you will get you application number once you get your AOR. If you want to link it to gc key, You need to use the UCI number of your parents.Hi all, I submitted all the documents but haven't received any update for PGP 2021. Is this normal? Also, can anyone guide how to link application to GC Key? It asks application number or UCI or family name etc. I don't know what is application number and also UCI is of the sponsor or parents? and lastly, can the application be linked to anyone's GC account?
