What type of visa should a German citizen, born in Thailand and currently in South Korea, apply for to stay longer than 3 months in Thailand?

Marry an 80++ year old Thai.

If either of your parents were Thai you have been Thai from birth, it's just a matter of establishing that to the authorities.

If you can demonstrate this to the Thai consulate in South Korea you should be able to get a passport from them. Then you can stay in Thailand as long as you like.

There is also an option of a 1 year extension of stay you can get in your German passport if didn't have a Thai passport on entry but you can demonstrate to immigration you are Thai once here.

If neither of your parents were Thai, you _probably_ aren't entitled to citizenship, although it is possible depending on the exact circumstances.

This is in general terms, right now, returning to Thailand is difficult even if you are Thai, albeit possible. It's impossible right now for most non-Thais.

In normal times, if you are not Thai, the METV would be a good choice, but you have to get this in your country of residence. You still have to "bounce" every 90 days, but you can get almost nine months out of that.

Most visas that allow you stay longer than 90 days without bouncing, or get an extension longer than 90 days, require you having a reason to be here, like studying, working, marrying a nice Thai man, being over 50, etc. Elite is a hassle free option that doesn't need a reason but it's pricey (starting at 500,000B for 5 years).

If you are not Thai, I would suspect it will probably be at least the last quarter of the year before you will be able to come in. No-one knows for sure though. They might start letting non-"essential" foreigners in from August. But I suspect September-October at the earliest is more likely.

You are a foreigner in Thailand

Probably a question to ask the german and thai consulates. Having a thai passport would let you into the country now. Everything else is extremely difficult to get in on

If you were born in Thailand, you can get a Thai passport.

Learn Thai with an ED visa. A ministry of Education certified school can process the paperwork while you are in Korea. It is also common to process your ED visa while in Thailand. There is a. ED visa for self defense

In Chiang Mai and

Muay Thai ED visa too. There is teaching. Some schools teach Deutsche, but I think mostly in Bangkok. A degree will be needed. A few examples. This will all be a available at the proper time. Plan early. Research early. Tschuss
