Due to Covid you need to come to Thailand first. You need to have a bachelors in any discipline to be legally hired. If your under 40, a native speaker, free of a criminally record and have a degree you’ll have no problem finding a job once you’ve landed in Thailand. Get a police clearance before you come.
If someone has an overstay they are ineligible for a Thailand Elite Visa. I can imagine the consequences are pretty severe for someone on this type of visa to overstay. I would suggest borrowing the money from someone and go get yourself an extension of stay asap. You should contact Thailand Elite immediately to find out what the consequences will be if you do overstay. I could see the elite visa being canceled but nobody knows until you contact Thailand Elite.
You tell them you must get an official receipt (blue paper) and all monies paid to them must be listed and accounted for on the receipt. 1,900 baht for any extension. No more. no less.
They might make your new extension one year from date of application rather than add to time left due to the fact you will be changing the reason for the extension?
It used to be some people stayed 20 years doing border runs with visa exempt but about ten years ago they started getting stricter and only want people on tourist visas to stay no longer than 6 months for any 12 month period. If they want to stay longer they need to get an applicable visa.
