I filed I-539 to get my parents stay extended in 2001. The application was approved.
When they left U.S. in 2001, they took I-539 approval letter with them.
I want to invite them here this summer but they can't find I-539 approval letter any more. And my fault I don't have a copy of that letter either.
Anybody has the same experience or has the knowledge of what I should do? Would that cause any issue on their B-2 visa? Would they get stopped at U.S. Custom even they got the visa?
Please HELP - I do want to get my parents here one more time before they are too old to handle a long trip like this (they are at their mid 70s).
Any advice will be helpful!!!
