Longoni: seafarer FAQ
- Is shore leave allowed at Longoni?
- Shore leave at Longoni is governed by Mayotte immigration rules, the flag administration's policy, and the port authority's local rules. Seafarers normally need their seaman's book + a shore-leave permit issued by the agent. Confirm with your agent before going ashore — local policy changes frequently.
- What visa or shore-pass do I need for Longoni?
- Seafarers calling at Longoni on a vessel are generally exempt from regular tourist visas under Convention 108 / 185 (Seafarers' Identity Documents) if their flag administration has ratified the convention and they hold an SID. The standard document is the seaman's book + ship's crew list. Mayotte may also require a shore pass issued by the agent. Confirm before you board the vessel — visa rules vary by nationality and by recent immigration-policy changes.
