Similar experience having a Dutch and Russian passport, when I travel between the two countries I show my NL passport in NL and RU passport in RU, get the comment ‘oh but you don’t have a Dutch/Russian visa’ and then show them the other passport. I never travel anywhere else with the Russian one though, because from what I understand if I get in trouble I will only get consular assistance from the country whose passport I used to enter.
So in your case, if you use your Thai passport to enter Laos, you’d have to ask the Thai embassy for help if anything happens.
Omg I didn’t know this… so what things do you need the RC for? (I’m waiting for my visa to come through and wanting to open a bank account, get a car and motorbike license, buy a car, transfer my motorbike to my name… what else would I need a RC for?)
Can I ask for all these RC’s at once at immigration?
What do you mean ‘they prefer work category instead of soft power’? The soft power makes you eligible, regardless of preferences of consulate/embassy staff, no? (If you have the correct paperwork of course)
You say you saw many being rejected, any idea why?
(this link is for Bangkok, there’s other email address when flying into Phuket). They will also tell you what their requirements are in regards to vaccinations, passport, health certificate from the origin country (cannot be older than 10 days, most airlines will also require this), etc.
Check the requirements of the airline you’re flying with.
Check what is needed to bring your dog back to the US. Probably you’ll need to do a titer test, best to do this before you leave for Thailand.
It’s all a bit of paperwork, but I always find the people at the Thai veterinary authority very helpful (I’ve traveled back and forth with my cat a few times, to EU)
