The correct classification for an alien traveling to join a vessel or aircraft located in the U.S. is the C-1 visa. This visa is specifically designated for foreign nationals who need to transit through the United States in order to board a ship or aircraft for immediate departure.

The C-1 visa enables the individual to enter the U.S. briefly for the purpose of joining a vessel or aircraft, which is reflected in its designation as a transit visa. It is essential for those coming to the U.S. for such specific purposes, ensuring they can legally enter the country to fulfill their obligations related to their maritime or aviation employment.

In contrast, other classifications such as C-2 are intended for more specialized situations, like aliens traveling to the U.S. to attend meetings or conferences for governmental purposes, while D-1 and D-2 classifications pertain to crew members of vessels or airlines. D-1 applies to crew members traveling in international waters or airspace, while D-2 is for crew members arriving to join a ship or aircraft but does not provide the same transit privileges as the C-1.
