says most immigration offices don’t want to do the extension. Adding to that for your part 3 question, Phuket requires at least 15 days left on your current stamp to even consider doing it. Other offices may vary.

The rule is 2 months prior to application, leave at 800k or above for 3 months after application and can’t go below 400k for the rest of the year.

Two weeks is ample time for application. You could even do it on the 28th - but not recommended.

Go visit your immigration office and ask for their hand out of what documents are needed (can vary from office to office).

Most likely when you apply you’ll be given a “under consideration” stamp for 30 days -during which time they’ll probably arrange a house visit.

When you go back after the 30 days you’ll be given the remaining 11 months stamp.

Everything is done online. Some embassies do call people in for an interview but I’ve not seen any posts about Pretoria doing that.

A non O visa is valid for 90 days from issue. This means you have 90 days to wing your way to Thailand.

On entry you’ll get a 90 day stamp. Should be ample time to open an account and fund it for your extension.

A non O visa is valid for 90 days on entry. The OP will be away for 4-6 months. A re-entry permit isn’t going to help. They need a new visa.

The British Embassy in Bangkok hasn’t issued passports in decades.

Yes. You use the company called VFS Global to renew if you do it yourself. Contact them to arrange an appointment and details of what’s needed.

Alternatively use

to take any hassle out of doing it yourself. Great service.

You can only get an extension for one year or as long as your passport is valid until whichever is the shorter. The fact that you only had 9 months left when you extended means you only got an extension for 9 months. Completely normal.

You’ll have to get the stamps transferred and apply for a new year extension when that stamp is running out.

When you get your new passport you take it along with your old passport to the office that issued your extension of stay stamp (it’s not a Non B visa) and get the stamp transferred.

No idea why you think it’s a money making thing as the transfer is free.
