You just go to immigration and get yourself an extension for 1900B.

Overstay for two days would be 1000B and a pretty bad stamp in your passport that could lead to problems in the future. That is if you're not caught during those two days and put in detention.

For a merely 900B difference just avoid problems and get yourself an extension.

I'm studying Thai, but in my school there are foreigners studying English and Chinese under an ED visa... As long as the school and program are guaranteed by the ministry and it isn't the native language of the foreigner, what is the problem with it?

It depends on what you're going to study.

If you enroll in university studies, as in official degrees, you can obtain a new visa every year until finished (4-6 years depending on the degree)

For things like Thai, Muay Thai, etc... depends on the subject, but max one or two years.

Regarding her situation, I'd say a visit to the Thai consulate in Berlin should get her a Thai passport if she is Thai citizen - but without ID surely it will be needed more paperwork.

Maybe she could just travel to Thailand under her German passport, and arrange everything (ID and passport) while in the country, what surely will be easier. Then travel back to Germany (to get the out stamp) and back to Thailand with her new Thai passport

I already know everything regarding that.

AFAIK I only can extend an ED three times based on reasons of studying - what I've done already. What's not correct in my opening statement?

I'll enroll in the advanced level if (when) I could stay here for a few months, being it under an ED or any other visa.

I'm just asking about if I acted smart or stupid by extending it on July - I mean, I'd like to know, if I wouldn't extend on July, would I be eligible for extension after amnesty? I'm asking just to make my mind up, just to blame or congrat myself.

I already have my (fare flexible to change dates) plane ticket back to EU for late October as I knew that that is the expiration date of my current permission of stay. I'm not asking "how to stay more and more" - I'm just asking if my movement in July was smart or not.

@Robert ******

and I can "extend" my course as it's a rolling course not based on semesters, and have more levels to study after the level I applied for last year.

I know. But as I could keep studying in the same school, I was just wondering if I could extend "after amnesty" in case I didn't before.

I know (I assume) that I can't extend anymore now. Just wondering if I acted smart or stupid back in July 😉

The residence certificate you must go to the Airport office. For the 90 days, in the Airport the drive-thru is still working, so you can do both in the Airport if you drive your car/bike for the 90 days report and then park and go for the residence certificate.

Your school have to prepare the paperwork for the work permit and send to you (FedEx, etc). Then, you apply for Work Visa based on that work permit. Workers with valid work visa and work permit are among the few foreigners allowed to come into Thailand.

No, it will not be valid. You will need a new visa.
