Extension (1st occasion of) of β€˜Non O’ based on marriage.

Ahead of me physically going there (I guess I could attempt to πŸ“ž call)

When is the soonest I can apply at the Sukhothai Immigration Office. I currently have 45 days remaining of non O. Too early?

Anyone go definitive?

Responses indicated that applications can generally be made no earlier than 30 days before the visa's expiration at this office.

The O/P is using the Sukothai immigration office and as he said they allow 30 days or less for extensions, so at least he knows for sure when he can go

We wish him the best of luck with his upcoming extension (y)

Visit immigration well before and ask the question, it is pretty easy even here.

Evidently the best course of action ahead of such question I posed here was to ACTUALLY go visit the immigration office in question. Now having just done that, I am officially informed that I CANNOT apply sooner than 30 days prior to expiry of my non O.(at this particular office at least, Sukhothai)

well at least you KNOW for sure that you can't apply until you have 30 days or less left on your current stamp πŸ™‚ Hopefully you got the hand out from them listing the documentation requirements as well

depending on your citizenship (you seem to have a British passport) on the day of application to the 1-year extension, you will need a minimum of 400,000 THB sitting in a Thai bank account in your sole name, for a minimum of 2 months. And on Immigration, you need to prove this with the letter statement of the bank and your updated on the same day bankbook

you do not need 400k in an account if you can prove 40k a month or have proof of 40k a month transferred from outside Thailand into a Thai bank the last 12 months.

the OP is British citizen, so his ONLY option is the 400,000 THB deposit in his Thai bank account. I repeat: his only option for all applications for the annual extensions of stay permit, unless he changes to the reason "retirement". Then he would need 800,000 THB minimum deposit

did you read
@Graham *****
's reply? The 12-months of transfers of 40,000 THB method cannot be had for any new extensions based on marriage. This would only leave as options the income proof by an embassy certified affidavit of income, or the 400,000 THB deposit

Can you explain why citizenship matters please

citizenship matters because embassies of some countries do not issue income affidavits. That's why citizens of these countries must do the financial proof with the deposit in their Thai bank accounts. Embassies that don't issue affidavits of income are for example those of the USA, UK, Australia, Canada and Norway

so you've been using the 40k transfer method for many years as most Immigration Offices no longer allow new applications to use this method

really? Does Immigration only allow the 12-months transfers of 65,000 for a retirement extension? Do 12-months of transfers of 40,000 for a marriage extension not fall under the same directive? Amazing Thailand 😢😢

only possible if you work in Thailand and pay taxes in Thailand, then you can use this proof of income. If you have income from outside of Thailand, you would need a legalized by your embassy income affidavit. Or you could use a 12-months bank statement of incoming from abroad month for month, not missing a single month, of a minimum of 40,000 THB into your Thai bank account

Yes, 12 months of bank statements showing payments from abroad, and the annual letter from my pension provider.

Raymond Parker . . your marriage must be registered inside Thailand, and on Immigration you need to prove your marriage to a Thai wife with a freshly on an Amphur printed marriage registry document, the Kor Ror 2 or 22 (whichever applies). A rose bordered marriage certificate (Kor Ror 3) is not sufficient.

Typically it's when you have 30 days or less left on your permission to stay stamp, but in some of the larger cities it's up to 45 days. You'll have to contact them and find out what their particular policy is. You should always contact your local immigration office well ahead of your extension date to find out what the current requirements are for your particular type of visa extension, marriage extensions usually have a lot of requirements.
