What does a D-1 visa allow a crewman to do?

The D-1 visa is specifically designed for crewmen working on foreign vessels and provides them with the ability to enter the United States for the purpose of joining and departing from a ship or other means of transportation. This visa allows them to arrive and depart as part of their duties with the same transportation line.

This is crucial because it ensures that crew members can fulfill their roles aboard their vessels while complying with U.S. immigration regulations. The conditions of the D-1 visa emphasize the connection to a specific transportation line, which is a fundamental aspect of the visa's purpose. Essentially, the D-1 visa facilitates their temporary presence in the U.S. strictly related to their crewman duties, ensuring they can join or leave the ship necessary for their employment while adhering to the legal stipulations of their visa status.
