What is the process for extending a Thai visa from Chiang Mai, and what are the cheapest border crossing options?

@Michaela **********

Go to the thai immigration office to get the extension and they will tell you what you need as far as documentation.

They EXTEND your stay, ADDED to your current stay. Not 30 days from day of application.

You can do it in Chang Mai any you want, it is added to your current stay, so you don't have to wait till the last day.

Yes, you can.

yep I saw that, and there is no official limit to them for russians BUT some borders won't let them bounce at all

I think she's Russian and the rules may be different for them (bilateral treaty), I don't think they have the 2 per year by land limit. Can they do Mae Sai?

@Tod ********

, may be you can answer this..

I was planning to go to mae sai soon, but i already have two 1 month stamp: one on arrival by air in november 2017 and one recently by land from malaysia..

Is that ok for me to go for one more one month stamp by land or already not? Thank you

@Robert *******

It has to be a pristine 10 dollar bill but you can make them take it if you push ;)

I've always paid with $10. A few years ago they usually needed persuading on this but I did it twice in 2017 and they took it with no questions.

Myanmar has always refused my $10. No doubt because it is rather cheaper. I don't bother trying US$ any more.

@Mich****

if you are really short on cash, the official Myanmar border fee is $10. $10 is less than 500THB. You can change the money here in Chiang Mai, or in Mae Sai just by the border (there is a gold shop that does it on the left). Saves you 170B or so.

@Mich****

, the fee at the Myanmar border is 500 baht. The bus has two seat options, regular at the back (cheaper) and the first 4 rows are larger VIP seats at a slightly higher price.

You can book you bus tickets online at the link Tod provided above and then go pay at 7-11 within a couple of hours... cost for return ticket is around 600 baht. You can take the 8 am bus to Mae Sai and 2:30 pm bus back. That gives you about 2 hours to take the song theaw to the border (15 baht each way), stamp in and out, grab a quick lunch and back to the bus station.

There will be others doing the same run so just follow them. Let me know if you have any questions.
