Just today, as my wife flew from Japan to Thai, during her flight I sent 100K THB to her BKK Bank account, the money was waiting on her. A Thai national, her Internet banking that I have access to.
Quite likely, the account was opened with no visa number. Happened to many farangs who had their accounts open before this crackdown. Even 15 years ago.
"Just come" as it is like walking into a 7-11. And they , Immigration, give the documents over the counter and someone opens a bank account just as they please?
What you are saying may be possible with an agency.
From my residency nation (Japan), passport country is Australia.I Think it is a standard form, nothing special for me.
ID page of my passport they asked for , (no any other or blank pages), my picture, my ID of my residency (government issued). 3 months bank report (available online,m printed and attached it) that I have 800K THB in my local account. Approved in just over 5 days, Osaka, Japan.
