Hi,

I am under 50 years old and would like to study in Thailand to learn and extend my stay in the process. (according to the Thai Embassy http://www.thaiembassy.org/hochiminh/en/services/2911/35219-Non-Immigrant-Visa-%22ED%22.html, It is 90 days and ability to get 1 year extension)

Is there any known prominant and/or trusted schools to study language?

How do I determine if a school is trustworthy/reliable in providing necessary requirements for the ED visa?

Thanks very much.

You will only get 90 day extensions now and you will be limited to one year of total stay from the date you enter the country on an ED visa. After the year you will have to go out for a new visa and start a new year.

You should look here and perhaps post a topic to ask your question about schools for where you will be staying. Language school courses
