Can I extend my visa in Thailand again after the first extension, or do I need to do a visa run?

Good 🤞

If you're wanting to stay till September you should get a 60 day Tourist visa at a neighbouring embassy. That plus a border run and extensions will get you 150 more days here.

you can apply and will be denied and that will cost ya 1,900 baht and give ya 7 days to leave

save the 1,900 and head to a border

Visa run for another 30 days visa excemtion wich you can extend another 30 days at immigration

You can get one extension per entry.

A visa run is usually referred to as when you visit a nearby consulate and buy a new visa.

I suspect you’re referring to a “border bounce” where you exit Thailand and immediately return to get a new free exempt stamp (this time it will be 30 days).

You can do two land border bounces on exempt entries in a calendar year. Perhaps you’ll get away with one more via air but no guarantee.

Nope only get one extension per entry into Thailand
