No, it is not necessary to have a working permit for the duty station before applying for an international contract position with UNOPS. However, it is important to note that UNOPS requires candidates to have the legal right to work in the country where the position is located, either through citizenship or a valid work permit.
If you are selected for a UNOPS position, the organization will work with you to obtain the necessary visas and work permits required to work in the duty station. However, it is important to note that the process of obtaining a work permit can take time, so it is advisable to start the process as soon as possible after being selected for the position.
UNOPS also provides support and guidance to employees on immigration and visa-related matters. If you have any specific questions or concerns about working permits or immigration requirements for a particular duty station, it is recommended to consult the job posting or contact UNOPS HR for more information.
