<Li> The admission of any such state to membership in the United Nations will be effected by a decision of the General Assembly upon the recommendation of the Security Council . </Li> <P> A recommendation for admission from the Security Council requires affirmative votes from at least nine of the council's fifteen members, with none of the five permanent members using their veto power . The Security Council's recommendation must then be approved in the General Assembly by a two - thirds majority vote . </P> <P> In principle, only sovereign states can become UN members, and currently all UN members are sovereign states . Although five members were not sovereign when they joined the UN, all subsequently became fully independent between 1946 and 1991 . Because a state can only be admitted to membership in the UN by the approval of the Security Council and the General Assembly, a number of states that are considered sovereign according to the Montevideo Convention are not members of the UN . This is because the UN does not consider them to possess sovereignty, mainly due to the lack of international recognition or due to opposition from one of the permanent members . </P> <P> In addition to the member states, the UN also invites non-member states to become observers at the UN General Assembly (currently two: the Holy See and Palestine), allowing them to participate and speak in General Assembly meetings, but not vote . Observers are generally intergovernmental organizations and international organizations and entities whose statehood or sovereignty is not precisely defined . </P>
