Application decisions
Application decisions are made by the General Committee and are expected to be communicated by late September or early October by email from the Technical Secretariat.

Applicants are advised not to arrange travel without receiving a written confirmation from the OPCW.
What is the General Committee?
A General Committee is appointed at each session of the Conference of the States Parties (including Review Conferences) and is made up of delegates from Member States representing each geographical region. The General Committee is responsible for considering the agenda of the Conference and for matters related to its organisation (see Rules 41-43 of the Rules of Procedure of the Conference of the States Parties, C-I/3/Rev.2, dated 8 April 2013).
The General Committee is responsible for reviewing applications for NGO attendance and participation. The Technical Secretariat compiles the details of NGOs applying for to participate and attend the Conference and submits the list for “vetting by States Parties through the General Committee”. Following the decision of the States Parties, the General Committee will notify the Technical Secretariat of which NGOs have been recommended to participate in the Conference (see Guidelines for Future Attendance and Participation by Non-Governmental Organisations.)
