On a non immigrant O-A visa application does the address in Thailand where you will stay have to be for the whole twelve months or can it be for an initial week or two in say a hotel while you look for long term accommodation?

I recently obtained a 90 day Non - Immigrant ED Visa . Since then, I've had to renew my American Passport. I have a few questions.

What do I do when it comes time to apply for my first 90 day extension? I have read on here that immigration will not transfer the sticker, only the stamps. Do I just bring both passports and the letter from the US embassy to facilitate the transfer of the visa between the old and new passports?

Do I need to do anything with the new passport at immigration once it arrives? My address has been registered since the day I entered under the old passport. Do I need to re-register it under the new passport number? I have no plans to travel outside of Thailand during my studies.

Thanks in advance.

A quick question.

Can someone tell me what proof of address my wife can give to Phetchaburi Immigration, when reporting 90 days.

.

I will show a TOT Bill, but my wife has nothing connected to our address.

I just returned from a month's stay overseas, and I'm preparing to go to Immigration today to get my TM30 stamped. I'm still living at the same address. Can anybody explain to me just what is the reason for me to go to Immigration? After all, they saw my passport and visa at the airport when I came back.
