This case is not unfounded, and there are cases where you may be a refugee and, therefore, wouldn't have a valid identification document used to verify your identity. In that case, you may use the official immigration documents that recognise your status and contain your full name, date of birth (DoB), and photographs. If your immigration identification does not have a photograph, full name, DoB, or is pending approval, you can use this together with an authorisation letter. The authorisation request must be submitted no later than two days after booking. You must bring the authorisation letter and the identification used on test day.
