I’ve been using visas in expired passports for decades. You have to transfer Thai visas like Non-O/B/PE/SE to new passports, but it doesn’t affect validity. With DTV which is most times is stickerless, you won’t have to do anything, most likely

You can keep your old passport and use visas in it

Absolutely. Can be done even with visa-exempt stamp

Signed letter is not equivalent to TM30 in any shape or form. What you need is a screenshot from the online registration system.

Did you check in more than a week ago? That stupid online system only allows you to go back one week or so. They probably reported your stay as required, but can’t produce evidence

The easiest way to do it is to fire you and switch to contract-based employment. I know lots of people working for multinational companies headquartered in Germany and everyone based outside Germany (EU, US, Ukraine, Russia, Brazil, you name it) are on "freelancer"/"consultant" contracts (working full time, some people have been working like that for more than a decade)

usually works like this: you ask your school's admin staff, they prepare the papers and tell you the branch to go to. You're all set

ED is a long-term non-immigrant visa, it’s never been a problem to open a bank account with ED. DTV is a completely different story

@Greg *******

Well, it was similar to opening a bank account - first they ask for a WP, then dig through their internal instructions which don’t mention TE, and then you get “mai dai”

Most likely no. You need Non-O/ED/B. I was turned around even with Thailand Elite

Sure it will work, why not
