100-200% of credit line held for foreigners? - August 8, 2008
A reader explains: I was surprised by this requirement for non-Thais who apply for a credit card at Bangkok Bank.
A bank officer explained (and this is a direct quote): "Many foreigners do not pay their credit card bills and we have trouble following them. So we have a new policy."
If your work permit is over three years old (working at least 3 years at the same place) they hold 100% of your credit line from your bank account. If it is less that three years, they hold 200% of your credit amount from your bank account. If a foreigner has a Ministry of Foreign affairs card (meaning they are employed by a foreign embassy), this requirement is waived.
I have no doubt that Thailand remains a catchall for deadbeat foreigners, but this requirement is annoying for someone who has had a bank account in good standing with Bangkok Bank for nearly 20 years...
We are not sure how new this policy is as others have reported similar things in the past. In any event, banks like KTC and Kasikorn give out credit cards to foreigners very easily.
