What I have heard (don't remember exactly where, but likely I read this in the Times or Post) is that there are an estimated 20,000 US citizens in Kabul. Many US embassies encourage US citizens abroad to register w/ the embassy whether they are visiting or traveling. I imagine that was especially encouraged in Afghanistan. I think I also read that the Germans want to evacuate something like 10,000 people, including some of their own citizens and some Afghan employees / dependents. Other Western powers likely have similar numbers.
