Speak to Brian Ramsden of Lawyer for Expats (Thailand), he will offer you a free consultation, and particularly about the LTR-visa. He and his business partner Pook can also advise in other key legal areas.
a branch of a bank in Pattaya opened accounts for foreigners without following the bank's policies, and the individuals who obtained accounts were involved in criminal activity.
Banks are inconsistent with the application of their account opening policies which have certainly tightened up since the fraud uncovered in Pattaya several weeks ago. Even two branches of the same Bank apply their policy differently - it's down to an individual often. As a minimum now: Passport copy, Visa copy (with endorsement letter if LTR), Proof of Residence (Rental Agreement, Certificate of Residence, TM30 or House Book depending on the status and individual in the bank), ID from Country of origin (ie Driving Licence depending on the individual bank officer). Although copies of documents are accepted, they may ask to see the originals when accepting copies - same goes for obtaining a drivers licence.
We recently received our LTR-Visa via the E-visa system (within 3-days of applying) offered through the Thai-Embassies, after applying from outside Thailand through the BOI. We did not have to make the journey to Bangkok.
