Me and my wife travelled to South East Asia in 2017 and on the way back to the UK we had to do a layover in Iran. We didn't leave the airport nor did we get our passports stamped.
My wife would like to visit the USA soon but is wondering whether she will fail the ESTA application as it asks if you have travelled to countries like Iran since 2011? She would like to travel within the next two weeks and is aware that if she has to go through the US embassy route she might not make it in time. Please let me know your thoughts.
