To reduce the long lines around USCIS offices, the agency is beginning a new program requiring visitors to make appointments before they arrive. The program, called "InfoPass," is already in effect in Los Angeles, Miami, and New York. It will soon be expanded to other cities.

If you need to visit USCIS -- whether to submit an application, pick up a form, or ask a question -- check the USCIS website first to see whether InfoPass is in effect at your local USCIS district office. If it is, you have little choice but to make an appointment (some offices will allow walk-ins if there's space, but don't count on this).

Appointments can be made only through the Internet. If you don't have a computer with Internet access, go to your local library, or a nonprofit organization that serves immigrants. Look for a computer with a printer -- you'll need a printout of your appointment notice when you visit. (Also, be sure to bring photo identification and any paperwork associated with your immigration case to your appointment.)

To make your appointment, go to www.uscis.gov and click the InfoPass link on the right side of the page. You'll be asked to enter information and can request when you want your appointment. You can use this same website to cancel your appointment, if necessary.
