In accordance with language specified in the Border
Security Act of 2003, U.S. Citizenship and Immigration Services (USCIS)
announced a change in the photo requirements for all applicants from
a three-quarter face position to a standard, full-frontal face position to take
effect August 2, 2004.
USCIS will accept both three-quarter and full-frontal color photographs until
September 1, 2004, after which only full-frontal color will be accepted.
The application process of customers who have already submitted materials
that include color photos with the three-quarter standard will not be affected
by this change.
