Crewpersons serving in good faith for normal operations aboard vessels docked temporarily in the U.S. may apply for D-1 Visas. This classification includes musicians, stewards, technicians, and chefs.
You may temporarily remain in the U.S. for as long as you are a member of the crew. People who are traveling with the D-1 visa holder may remain in the U.S. for as long as the D-1 nonimmigrant is allowed. Under certain circumstances, D-1 visa holders may be permitted to perform longshore work in U.S. ports of entry.
This visa does not apply to workers on U.S. fishing boats.
