Thanks. I applied inside Thailand, no insurance required. I was merely asking literally what it’s called - O or O-A - because it was a question on a form I had to fill out.
You renew the passport when you don't have any travel plans & have time to get the new one back before doing any traveling. I had my 90-day check in coming up, so waited until after that to renew the passport, when I wouldn't need it for a month or 2. (Didn't take that long, just in case.)
I'm not an expert, but in my experience, only one of the people can register as owner. i.e. I registered as owner of the unit I co-own, & was then unable to register my husband as also an owner. So I need to report myself as resident, and also my husband when he returns from overseas. The paperwork - in addition to our papers from the purchase, we needed the number from the blue book.
Solved - I'm an idiot! I didn't notice, at the top of the form you can check "foreigner" - and then it asks for your passport & nationality. I've registered.
I'm American, and I entered Thailand from Hong Kong with my emergency U.S. passport with no problems. I did not go to my home country. Should be fine, my emergency passport was fully accepted at immigration, airlines, hotels, etc. Carried the previous one along with it, but nobody ever had a problem with the emergency passport.
