Forget this stupid lawyer idea. It WON'T work! Embassies have the right to reject with or without a reason. Just go to Vietnam and apply under soft power category. Far much easier and cheaper. Lots of people are getting approved that way.
I've yet to hear anything positive about the DTV from so-called "agents". They always say something negative, and usually untrue, about the DTV. Plenty of Pakistani passport holders have already obtained the DTV.
There's a Pakistani who got approved by the Thai Consulate in Guangzhou. He obviously must have a Chinese residence permit to apply there. My point is there's hope if you have residency in another country.
Well, that was quite stupid of you, and your post just seems to bring unnecessary drama here. Most sensible people know you present BOTH your passport and visa printout to the officer. You don't just hand over your passport and expert them to guess what visa you're arriving on. Delete this ridiculous post! You're making a fool of yourself.
Your friend is right, nothing will happen, as long as you don't go to the immigration office. Ignore these repliers saying you'll "be fined". Nobody is looking for foreigners who didn't do their 90 day report. It's only an issue if you take yourself to an immigration office, which being on a DTV, I have ZERO clue why anybody on a DTV would do that.
Don't make too much drama out of this. Yes, you were scammed. But you have the DTV. Just find something else to justify your stays for the next 5 years in case immigration asks. If you escalate this to the authorities it will probably backfire on you. Just walk away and keep your DTV.
Each consulate or embassy may have it's own website but it's just for information and contact details. You can't submit an application on those websites. The official site for all Thai visa applications, including the DTV is
