Hi, I applied for EAD with premium processing on April 13 and am awaiting for a response for biometrics. I am confused about how does the 30 day clock work? does the clock start from april 13 and pause when you get your biometrics notification or does it reset to 30 days again, also is it 30 business days or calendar days.
My job start date is May 18 and looking at the timeline where i havent received my biometrics yet, I am extremely worried whether i will receive my card or not. Can y'all please share your timelines.
