pk. Firstly you can't carry 2 visas in Thailand. My guess is you were stamped in for 60 days on a Visa exempt....am I correct? I think your bank is blocking an overseas card as your applying in Thailand and not your home country. Am I correct?
yes a 60-day TR (TOURIST) Visa on the Evisa website prior to travel. When here get a 30-day extension. OR apply for a METV (multiple entry Tourist Visa) but this still won't guarantee entry to Thailand by the IO. you can apply for a NON O or NON OA on the website where you get 90-days
