TM 30 question. I did use the search function
I am Rvisiting the US next week for two weeks. I have been living at the same address in Bangkok for 1 1/2 years. I have a Non-Immigrant O-A with a multiple entry stamp good until Nov 20, 2018. Do I have to file a TM 30 with Bangkok Immigration when I return? I will be going to Immigration sometime within the 45 days before my Nov 20 date to extend my stay another year. I recently completed a 90-day checkin. Thanks.
