What are the current visa extension options for TR visa holders in Hua Hin, and do both applicants need to be present in person?

Unless I'm wrong, Bluport isn't where you go for extensions in Hua Hin.

Last reports said they weren't doing ANY extensions, just 90 day reports and TM30's.

GO to the main office and ask them.

You have to go in person to get an extension. So you and your wife both need to go to the immigration office to apply for an extension :/

There are also reports that some offices are making new arrivals on 60 day tourist visa stamps get the 30 day 'regular' extension BUT some are just automatically giving them the 60 day covid extension. It's what ever the immigration office in your area decides to do .. Post on a Hua Hin f/b group and ask if any new arrivals on tourist visas got the covid stamp extension
