What document? They only thing you might find is a policy for that specific branch set by the manager. Nothing has changed from the government.

@สก็อต ********

That person lied to you. The government hasn't changed anything. The government hasn't even been functioning for the last month. That bank branch just changed their policy and don't want to deal with foreigner paperwork anymore. The one down the street has different rules.

Try checking your statement in Thai language and see what it says there. Sometimes that is more clear.

@Stephen ********

As I said, you need to ask your immigration office before you start planning on using monthly transfers, because some don't let you use that for marriage extensions.

You cannot go to the nearest immigration office. You go to the immigration office that serves the province where you are registered as staying. That is not always the nearest office, as the nearest office may be in a different province.

If the 800k has not been in your Bangkok Bank account for 2 months at the time you apply for your extension, you cannot use that for an extension. You will also be required to keep it at 800k for 3 months after your extension and it can never drop below 400k until next year.

But none of that matters. Just go to Kasikorn Bank and get a credit advice showing that the money sent from Wise was an international transfer, and submit that with your bank statement showing monthly transfers.

Sounds like you did one of the non-official websites that offers the TDAC for free but also tries to upsell you. This is the official government site

You have to do things they way they are done, not the way you want them done.

When you apply for a non-O visa and you're on a tourist stay, you lose any extra days because it's not an extension, it's a conversion.

You cannot apply for the extension until you have 30 days or less left, or 45 days or less left at some offices. Since you start with 90 days, you cannot immediately apply.

You will have to submit whatever paperwork they ask for. You should get the list from immigration. If you already have a lease, you don't need a new lease. You use the one you have.

The embassy instructions are to print out the visa and hand it over with your passport. Without the printed visa, the immigration officer may make a mistake and stamp you in with a 60 day visa exempt stamp, since that's mostly what they do all day.

And ALWAYS check your passport after leaving passport control to ensure you received the correct stamp. It's very easy to fix then and there, and very difficult if not impossible to fix later.

Most immigration offices allow when you have 30 days or less left.

Some immigration offices allow when you have 45 days or less left.

A couple allow when you have 7 days or less left.

Since you have not indicated what immigration offices, your question is not possible to answer.
