My son is traveling with a classmate to the USA for 8 days. They are both 17 years old.
My son has an ESTA and is still valid. Now I read on the internet that normally we have to give a I-94 form when we depart from the USA, but previous time I did not received one or gave it to the officer at the airport.
Now my question is if my son can get trouble with this and if he needs special documents ? I emailed the embassy but they did not respond !
