NIS Rules for Marine Crew and Expatriate Permits in Nigeria

The Nigeria Immigration Service (NIS) controls entry, residence and work authorisation for every foreign national in the country. For marine and offshore projects, the distinction that causes the most confusion is between seafarers signing on or off a vessel and expatriate specialists coming to work on a project ashore or offshore.

Seafarers Signing On and Off

Crew arriving to join a vessel travel on a seafarer route supported by the crew list, letter of guarantee from the agent, and confirmed vessel details. Crew going ashore during a port call need shore passes coordinated with the NIS and the port. Signing-off crew need onward travel documentation ready before they leave the vessel, not after.

Temporary Work Permit (TWP) for Technical Specialists

The TWP is the standard route for expatriate specialists coming to perform short-term technical work — divers, ROV technicians, commissioning engineers, surveyors, auditors. The employer or sponsor applies to NIS headquarters, and once approved, a visa on arrival pre-approval is issued and presented at the port of entry.

  • TWPs are time-limited and tied to a specific scope of work
  • Extending the scope without re-applying is a breach
  • Approval timelines should be built into the mobilisation schedule, not treated as a formality

Business Visa on Arrival (BVoA)

BVoA supports genuine business travel — meetings, negotiations, inspections and conferences — and does not authorise hands-on technical work. Using a business visa for work that should carry a TWP is one of the most common compliance breaches on marine projects.

CERPAC, Expatriate Quota and STR Visas

Longer-term expatriate placements require the employer to hold an approved expatriate quota position, with the individual regularising residence through the Combined Expatriate Residence Permit and Aliens Card (CERPAC). Quota returns must be filed regularly with documented understudy arrangements. Subject to Regularisation (STR) visas are the route for expatriates taking up longer-term employment: issued abroad, then regularised into CERPAC after arrival within the prescribed window.

Staying Compliant on Every Project

  1. Match the permit class to the actual scope of work before travel
  2. Keep permit validity longer than the deployment period
  3. File expatriate quota returns on schedule
  4. Carry copies of approvals at all times — checks happen at airports, heliports and project sites
  5. Start STR to CERPAC regularisation immediately on arrival

PeaceRyde processes TWP and BVoA approvals, STR and CERPAC regularisation, expatriate quota support, seafarer documentation and shore passes, and provides airport meet-and-greet so crews clear immigration without friction.

Key Takeaways

  • Seafarers and expatriate technical specialists travel under different immigration routes
  • A TWP, not a business visa, is required for hands-on technical work
  • Expatriate quota and CERPAC apply to longer-term placements
  • Permit validity should always exceed the planned deployment period

Frequently Asked Questions

Can a technician work in Nigeria on a Business Visa on Arrival?

No. BVoA covers meetings, inspections and negotiations only. Hands-on installation, commissioning or repair work requires a Temporary Work Permit.

What documents does a seafarer need to sign on a vessel in Nigeria?

A confirmed crew list, a letter of guarantee from the vessel agent, and matching passport and seaman book details are the core requirements for the seafarer entry route.

What is the difference between STR and CERPAC?

STR is a visa issued abroad for expatriates taking up longer-term employment. After arrival, it must be regularised into a CERPAC within the prescribed window to establish lawful residence.

How long does TWP processing usually take?

Timelines vary with NIS headquarters workload, so sponsors should submit applications as early as the mobilisation date is confirmed rather than close to travel.
