What type of visa do I need to visit and later teach in Thailand?

3 month tourist visa.

Then when you get a job they will help you with a work visa. English contracts can be short and your visa is dependant on it. So you it going to get 2 years without a contract that long. You’ll have to keep it up as you go. Usually contracts are 3 months. They repeat them. But keeping you only 3 months at a time is beneficial for labour laws. Most don’t apply.

The air quality is very different in different parts and seasons. Make sure there are hiring schools in the area you chose to try. As one place might be ok. And another not.

Northern has a burning season. I would stay away from any areas near them as the air quality is bad during those months. Some areas.. very bad.

I am in Hua Hin. I don’t notice much of anything. And the little rain showers help.

Thailand is a huge diverse country.

I assume you don’t have a degree, in which case English teaching is long hours and low pay.

Best to get a single entry tourist visa. You get 60 days and can extend it by 30.

Do you have a job offer yet? They will need to organise a work permit.

Have been here before? Allergies will be the least of your problems

If you want to become a teacher you will have to apply for a non-ed Visa but Thailand requires usually a bachelor's degree and teaching certificate they may not recognize your credentials and your country of origin another route is the non B twhich is a business Visa, your best bet is to go and explore the country first based on your post seems like you want to go for 90 days to see if her allergies can withstanding living in this country

You get a 60-day Tourist Visa and, towards the end of the 60-day period, get a 30-day extension.

Of course, you don't need that long to find out about your allergies, but,,,,,,,,

Good day non-o 90 day Visa you can apply for it while you're in the US and it opens up the door to educational visas extension of stays, Muy Thai depending on your income and your situation you could apply for the long-term visas they have a 10-year LTR. Thailand just reduced its tourist extension of stay to 30 days which I believe you could possibly extend it another 30 days you can actually leave the country and go to Malaysia or Cambodia and come back and I believe get another 30 days but according to what I read you can only do two of those per calendar year correct me if I'm wrong I'm just trying to help people here
