Strictly speaking - yes Bangkok bank needs you to swear a declaration in standard form on your residential address when opening a bank account. Apparently every embassy has the template n is used only for Bangkok bank. Found out when I opened my bank acct last year
To be honest - your expectations of jobs n work will have to be moderated.
There are very limited jobs for foreigners n even if there is, you will find the pay is far short of what you earn back home and u have to adapt to live like Thais.
Cities have grown very expensive- prices are now like Singapore n nice things are getting expensive. So standard of living have to be managed.
Regulatory red tape is horrendous and basic living visa are also difficult to get or understand.
As a foreigner u will always be respected n expected to pay more than locals.
That is my 2 cents worth.. lol
So as what many commented - go live in the province but then again depend on what you want at this stage of your life.
