The U.S. Citizenship and Immigration Services (USCIS) released a news alert (10/3/14) advising that some of their customers have received more than one biometrics (fingerprints) appointment notice.
*Please note that we are not discussing a duplicate appointment notice as that happens as well, but an actual second fingerprint appointment notice requesting that the applicant appear for a second time at a different date and time.
They advise that if you have already shown up and completed a biometrics appointment and you receive a second appointment notice to please call the National Customer Service Center at 1-800-375-5283. They also stated if you have already received two appointments and have not attended the first, to bring the notices for both appointments with you and they will let you know if the second appointment is needed.
