, you need to pay buy debit or credit card. There is a separate payment instruction form to fill out with your card details and submit with your application. You can use a Thai or UK card, doesn't matter. Just make sure if you use your Thai card, it is able to be used for international payments. When your application reaches the UK, the office in Liverpool will take the money in pounds sterling. Let me know if you need any other information.
