The person submitting biometrics should bring the appointment notice and valid, unexpired photo identification (for example, Permanent Resident Card (Form I-551), passport, or driver's license), or other identity documentation as authorized by USCIS to the appointment.

Most of the time, the USCIS service center or the U.S. consulate handling your application will inform you of your biometrics appointment with an appointment notice (called an ASC notice), roughly 5-8 weeks after you file your application.

The biometrics appointment is all about ensuring that the person applying for a green card does not have a serious criminal record or any relevant prior immigration violations.

Ensure you bring a valid identification document such as a passport, travel document or national ID card. Ensure your fingertips are free from any forms of decoration such as mehndi/henna, cuts, abrasions or other markings as these may affect your ability to provide acceptable finger scans.
