral decision made by the counter lady
I have and did at the airport prior to eating the ticket cost and aborting flight. Again, she has been back and forth several times, never an issue but she couldn't risk not being able to return to America
This is what we thought and how it's always been for her but they flagged her airline ticket and put in bold dark print that she would need a re-entry permit upon return
