I submitted my application at GCKey on 1 March and provided my biometric information at the UK Visa Centre in London on 15 March. However, as of now my application has not been reviewed. I then submitted a second application through Potal on 11 June and as of now, it has still not been reviewed. I am Chinese, however many of my classmates who submitted their visas in China at the same time as me have already received their visas. I would like to know if IRCC London is actually working?
