Can a Korean tourist extend their visa in Thailand before it expires?

Just pop down to KUL or SIN on a cheap flight. Come back and get another 90-days. 4 times per year and no worry for the first year.

Royal Jordanian has a convenient evening flight (RJ that leaves here at dinner time (5pm) and back before midnight (arrive BKK at 23:55). Don't even need to enter Malaysia.

Just get off the plane, go to the transit desk to get the boarding pass for the return flight and go back to the gate for the return flight.

I personally have never met a single Korean here on a real single entry tourist visa. :O (and I've met hundreds of koreans at the various thai language schools). They all come in on 90 day visa exempt entries. Some have been here years by flying out and back in every 90 days

Tell your Korean friend read 태사랑 on Naver. will get more information

@Jimmy ****

Hang about.

Did your friend BUY a single entry tourist visa from a thai consulate BEFORE they came here OR did they just show up and get a 90 day visa exempt stamp for free?

Koreans CANNOT get 30 day extensions on their 90 day visa exempt stamp they can ONLY get the 'extension denied' 7 day stamp to get out of thailand.

I thought, people who enter visa exempt through a bilateral agreement can not get the extension of stay?

Koreans are allowed what is called a 90 day exemption, it's not a visa. Before the days are up, you can get a 30 day extension as Robert mentioned. Most of the other countries are only given a 30 day exemption. I should know, I am from the US and my wife is Korean, we got the different treatment.

You can not renew a visa, only apply for a NEW visa or an Extension of Stay. Can you please describe what kind of visa he has, there is no visitor visa as I know of.
