Hi! My son ,Italian nationality,holds a Non-O Immigrant visa attending school in Phuket. This summer we will return to Italy for the holidays where he will renew his passport as it is not valid for more than 6 months. My question is: can he return to Thailand with the new passport along with the old one ( where the Visa stamp is) without having problems at the airport Immigration, and then transfer the Visa in the new passport once in Phuket? Thanks for your help
