Around 1,500 Americans still in Afghanistan?

 National Review:

During a press briefing Wednesday, Secretary of State Antony Blinken announced that there are only roughly 500 Americans remaining in Afghanistan who wish to be evacuated.

He noted that out of 6,000 U.S. citizens who stated that they wanted to leave as of August 14, when the evacuation effort began, 4,500 U.S. passport holders were rescued, leaving 1,500 people, approximately 500 of whom are still actively looking for passage out. The numbers Blinken cited do not include those in possession of a U.S. green card, reporters confirmed at the press conference.

The State Department is trying to ascertain the status of about 1,000 U.S. citizens who have not contacted the U.S. government explicitly requesting evacuation. At a subsequent briefing Wednesday, White House press secretary Jen Psaki said the administration believes many of the 1,000 who are currently unaccounted for may be dual citizens of the United States and Afghanistan.

It is hard to imagine anyone wanting to stay under Taliban rule.  However, there are obviously some Afghans who are resisting the Taliban and a few provinces have already flipped back to the non-Taliban control groups.
