You don't qualify for an extension based on marriage. Better to sort it legally as these dodgy agents will be closed down eventually. Borrow the money from your Wife.

Who are you volunteering with?

I would think that you would get a 12 month extension or a covid extension.

Working in Thailand with a work permit.

You can apply for permanent residency but it requires 3 years of paying income tax plus more.

Google IPTV. There are lots of them. Some are better than others. Subscribe (400 to 1000 Baht a month) and add it to your Android Box. Many even give a free trial. You will then get every channel you could ever want worldwide. For those technically challenged try Pulse TV who will supply the box with their system already loaded. Or download their app yourself.

Correct.

You can enter with a Tourist Visa of a Visa Except entry. Once here you can apply a for a Non Imm O Visa and after 2 months apply for a 12 month extension of stay. 800,000 Baht in a Thai bank needed for both of you. Or proof of 65,000 Income. Yes your wife can apply as your Wife with nothing in the bank needed but she would need to apply for the Non Imm O Visa outside of Thailand. Forget O-A Visa as it needs the rip off insurance to get one.

Who?

As said, apply for a Non Imm O Visa at Immigration then apply for a 12 month extension.

Tried Chicken Tikka Masala from Ruby Murry today. It was actually very good. Will be ordering more. Has a lot of choices. He will deliver on his motorcycle to Makro or Big C car park.

Your new extension will start on the day your current one ends. Always a good idea to do it early.
