As an Intergovernmental Organization (IGO), CERN is funded primarily through contributions from its twenty Member States, Associate Member States, and one Candidate for Accession to Membership. Accordingly, as is standard for IGOs, CERN recruits its Staff Members, most of its Fellows and the participants in its Student Programmes from nationals of these countries.

Staff members, Students and most Fellows recruited by CERN must be Member State nationals. A limited number of scientists from Non-Member State countries are accepted within the Associates and Fellows Programme.
Romania is a candidate to become a Member State of CERN and therefore Romanian nationals are eligible to apply for Student, Associate and Fellow programmes.
Serbia is an Associate Member State and therefore Serbian nationals are eligible to apply for Staff positions as well as Student, Associate and Fellow programmes.
You are considered by CERN to be a national if you have the passport of one of these countries. Marriage to a national or permanent residency does not, however, suffice.
