National Customer Service Center


Welcome to the home page of the National Customer Service Center (NCSC).

Through the NCSC, we provide nationwide assistance by telephone to customers calling from within the United States about immigration Services and Benefits. Service is available in English and Spanish.

The NCSC gives customers throughout the country another way to get consistent, accurate information and assistance on immigration Services and Benefits. We know that service by phone may be more convenient than having to write and wait for a reply, or having to take time off from work to go to the nearest Immigration office.
