Can I get an extension for my non O visa in Thailand if I have a medical condition and I'm about to start teaching?

1 year extension based on marriage

Requires 40k per month proof of income OR 400k in bank for 2 months.

If you have one of the above you can get the 1 year extension

Keep it simple, as you are married you can use that to get the Extension of Stay, you can use your income made as teaching English to meet the financial requirements

>I've had a visit family extension already and now on amnesty so do you think Samut Prakan immigration will give me another one?

Probably not. The immigration offices give out only one extension of stay based on visiting Thai family either per visa, or per entry stamp.

>Or also I do have a medical condition with my foot

You may be able to get a 30 day extension of stay based on medical reasons, however that's if you're under doctor care, and you can not physically fly out. Talk to your doctor.

>Any ideas

What's your nationality? You may be able to get a "hard stamp" in your passport,which may be able to be converted to an extension of stay based on employment (which is what you want, right?).
