United States
The Gulf of Mexico - deep, mature, and legally particular.
The USA is straightforward for citizens and permanent residents. For everyone else, the work-authorization route is narrower and must be checked against the specific vessel before you invest in an application.
Why the USA
A deep market with a narrow international entry point.
The Gulf of Mexico remains one of the world's deepest and most technologically advanced offshore basins, with dense operator activity and established logistics through Port Fourchon and the Houston-Louisiana corridor.
That depth does not make the visa route simple. Foreign nationals usually need a vessel-specific B-1/OCS basis tied to a foreign-flagged or foreign-owned vessel and a US Coast Guard Manning Exemption Letter. Most US-flagged routes are built around US persons.

Visa snapshot
B-1/OCS is not a general offshore work visa.
For international candidates, eligibility depends on the specific vessel, flag, ownership, and Manning Exemption Letter. MUSTER flags that constraint early and recommends confirmation with a licensed US immigration attorney.
