What are the best long-term visa options for moving to Thailand at age 46?

Richard Heywood it is called the ED visa, you get with the documentation from the school you buy classes from, then, even though it is one year, you must extend it every 90 days with the documents the school gives you showing you are going to classes, and making acceptable progress, and, you can not legally work on it. If you actually want to learn the language, get the ED visa to do it, and then have a much better chance of getting a legal job, is to take the Thai language program at Chulalongkorn university in Bangkok. It is an intensive five month program designed to get you speaking, reading, and writing, Thai on a regular five day a week university schedule. This language program gets you up to speed faster than any language school, and in an academic setting. The better you speak, and read, Thai, the better chance you have at some very interesting jobs in Thailand. You want to stay in Thailand, and at your age this is the best way. You're not done working yet.

@Richard ********

if you are going to work remotely from Thailand there are only 2 visas that legally allow this, the LTR Work From Thailand Professional which it sounds like you won't be able to qualify for, or the much easier to acquire DTV based on Workation. If you plan to work inside Thailand I'd think again unless you have a particular skill that can't be served by Thais

@Richard ********

I know that you can't work on it, and that you have to sign up with a language school who will provide the paperwork you require to get the initial visa. You also have to extend the visa every 90 days which depends on your attendance at the school.

You would need to be employed outside Thailand
