On December 11, 2014, USCIS announced that all 10,000 U visa petitions available for fiscal year 2015 had been approved.
Congress has allocated only 10,000 U visas a year to victims of certain crimes who have suffered substantial harm and have obtained certification from law enforcement confirming that the applicant has cooperated with the investigation or prosecution of a crime. This is the sixth year that USCIS has approved the maximum of 10,000 U visas.
USCIS issues conditional approvals for U visa petition if a case is approvable but can’t be approved because there are no numbers available. After a case is conditionally approved, USCIS will also accept and approve applications for interim work authorization.
