Everyone must take general knowledge test plus all the other filters regardless of citizenship or whether doing direct entry or bridge program. If accepted and put through the Bridge, it cosists of 5 weeks of aviation subjects (aerodinamics, weather, W&B, performance ,etc) with tests for each, plus final test covering all. Must pass everything with 75 % and 9 sim sessions on TP IFR simulator with progress and final checks. If everything is succesfull (regardless of citizenship) then u can move on into the actual type rating courses. if not... well you know
good luck
