I am a student from the US who has been accepted to study at the University of St. Andrews this September.
As I am in the midst of applying for my student visa, I noticed that there are two ways of "proving your identity":
1. give your biometric information at a visa application centre
2. use the UK immigration: ID check app to scan my identity document
I was wondering what the pros and cons were for each option, and whether or not you'll still need to hand in your passport for 3~4 weeks as part of the student visa process.
Thank you for the help.
