Lo dicen bien claro, In general, unless otherwise exempt, any immigrant who is or has been a member of or affiliated with the Communist or any other totalitarian party (or subdivision or affiliate), domestic or foreign, is inadmissible to the United States. This ground of inadmissibility only applies to aliens seeking immigrant status, such as aliens inside the United States applying to adjust status to that of a lawful permanent resident.
O sea a todo afiliado o ex afiliado del partido comunista o cualquier otro partido totalitario ( o subdivision o afiliados) o sea partido que sea una subdivisión o afiliación del partido comunista
