Seafarer Immigration and Visas

Visa problems ground more seafarers than medical issues. A missing transit visa discovered at the airport, a documentation error on a seafarer identity document, or an ETIAS registration forgotten until the day of travel can delay a ship's departure, cost the operator money, and seriously damage your professional reputation. This guide covers the key visas and immigration documents every working seafarer should know about.

Your Seafarer Identity Document (SID)

Most maritime nations issue a Seafarer Identity Document alongside the passport. In the UK this is the Continuous Discharge Certificate (CDC). For other nationals it may be a Seaman's Book, Seafarer's Book, or similar. The SID is not a travel document in itself but is required alongside your passport for port and vessel access. Always carry both.

C1/D — US Transit/Crewmember Visa

The C1/D visa is required for non-US citizens joining or leaving vessels in US ports. It covers both crew transit and vessel sign-on/off. It is one of the most commonly needed and most frequently overlooked visas in international seafaring.

• Who needs it: Any non-US citizen working on a vessel calling at US ports, or transiting the US to join a vessel elsewhere
• Who is exempt: Citizens of Visa Waiver Program countries (including UK nationals) for transit only — but NOT for crew sign-on/off, which requires the C1/D regardless of nationality
• Processing time: 2–8 weeks typically; allow longer in busy periods
• Validity: Usually 5 or 10 years, multiple entry
• Cost: $185 application fee
• Apply at: usembassy.gov — select the US Embassy/Consulate for your home country

If your vessel trades to US ports and you don't have this visa, get it now — not when the rotation comes up.

ETIAS — EU Travel Information and Authorisation System

ETIAS applies to non-EU/EEA nationals who are currently visa-exempt for the Schengen Area — including UK citizens post-Brexit. It is an advance travel authorisation (not a visa) required before travel to Schengen countries. Expected to launch in 2025/2026.

• Online application, valid for 3 years or until passport expiry
• Cost: €7
• Must be linked to your specific passport
• Required for transit through Schengen airports as well as entry
