If you had paid the Biometrics fees with your Application Processing Fee during the submission of your application, you don't have to pay anything additional at the time of giving your biometrics. And as for the delay, it doesn't matter because in the Biometrics Instruction Letter (BIL), they specify that you have to finish it in 90 days. So I presume, the allowance for Biometrics has already been made. It usually doesn't take more than 20 days though.You are right ; in USA appointments are available only after 14 days. Do we need to pay any additional charges for Biometric Appointment ? Also Does this delays (of 2 weeks ) the overall progress of the application or these are simultaneous activities.
