<p>The US military stationed at RAF Croughton are covered by the Ministry of Defence and governed by the NATO Status of Forces Agreement and Visiting Forces Act. Under an arrangement reached in 1995 there is also an Annex of the US Embassy in London based at RAF Croughton. The US Embassy, including the Croughton Annex, is under the same obligations as any other diplomatic mission.</p><p> </p><p>Under the Vienna Convention on Diplomatic Relations they must notify us of the appointment of members of the mission, their arrival and their final departure or the termination of their functions; and the arrival and final departure of members of their families. They must also notify us if someone becomes, or ceases to be, a member of such a family. These obligations apply as much to US Embassy staff at the Annex at RAF Croughton as they do in London.</p><p> </p>
