Participants and the media are responsible for obtaining visas, if required, for entry into the Netherlands. Visa requirements and exemptions for each country are listed here.

Delegates whose country of residence does not have a consular mission of the Netherlands may obtain a visa from the mission of another country that is also party to the Schengen Agreement and that could be issuing visas on behalf of the Netherlands.

If you need a letter to accompany your visa application that confirms your attendance at CSP-22, contact one of OPCW’s Visa Assistants.
