To make an appointment with the United States Citizenship and Immigration Services, visitors must access the InfoPass system and complete an appointment request, according to the American Immigration Center. InfoPass is an appointment scheduling system used by the USCIS to schedule appointments online.
After entering the InfoPass system, the user must select a language, enter a ZIP code or country of residence, and detail the reason for the appointment, explains the American Immigration Center. The user must also enter personal information, such as name, date of birth and phone number, and select a date and time for the appointment. A confirmation then appears with details of the appointment, along with further instructions about what documentation to bring to the meeting.
