and? If I've run every red light my entire life and never been pulled over for it, does that mean it's legal? No, it just means I've been lucky. It's a legal requirement regardless of if you've ever experienced it or not.
No, no one can tell you. Each entry is at the discretion of the immigration officer you are standing in front of. Recent reports are people that spend 60 days, get a 30 day extension, leave and return within a few months are getting pulled out of line and interrogated. If you're a tourist, you don't need more time than that. If you're not a tourist, get a proper visa. It's only a matter of time until you are put into a bad position by being denied entry if you try to play games with Thai immigration in this current environment.
okay. You didn't mention that fact. Then there's still no embassy in Bangkok that can do anything, but even going to immigration in Bangkok wouldn't make sense since you can only apply in the province you live in. If you didn't live in Bangkok with a TM30 from Bangkok, they would turn you away.
You have to get your DTV visa issued first. Your spouse can then apply for a dependant DTV based on your visa. You must have yours first as one of the requirements for their visa is to upload a copy of your visa that has already been issued. Once they have the visa it's the exact same as any other DTV visa.
I have no idea what he was referring to. And you can only get the 1-year extension from the same province you got the initial visa from. So no, he didn't mean go to Bangkok for that because they wouldn't issue it if that's not where you got the visa.
Talking about an embassy at all in this regard makes no sense. There's no Thai embassy in Thailand. And a foreign embassy can't do anything about your Thai permission to stay.
20,000 baht or equivalent in another major currency IN CASH ONLY. Required of every tourist entering Thailand. Rarely asked for unless they want to deny you entry or have some suspicion of you.
