The P-3 classification applies to you if you are coming temporarily to perform, teach or coach as artists or entertainers, individually or as part of a group, under a program that is culturally unique.

To qualify for a P-3 Visa, you must be entering the United States either individually or as a group with the intent of developing, interpreting, representing, coaching, or teaching a distinctive or traditional ethnic, folk, cultural, musical, theatrical, or artistic performance or presentation. Additionally, your visit should involve participating in a cultural event or events that contribute to the understanding or advancement of your art form. The program may have either a commercial or noncommercial nature.

Duration: The length of a P-3 Visa is determined by the duration needed for the visa beneficiaries to participate in their events in the United States. Nevertheless, the initial period is capped at one year.
Family Members: Family members of P-3 Visa holders can accompany them on a P-4 Dependent nonimmigrant status.
