The only thing with it not being done is that they will not process her I-765 without biometrics. Over the last few months, looking at lots of timelines here, YT and other places, the I-765 usually gets approved within a couple of days after the biometrics and the card is received within 10-15 days after that. My wife just wants to work... not too concerned with the processing time of the AOS so much. Another reason the K-1 route is inferior I guess....
