NATO and the UN generally have their own classes of visas that do not grant diplomatic privileges. In the US for example, there are NATO visas for NATO representatives, and G visas for members of international organizations [0] (although they made an exception to that and let the EU and African Union representatives enter on diplomatic A visas) [1]. The funny part is that this is a total tempest in a teapot. Diplomatic immunity hardly ever gets used nowadays; the only real advantage to diplomatic status is avoiding the London congestion taxes.
