In accordance with the Staff regulations and rules and Administrative Directives, the PTS will provide a Daily Subsistence Allowance (DSA) and financial support to cover travel costs:

  • The DSA will be sufficient to cover related expenses during the training programme;
  • The PTS travel agent will reserve, issue and send the flight tickets to the participants for the most direct and economic route;
  • Funded participants are not allowed to purchase their own tickets unless, under exceptional circumstances, be authorized to do so and only if this proves to be most cost efficient for the PTS;
  • The PTS will make the hotel reservation and participants will pay the hotel themselves using their DSA which they receive upon arrival in Uppsala; and
  • Health insurance will be provided for the duration of the training.


Participants should apply for visas, if needed, at the corresponding consular office upon receipt of an Acceptance Note Verbale from the PTS, in order to ensure timely processing. Nominations arriving late may risk that the time required to obtain visas for the host country can no longer be met. In this context, the Secretariat wishes to advise that the host country requests a 5-week deadline for the submission of Schengen visa requests to the respective Mission.

The training program is open only for Station Operators from invited countries.
