It's very clear in Thailand. You are married or you are not. As a mere common law spouse, you will not be recognized as a dependent. Get married and you can. Otherwise you both need to apply on your own.
to me, this is where AI will drastically change the world. All that info will be at their fingertips in an instant. We shall see how quickly different countries build out their AI infrastructure for immigration.
The visa being attached to tax filing is dead easy right now. You want a visa extension? Please show us your tax return.
To me, the leases are more complicated right now and would require dedicated officers to investigate. At least for now
it definitely adds a layer of complexity. If i was an incoming renter, i would likely be seeking out a Thai landlord. Which is probably the desired effect. Termination with cause might be the answer as the landlord is not in position to offer a legal 12 month lease. Which should allow the renter the ability to terminate. But i can imagine that lawyers are rubbing their hands with glee over this whole situation. So many billable hours. If what he is saying is true, you will need to either rent from a Thai owner, or seek out a foreign owner who can easily prove he has the necessary paperwork to offer a 12 month lease. It's gonna be a problem for some if it's true.
i just watched the video Gary is talking about. It's probably worth a look and judge for yourself what is being said. It's only one farang agent and he is in Pattaya where they might be targetted more than elsewhere. It would seem he has been told that foreign owners need to possess a long term visa (doesn't mean they need to be here though) and a TIN to have a renter with a 12 month lease (which they may need to qualify for visa). But let me know what you think about it after. Tough to tell at this point man
