Is Biometrics required again - H4 to F1

[Kumar49809]

Hi

I have a couple of questions: 

1) If a person got h4 stamping in 2016 in Hyderabad, India (Gave Biometrics on first day and interview on the next day) Now if that person is going to India for F1 stamping for this fall. Should bio metrics be taken once again? Or is it valid for 10 years once taken in Hyderabad, India.

2) How to confirm if biometrics is valid or not?

If they want biometric once again they will give an option to schedule one. I am sure they want everytime. Do not think about these things and just go on and schedule an appointment...
