Can I apply for a Non-O visa while on a 60-day visa in Thailand?

@Gregor *********

did you read his post? He said you can use the extension if you don't have enough time. You cannot convert to a non-O visa unless you have 14-21 days left on your stamp, depending on the immigration office. If you don't have enough days left then you get the extension then you apply to convert visas.

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

Both of these things are not true. There is no ETA coming, it's on indefinite hold. Also there is no 180 days rule, never has been.
