Expert Answer: No, a B1/B2 visa is strictly for tourism, business, or medical visits and does not authorize employment in the U.S., including working on a vessel.
1. **Work Authorization**: To work legally, you would need a specific work visa, such as an H-2B (temporary non-agricultural worker) or C1/D (crew member visa) if the job is related to maritime work.
2. **Applying for a Work Permit (EAD)**: A work permit (EAD) is generally not available for B1/B2 visa holders unless they change status (e.g., apply for asylum or another eligible visa category).
3. **Possible Options**: If an employer is willing to sponsor you, they may petition for a work visa that allows employment on a vessel, such as an H-2B or C1/D.
Working without proper authorization can have serious immigration consequences, including visa cancellation or future entry bans. If you’re interested in legally working on a vessel, consult with an immigration attorney to explore your best options.
