I applied yesterday morning for pre-approval, uploaded all the relevant documents including my new Non O visa received from London. I got an automated email informing me that my registration had been received. included was a 6 digit code to check the result of my registration.
Today I tried several times to log on using the 6 digit code, but keep getting a pop up message "Sorry your information could not be found in the system". Luckily I haven't paid for a plane ticket yet.
