Question 3020 Deck General

The correct answer is B) Immigration Officer. The citizenship of a crew member of a vessel in a U.S. port is determined solely by the Immigration Officer, not the Coast Guard, Union Official, or Customs Officer. Immigration laws and regulations give the Immigration Officer the authority to determine the citizenship and immigration status of individuals entering the United States, including crew members of vessels. The Coast Guard, Union Officials, and Customs Officers may have other responsibilities related to the vessel and its operations, but the determination of a crew member's citizenship falls under the purview of the Immigration Officer.
