Beginning Jan. 12, 2013, U.S. Citizenship and Immigration Services
(USCIS) National Customer Service Center (NCSC) will expand its live,
toll-free telephone assistance service to include Saturday hours.
Customer service representatives at NCSC will now take calls Monday
through Friday from 8 a.m. to 8 p.m., and Saturdays from 9 a.m. to 5
p.m., local time. Customers will be able to call the toll-free
number on Saturdays to receive nationwide assistance for immigration
services and benefits offered by USCIS.
On Saturdays, the customer service
representatives can answer routine questions on a wide variety of topics
related to immigration services and benefits, including ordering forms,
processing times, and information on local offices and civil surgeons.
For individuals seeking answers to more complex issues regarding their
case, USCIS recommend calling the NCSC Monday through Friday for access to
Immigration Services Officers. Individuals calling the NCSC can access
information through a menu of automated options 24 hours a day, 7 days a
week.
Contact the national toll-free customer service line by dialing 1-800-375-5283.
