That is a little more complicated than it sounds. That's because you would need to leave Thailand after the initial non-O entry was running out, and if you wanted another non-O you would need to apply from a nearby embassy or consulate.

I assume your passport qualifies for visa exempt, so a better plan is probably to apply for the non-O before you leave for Thailand. Then after 90 days do a border bounce and return visa exempt (no visa) and then you'll receive a 60 day stamp. Apply for the 30-day extension from immigration, which will give you a total of 180 days, same as 2 non-O visas but will not require the extra non-O visa application.

but at least for LTR they'll accept most any insurance policy that meets their requirements, unlike with the non-OA that only accepts policies from an approved list of Thai companies.

@Fabien ********

a non-O is not a tourist visa. It's a non-immigrant visa.

@Jyrki ********

not for the that embassy. But the UK embassy in Thailand doesn't certify income so there's no possibility of using any income for your first extension in Thailand.

@Yoni ***********

of course not. But you need paperwork from your job in order to apply for the non-B

Anonymous participant 937 Nong Khai was the easiest border in Thailand until recently. If you want a corrupt border look at Poi Pet before they closed the borders.

@Vesna *************************

that is not the EMBASSY website. You use evisa to apply through a specific embassy. You selected the embassy as the first question in the application.

What does the website of the embassy you applied through say? Every embassy has different processing times and even different visas have different processing times at embassies.

@Jay ****

You don't apply for anything through immigration. Visas are handled through embassies, not immigration. You must travel to a country where you want to apply. Then you apply through that embassy on the e-visa website which is the ONLY way to apply for a visa now. That application will ask you where you physically are, and will ask for proof that you are there and may be further confirmed by the embassy.

As I said, each embassy sets their own requirements. Some want 3 months of statements, some want 6 months of statements. Some only want the last statement to show required funds, some want every statement to show it.

METV gives you a 60 day stamp every entry. Each entry can be extended by 30 days. But you stated you wanted more than 90 days, so whether you came in with a visa or not, you would need to leave and return at some point because both visa exempt and tourist visa give 60+30.
