Is an English marriage certificate acceptable for a Non-O visa application in Thailand?

Wow.

Having received answers from Meta/FB I hope your questioned is now closed.

If your wedding is registered normally in your home country and in Thailand, the visa application is completely easy. Your proof of income, the Khor Ror 3, a copy of your wife's ID card and you're done. I had my visa in Vienna within 6 days, although the Easter holidays were also there. You need the 0 on the Thai bank for the EOS, has nothing to do with the visa.

Plain and simple, if it flys, fvjks, floats or has a foundation rent it dont buy it. Follow my advice and you'll be a wealthy and happy camper.

Think hard about getting a visa based on marriage. There are many hoops to jump through and then just when you think you've done all requested, some more new requirements will be required by your local immigration office. It's much easier to do the normal 800,000 baht in the bank one or to use a visa agent

The New Zealand embassy sent me this link with all the information you need

Bring your passport, birth cert, and marriage cert to Bangkok.

You’ll need a special passport certification from your embassy

Then all 3 need to be translated and MFA certified

You’ll also need a Thai SIM in your name to open a bank account

I had to also get a yellow book and Pink ID to open a bank account

Also registering in Thailand as married (Kor Ror 22)

You’ll also need to do your tm30 and Thai address registration at your local immigration office

Get heaps of photos taken for ID / paperwork

I’ve attached info on the lady I used for the translation and MFA (ministry of foreign affairs) certification - not too far from the Australian embassy

Avoid Bangkok bank for your banking requirements as they seem to be problematic with freezing your funds (I’ve had KTB and Kasikorn accounts - prefer Kasikorn)

It’s has to be legalized first. Than translated

It has to be translated, then certified by the MFA as being an accurate translation.

The non-O visa IS the marriage visa. In Thailand you will never have a visa again, you will just have annual extensions. An extension is not the same thing as a visa.

You must get all of your marriage paperwork legalized BEFORE you travel to Thailand. This involves your government and the Thai embassy in your country (assuming that's where you were married). Then you have more work to do with the MFA and Amphur to get your marriage registered in Thailand. Once you get all of that done, you can get the paperwork you need to apply for the extension.
