As you may know, USCIS requires photographs and fingerprints for certain applications, this process is called Biometrics. Until the Biometrics step is complete, an applicant can not proceed with the rest of the application, get his work permit or be scheduled for his Naturalization interview if it a Citizenship Application.
In many cases, applicants can not make it to the assigned fingerprints/biometrics date assigned by USCIS. Failure to show up can be detrimental to the case in hand, and can result in case termination.
A recent update from the San Diego AILA chapter may be useful to readers of this Blog and is applicable in all 50 states.
