Some of the important FAQ related to Biometrics:
Biometrics
What should I take to my biometrics appointment at the Application Support Center (ASC)?
You must take the following documents with you to the ASC:
Your photo identification. Acceptable types of photo identification are:
passport or national photo identification issued by your country
a driver’s license
a military photo identification
a state-issued photo identification
AND
All Receipt Notices that were issued to you in relation to your current application for benefits. This includes receipt notices for the Forms I-485 and I-765. It is very important to bring both notices. Biometrics are captured under each separate receipt number for each separate Form, and if you do not present both notices, it can delay the issuance of your benefit document(s) (i.e. EAD or I-551 Lawful Permanent Resident Card.) These notices also provide instructions to ASC staff to capture the proper types of biometric information for each Form type.
Will customers still submit photographs with their applications even if their photographs are digitally captured at an Application Support Center (ASC)?
Yes. In order to make the process as transparent as possible, customers should continue to submit photographs if required by Form instructions until the instructions are changed. The receipt notice (Form I-797) will instruct the customer to schedule an appointment with an ASC to have his/her biometrics (photograph, fingerprints and signature) digitally captured. These digital images will be stored and used in the production of benefit documents.
Do I-485 applicants under age 14 and over age 79, who do not need to be fingerprinted, still need to make an appointment at an Application Support Center (ASC)?
Yes, any I-485 applicant under age 14 or over age 79 needs to have his or her photograph and signature captured at an ASC. These biometrics are needed to produce the I-551 Permanent Resident Card ("green card"). Applicants in these age groups receive specific I-485 receipt notices that are printed with the ASC code of 2, which, when presented at the ASC, provide for the capture of the photograph and signature only.
Will the I-765 applicant receive the new EAD at the conclusion of the biometrics appointment?
No, scheduling and appearing for a biometrics appointment only ensure that the EAD can be produced once the I-765 is approved (adjudicated). In fact, the EAD cannot be produced until the applicant's biometrics are in the system. However, regardless of when the applicant appears at the Application Support Center (ASC) for biometrics capture, the order in which I-765s are adjudicated remains "first-in, first-out." If the I-765 application is approved at the NBC and the biometrics information has been successfully submitted by the applicant, a request from the NBC will be sent to our card generation facility in Corbin, Kentucky to create and mail an EAD card to the applicant.
Some applicants report having difficulty scheduling appointments for biometrics capture at an Application Support Center (ASC). Why do some ASC centers state that no appointments are available for 45 days?
The Application Support Centers must set aside a certain number of appointment slots for not only National Benefits Center customers, but also for customers of the other four USCIS Service Centers. If an applicant calls the National Customer Service Center to schedule an appointment and finds that slots are unavailable, the situation is most likely that there are available appointments, but the specific appointment time that the customer wants is filled. The NCSC scheduler is monitored daily and changes are made immediately if too few appointment slots are available.
Are the biometrics appointments related to the adjudication of Advance Parole?
No. Please make sure that two passport style photos are included with your I-131, as these are needed to produce the I-512 travel document.
