I want to note that my husband and I, US citizens, applied at the same time earlier this week for our METV’s using the same credit card. His payment would not be accepted. He tried multiple times using different computers, different credit cards, and making 3 different applications. etc. We contacted the Thai Embassy and the Visa Officer advised to change browsers, clear the cache, among other things and to wait 15 minutes before trying again and to use a bank debit card. It finally went through, but what we found out is that the Thai Bank - Kasikorn- rejected the card payment and contacted the bank in the US. The US, bank in turn, contacted my husband and asked if he wanted to authorize this payment. As soon as he said yes and resubmitted payment, the application was processed. The Thai Embassy said this has been happening a lot since the Visa Application was revised. The Visa Officer was great and tried to be so helpful during this stressful and frustration time.
