Customs and Border Protection Border Patrol Agent (CBP BPA) Practice Exam

The D-2 classification requires individuals who are crew members of a vessel or aircraft to present a Form I-408 (Authorization to Pay Off or Discharge Crewman). This form is specifically designed to allow non-immigrant crew members to be discharged from their duties on a vessel or aircraft and effectively authorize their payment for any outstanding wages upon discharge. The necessity of this form is tied to the regulations that govern crew members' statuses, as they must formally apply for the discharge process, ensuring compliance with U.S. immigration laws.

In contrast, D-1, D-3, and D-4 classifications pertain to different categories of crew members or specific situations that do not require the completion of Form I-408. For example, D-1 typically refers to principal crew members who are not being discharged; D-3 may apply to crew members in transit or on temporary duty that might not necessitate a formal discharge; and D-4 is related to those who are not expected to remain in the U.S. or require a different arrangement. Understanding the specific use of Form I-408 within the D-2 classification highlights the unique administrative and legal considerations necessary for crew members exiting their roles on vessels or aircraft.
