Is it still the case that if I enter on a 30 day "Permission to Enter"...then get a 30 day extension locally (Ko Phangan Immigration)...will I be able to exit Thailand to a neighboring country such as Malaysia...and get another 30 day Permission to Enter.

I have done this once before...but pre-Covid.

I don't know if any of these are considered "Visas".

I will be arriving next week and just considering options.

Yes I know I could have applied for a 60 day Visa here in USA and probably extended that for 30 days.

Thank you
