that’s right. I came on tourist visa. Changed to 90 day Non O retirement at Chaengwattana. Went back before 90 days for one year extension. I opened at Krungsri Sukhumvit soi 31. I dressed well, showed printouts of USA bank accounts with good balances, condo lease and copy of landlords ID, attestation of address notarized at US embassy (not possible now–you could see if immigration will do it, may take 2 visits, or try going to bank without it). They opened account with Visa debit card, mobile and internet access. I got proof from bank transfer was from abroad, I’m told that wasn’t necessary. I did not use an agent. Many agents use upcountry immigration offices, but it’s better that it’s your home office. I got the extension at the 90 day mark but they required a hand drawn map to my home, and agents showed up to visit, having my landlord and his father identify me and get their picture taken with me and their IDs. At my room they took pix of me with my passport and bankbook.
sometimes you have to block then yes. I have a simple answer on expats forum, small issue not so critical as one’s visa. Some guy I didn’t know posted a string of curses at me, crazy dude.
they also tax the shipping, not on what you pay fedex etc but on an imputed price depending on the size of the package. It’s probably doable. I’ve bought many items from amazon USA btw , never had a problem
