Perfectly possible, many people have do it... But if you are not planning on living here I would not. You need a resident certificate though. Which you can get at your local immigration (requirements vary greatly by office) or through your counties embassy (usually just done as affidavit).
Someplace have agents to thay go with for the license to translate and help you through the process. Not sure where you talking though.
I am on elite.. So neither. Can you screen shot the requirements? This question comes up latelt.. It would be good to know the exact what they are requesting.
I have true wallet, it accepts foreigners.. But if I recall you are required to use passport plus any issued Thai ID.. In my case a Thai drivers license.
Duke is considered one of the best schools. I attended ALA. The school will help you get the visa, processes vary through. If you go to a good school and have never used an ED or any problems with immigration in the past, I am sure you will be approved for the visa with no worries.
the non-immigration elements of living here, any non-imm visa is better than elite. Elite is still classified as tourists visa in the small print of the law, and that can be a bit annoying. Elite simplifies the immigration process though a lot. A non-o need yearly extension and requirements... So if it's easy for you and guaranteed you can keep it for as long as you need, the non-o is probably better.
Elite won't allow you to work or get permanent residency/citizenship. If you require working, or wanting to get PR then it would not be needed.
Now you can have elite and still get a different visa to use. So if you have elite, but then take a job you can get a work visa and switch to it, you can switch back to elite later.
If you want to stay longer, I definitely encourage going to a Thai language school, which can get you a Ed visa for about a year. You get to learn Thai and a great deal of culture understanding.. This can only help your relationship with her and her family, give you a visa, and learn a new language. A true win, win, win.
Rosetta stones doesn't have Thai. There are a few apps that can teach Thai that are alright, I think Ling is the most recommended.. But it seems in my personal experience these apps all fall short. Going to a class, even online is probably much better, and there not too expensive.
