I was trying to submit secondary application and pay the fee. However, the website says" Ucna225 Tran Amt must be specified as a valid number". I don't know what happened... has anyone else has encountered this problem before? please help !! Thanks!!
If my memory serves me right... They only take certain credit cards from what I remember. Master and Visa credit cards are preferred. If you're 100% sure you've done everything correctly and it still doesn't work, call them.
