there is no 12 months stay that Visa is only available as a single entry 90 day Visa they discontinued the year-long multi-entry vases when they went to the online eVisa website
The whole process is online now, go to the e Visa website, login, start uploading the documents and entering the data as the program requests it.
Check that you got the data entry correct before you submit the application, because data entry error results in an automatic denial.
It's a straightforward process, no need to be worried about it, it's not a bad consulate to deal with.
If they need more documentation they will email you.
If you have other questions you could always post on the Aussies in Thailand FB group and ask as you'll get better answers there seeing as those people only use Sydney or Canberra for visas.
And just like that, seeing as this thread devolved into a how can I cheaply move money by wise and will it work at immigrations conversation, we are done.
They advised you to do that because you have to be married for two calendar months before you can apply for an in-country 90 day Non-O visa based on marriage to a thai.
So follow what they say and then when that last 60-day stamp is down to a couple weeks ago apply for the in country Visa like they said.
only IF you can prove that the transfers originated from abroad. That's not a topic for the group, sorry, that's between you/wise and your receiving bank
You are not changing from a retirement visa to a marriage visa.
You aren't on any retirement visa right now, and if you looked at your stamp I would bet it would say "extension of stay permitted until" and have a date that your extension is good for.
What you are actually doing is changing the reason for your extension from one based on retirement to one based on marriage and all you're doing is applying for a brand new extension which is why he gave you the TM7 application for extension paper.
You'll go to the immigration office, apply for a new extension for 1900 baht, you will get a 30-day under consideration stamp (because it's an extension based on marriage to a thai) and when that stamp runs out you go back and they will ink in the one year extension of stay.
now if you are using banked money method where you have the 800K banked you DO definitely need to follow the rules about when and how much you can access the account (y) because failing to do that will definitely run you amuck the following year when you go for the next extension
