Sorry that means even haviny the valid biometric for the visitor visa is not enough and they will ask for another one?I am in the same situation, my mom received the Biometrics on 29th Jul and we completed Biometrics on 03rd Aug. Biometrics was OK and it is valid for 10yrs. My mom is with us as Visitor for more than 18months.
Thx
