What are the rules for extending a tourist visa and visa exemption in Thailand?

Stephan Wolf Fowler correct, that's all they can extend a 30 day visa exempt entry. BUT they are not limited to just two 30 day visa exempt entries by land in a year like most people either. They can border bounce all the want by land

Janya Ning, he could go to the Thai consulate in Vientiane Lao and get a tourist visa easily. I'd say, because it's an emergency and he doesn't have time to get a tourist visa before he comes here, just have him come in on a 30 day visa exempt entry, extend that for 30 days, then go get a tourist visa at a thai consulate in a nearby country

@Tony ********

, witch, really?! Sorry, just can't stop laughing =)))

He will have to fill out a T.M.6 On the plane he can write your address on there.

And will be

handed in on arrival into Thailand

@Ja***

, he is unlikely to get questioned at all coming in to thailand if he doesn't have an extensive history of living here on back-2-back visa exempt or tourist visa entries.

With that being said, once he's here, rather than flying out and back in to get a 30 day visa exempt entry stamp he would be better served spending the time in another country to get a single entry tourist visa. it only takes a couple days

But yes, a letter from you stating he'll stay at your place should work IF he's asked.

Most people that are questioned are asked about proof of funds (20K baht in cash or the equivalent in another currency) rather than proof of lodging.

@Ja***

, there is in theory no limit to the number of visa exempt entries someone can get when flying in BUT at some point they will be questioned by the officer at passport control and possibly be asked for proof of funds, proof of a hotel booking and proof of onward travel <-all of those are legal requirements that you hafta show when asked.

He should go to a thai consulate and BUY a tourist visa so when he comes in he'll get stamped in for 60 days (and he can extend that for 30 more days too).

Very good Tony, keep it up the good work

Not everyone knows.

@Janya *****

a UK passport holder would get 30 day visa exempt entry and they could extend for 30 more days for 1900baht at the immigration office if they needed to

Ayahuasca, ALL extensions of stays (no matter what you're extending) get added to your current expiration date so you never lose any days by going early.

Also single entry tourist visas are valid for 90 days from the date they're issued <- meaning you have 90 days to enter thailand and get stamped in for 60 days.

@Ja***

, no :/

a visa exempt entry gives you 30 days and you can extend that by 30 giving you 60

a tourist visa gets you 60 days and you can extend that by 30 giving you 90.

George Bowen yes
