Under typical regulations, you are exempted from import tax on personal effects only if you hold a one-year non-immigrant visa along with a valid work permit.
DTV visa holder is not permitted to work and not allowed to stay in Thailand longer than 180 days per each entry. It implies that you're not considered a tax resident of Thailand, hence you might not be able to enjoy the tax exemption.
If you apply for the re-entry permit, you'll be forced to re-enter with the same visa. I think you could hold 2 visas and activate the second one later. The issue is...would the 2nd visa be valid for that long.
I'm sure you're just joking, and I appreciate the humor! It's totally normal for things like this to cross our minds. Just a friendly reminder, though: if there need to be any changes to a visa stamp, there must be endorsedment by the responsible officer. 😊
yes, contact immigration office on ground floor, next to the elevator (departure). We used to experience this in 2019. If anyone experience this later, this info might be invalid.
