What are the best options for obtaining a Thai visa after leaving Thailand for a month?

@Bonnie ******

Will not give them enough time upon return, OP said they want 90 more days. By that time (post ), they will only get normal 30-Day Visa Exempt, with 30-Day Extension possible thereafter. So they will either have to obtain another Tourist Visa, or leave country yet again and return for a 2nd Visa Exempt Entry.

@Graham *****

was right; they should have gotten an METV if this was their plan. C'et La Vie.

You already have a good plan. Visa free entry extend leave the country visa free entry extend leave the country

Your correct Visa for such a trip would have been the Multiple Entry Tourist Visa not the Single Entry. You may struggle to get a second 90 days without exiting a second time if you cannot get the second SETV.

Every country you listed does not use evisa. Evisa is not available in any of the SE Asian countries, you have to apply in person at a Thai embassy if you want a tourist visa.

Savanakhet Laos is known as one of the easier ones generally. But they still have strict requirements listed on their website. Many of the other embassies in SE Asia require an appointment and are sometimes booked out 1-2 months ahead, so you need to plan ahead if you are going to go that route.

There is no requirement to stay out of Thailand any amount of time, but with even 1 covid stamp in your passport you are probably going to get questioned every time you enter Thailand, even with a tourist visa. I suggest having the 3 proofs when you enter.

1) Proof of leaving Thailand within the initial entry (60 days if arriving with a tourist visa)

2) Proof of funds (20,000 baht per person or equivalent in another major currency IN CASH ONLY)

3) Proof of lodging (hotel reservation for at least the first few days if not more)
