The US diplomatic mission in Iran has been extinct since the 1979 hostage crisis. This means that there is no American embassy on Iranian soil. Some visitors, however, can apply for an Iranian visa through the Pakistani embassy in Washington, D.C., but then they need to prove that they’re traveling with a tour group.
