Following clarifications with the Italian Administrations, the following is specified:

Seafarers from third countries for which a Schengen visa is required when crossing the external borders for embarkation, re-embarkation or disembarkation from a vessel on which they will work or have worked as seafarers (Reference standard REG (Ce) 810/2009) must submit the following documents to the Schengen Border Office:

• Disembarkation: travel plan with booking of tickets, letter of disembarkation or holidays, letter of guarantee signed by the Ship Agent of the port in which the seafarer will disembark.

For seafarers from third countries for which a Schengen visa is not required (reference legislation REG (EU) 2016/399) must submit the following documents to the Schengen Border Office:

• Embarkation / disembarkation / holiday rotation: seafarer’s identity documents issued pursuant to Conventions No. 108 (1958) or No. 185 (2003) of the International Labor Organization (ILO) on seafarers' identity documents (seamen’s book) printed FAL 5, of the Convention on Facilitation of International Maritime Traffic, showing the seafarer’s position on board, contract of employment, letter from the Ship Agent attesting the ETA of the ship in the port where the boarding will take place or a copy of the communications made to the authorities in the port where the disembarkation has happened.

With the presentation of the above documentation, the seafarer’s passport will not have to be stamped on entry/exit.
