Is it easier to apply for a 3-month Non-O visa in the UK or Thailand?

Since the Question is about "easier" the process includes banking. From personal experience getting a Bank Account with just a Tourist visa is almost impossible (not quite but almost). Once I got my Non-O based on Retirement it was STILL a difficult process until I stumbled into Krungsri. Several other banks had to many hoops to jump through. So put that into your equation.

I agree with

@London ****

getting a 90 day single entry Non-O visa in the UK using the eVisa system is NOT difficult and you can show funds in your UK account to get it

Then when you come in you'll get stamped in for 90 days and have time to get a bank account opened get the 800K baht in it and let it season the required 2 months so you can apply for a year extension at the immigration office for 1900baht before the 90 days runs out. You'll get a 30 day under consideration stamp and go back when that runs out to get the year inked into your passport.

This is the link for the eVisa system (if you're applying before you go back make sure you say you hold a UK passport and your permanent residence is in the UK or the system won't let you apply online)

UK is very easy. As long as you have funds showing on bank statement - UK funds are fine. As already said, all online - they send msg if need anything else. I got mine 2 days later. £60>

How about before we get into the proz/conz of where it's easier to do it the O/P (that'd be you

@Jason *******

😉 ) weighs in and says whether they're in thailand now or not 🙂

It's more straight forward applying in the UK from the comfort of your settee . It's all Evisa now .

It al depends on where you are.

If you're in the UK, apply in the UK

If you want it to do in Thailand you need to transfer money into a Thai Bank before you can apply, opening a Thai bank could take some time but also need time left on your current stay.
