Graham, he wants to apply for the "change of visa type" from a visa exempt entry to a 90-days Non Imm O visa. A "30-days tourist extension" is not the correct approach .. . google "change of visa type Thai immigration" and you will find the answer

"unlimited", until they tell you at the border that you can't

@Joe ******

yeah, by illegal legality 😎😂

@Joe ******

yeah, "grease the wheels" with an agent, bribe Immigration to look the other way. Of course there are a few illegal methods. Thank you for your insight

you shouldn't have gone to Penang in the first place, this consulate is known for being a chastice to applicants

@David *****

sorry to burst your bubble . . . . you ALMOST got it, yet it is not fully correct

Upon check-in with the airline in the U.S.A., you need to present your THAI passport, not your US passport

Because if you try to check-in with your US passport, you will either need a visa for Thailand, or the proof of onward travel within the 60-days visa-exempt you will get stamped into Thailand using a US passport. The airline is required to check

After check-in , you LEAVE the USA with your US passport

@David *****

??? Exit Thailand with Thai passport ??????? . . . . . . . . . This needs a slight correction, because you forgot something:

you cannot check in onto a flight from Thailand to the USA with your Thai passport - a Thai needs a visa for this purpose, or a stay permit for the USA stamped into the passport

So, the correct procedure is: Check-in to the flight with your U.S. passport, and exit Thailand through Immigration with your Thai passport

R. Lagas already smelled the rat. The rule is: as long as you have a still valid visa or a still valid stay permit, you need to cancel it before you are free to apply for another type of visa

@Incognia *********

because embassies and immigration are run by two different ministries, and actually don't communicate much with each other. The threadstarter is soon about to find out that he will get a problem, because he didn't cancel the ED-extension of stay, before he applied for another visa
