I've just been through the registration process. I submitted my application in mid February, had confirmation I was through to interview stage in mid April, had my interview last week, and have been told that result could be another 5 - 6 weeks. So 22 weeks or more is entirely possible I'm afraid! But I would think you should hear something fairly soon - I assume you got an automated acknowledgement email with an application ref number? If you're concerned then best bet is to contact the registration team using details in the acknowledgement email. Good luck with your application!
