For Visa Stamping, need to go Visa Interview and Biomatrics

I have filed and get visa extension. One or 2 week later i will travel to india (I don’t have valid visa. But i have valid petition). Before come back USA, i need to stamp visa in my passport.

For Stamping Visa, Should i take visa interview and bio metrics tests?

If you are not eligible for dropbox facility, then you have to schedule visa and biometrics appointment.

Thank you Saurabh. Its useful to me.
