Due to COVID-19 Pandemic, service disruptions at VACs and ASCs, for biometric collection have been extended. Biometric collection deadlines have been automatically extended from 30 days to 90 days, from the date mentioned on your biometric instructions letter.
Once VACs and ASCs re-open, you will be required to book a new appointment for biometric collection.
