Step 3: Biometrics Appointment
About a month after USCIS receives your green card application package, you will receive a notice in the mail with the time, date, and location for the biometrics appointment. Typically, these appointments are scheduled at the local USCIS field office closest to where the couple lives.
The purpose of this appointment is for USCIS to take fingerprints and photographs of the spouse seeking a green card, in order to conduct background and security checks. USCIS collaborates with other government agencies like the Federal Bureau of Investigation (FBI) to complete these checks.
The biometrics appointment is typically low-stress and can be thought of as more of a procedural step. The spouse seeking a green card will not be asked questions about the marriage or about green card eligibility at this appointment. He or she will simply be fingerprinted and photographed. The U.S. green card holder spouse is not required to attend this appointment, and often does not attend.
