treaty limits Norway's right to collect taxes to that of financing services on Svalbard. Therefore, Svalbard has a lower income tax than mainland Norway, and there is no value added tax. There is a separate budget for Svalbard to ensure compliance. Svalbard is a demilitarized zone, as the treaty prohibits the establishment of military installations. Norwegian military activity is limited to fishery surveillance by the Norwegian Coast Guard as the treaty requires Norway to protect the natural environment. Svalbard is not governed by Norway's policies on migration and does not issue visas or residence permits itself. Foreigners do not need a visa or work and residence permits from the Norwegian authorities to travel to Svalbard. However, foreign citizens with a visa requirement for the Schengen Area must have a Schengen visa when travelling to and from Svalbard via mainland Norway. The Svalbard Act established the institution of the Governor of Svalbard (, formerly ), who holds the responsibility as both county governor and chief of police, as well as holding other authority granted from the executive branch. Duties include environmental policy, family law, law enforcement, search and rescue, tourism management, information services, contact with foreign settlements, and judge in some areas of maritime inquiries and judicial examinations—albeit never in the same cases as acting as police. Since 2021, Lars Fause has been governor. The institution is subordinate to the Ministry of Justice and the Police, but reports to other ministries in matters within their portfolio. Since 2002, Longyearbyen Community Council has had many of the same responsibilities of a municipality, including utilities, education, cultural facilities, fire department, roads, and ports. No care or nursing services are available, nor are welfare payments available. Norwegian residents retain pension and medical rights through their mainland municipalities. The hospital is part of University Hospital of North Norway, while the airport is operated by state-owned Avinor. Ny-Ålesund and Barentsburg remain company towns with all infrastructure owned by Kings Bay and Arktikugol. Other public offices with presence on Svalbard are the Norwegian Directorate of Mining, the Norwegian Polar Institute, the Norwegian Tax Administration, and the Church of Norway. Svalbard is subordinate to Nord-Troms District Court and Hålogaland Court of Appeal, both in Tromsø. Although Norway is part of the European Economic Area (EEA) and the Schengen Agreement, Svalbard is not part of the Schengen Area or the EEA. Non-EU and non-Nordic Svalbard residents do not need
