IMO FAL Convention
Shore leave without a visa
The Facilitation Convention’s Standard 3.44 requires public authorities to allow crew ashore while the ship is in port once arrival formalities are done, and Standard 3.45 states plainly that crew members shall not be required to hold a visa for the purpose of shore leave. Since 1 January 2018 shore leave must be granted without discrimination by nationality, race, colour, sex, religion, political opinion or social origin, and irrespective of the flag of the ship.
Where it stopsIt covers shore leave from a ship already in port. It is not a right to fly into a country to join one — that is the distinction that catches crew managers out.
