I've meant to ask this for a while now but haven't got round to it until now. My husband(who entered the country on thre K-1 Visa from the UK a little over three months ago) has got a biometrics appiontment in Atlanta tomorrow. He knows what to take(passport and notice of the appoinment) but isn't too sure of what exactly it'll all involve. Any info would be appreciated.

Oops, I think this should be in AOS.

Regardless, at the biometrics your husband will have his fingerprints and a picture taken. It takes about 15 minutes to do it all. Of course, he may or may not have to wait depending on how busy the centre is.

Good luck
