I gave biometrics for my UK visitor visa application 3 weeks ago. I now want to apply for a Canadian visitor visa and the biometrics center is literally the same one I just travelled to and gave my previous biometrics. Is it possible to use the same biometric confirmation? I know this may be a long shot but it would really save me a lot of time and effort.
Nope, that would be a great way for someone to create fraudulent entries.
The center might be the same, but your data is going to two completely different systems so you'll have to visit again and provide the fingerprint data.
