I got mine done today at the ASC in Elizabeth, NJ. You walk in and show the guard your biometrics appt letter and your identification. Then, he/she gives you a form to fill out & also makes sure you turn off your phone. You fill out the top and it's basic information, your alien registration # and your receipt numbers. You show the guard that you completed the form, then you walk to the receptionist line. This line is a bit longer but at that time, it took about 10-15 minutes to get to the desk. The receptionist at the desk writes in a few details on the form you filled out, looks at your ID, asks to look at your hands, then staples on a ticket with a number on it. NOTE: They were adamant about minors being accompanied by an adult, so plan that accordingly. Next, you wait in the biometrics wing at a seat until your number is called. When your number is called, you proceed to an area in the room. The technician asks for you to approve the info they have on record. Then, he asks you to sign an electronic notepad. Next, he sprays alcohol on your hands and takes 10 prints, and an extra one of your right index finger. After each finger, on the corner it'll say either pass or rejected. Once all of that is set, you sit down to have your picture taken for the EAD. After all of that, you're done and the technician might ask you to fill out a customer service questionnaire and drop it off. Then, you can go home and endure the hardest part: the wait
