What is the process for obtaining a 60-day tourist visa at the Thai Consulate in Vientiane from Udon Thani?

I’ll let someone else step in

Depending on how you live , ie hotel or rental contract , you’ll need your TM30 updated if you rent a house here .

You can extend when you have under 30 days remaining I believe. They will stamp you in for 30 days after the "leave by" date, regardless. Bring 1900 baht, TM.7 form, and I believe passport copies.

When people refer to agencies there are different meanings. In Vientiane it is not possible, as in Penang/Malay, to hire someone to do it for you, you must do in person. We as agency from Bangkok or other agencies can bring the people to Embassy and can help people (our customer) to apply for visa, we can help in asking the employer to send addl documents , etc., but no agency can "ask" for special bla bla bla. Vientiane is very straight forward.

no need to ask private message. Even we are agency to run this service, it is easy to do alone. When you reach Udon Airport, please take early flight, take a minivan , I think, THB150or200 to border, about 45minutes. Stamp out of Thai, bus bus ticket to Laos side, THB40.-, buses leave every 5 minutes, on the Laos side hand in the form for Laos visa on arrival, time depends on how many people there, not forget to stamp into Laos, than find transport to the Thai Consulate( which is at at different location as the Thai Embassy). At the Consulate just walk in and get the form, some girls will help and they ask to make some copy, you will get a number for next day pick up. That day around 13:30 they start to return passport and you pay when you pick up.

25 kilometres

Depending on how much time you have, consider a side trip to the charming riverside town of Nong Khai. If you are arriving in Udon Thani in the afternoon that would be perfect, take a mini bus from the airport to Nong Khai 200 baht, stay at least one night and spend the next day exploring Nong Khai before you cross over the friendship bridge into Laos

You need to go to the Thai Consulate in Vientianne, not the Thai Embassy. They are not close to each other

@Gavin *********

you can just paper clip them to the form

I was just there Monday. You need two passport photos (2.5x3.5 inches I believe, a smaller size) with white background, a copy of the photo page of your passport, a copy of your Laos visa, and a copy of your Laos entry stamp. The consulate has application forms. You can do that at the consulate for 5 baht/copy. You don't need anything else.

A flight out of Thailand and 20,000 baht cash would be good to have when entering Thailand, but Nong Khai land border is easy, I (and others) never have needed to show any of that. Arriving to Thailand by air may be stricter depending on the IO.

As others say, turn in form before 11:30am, pick up between 1:30-4pm the next day. The order for pickup depends on the order of drop-off.

Most as you can and official photo. Ticket to go back is always a good weight to get a visa.
