The U.S. has admitted 2000 – 2020 about 1.7 million persons as refugees/ asylees (refugees apply outside the U.S., asylees within the U.S.) (See here and here.)
The US post 9/11 wars have forcibly displaced at least 38 million people in and from Afghanistan, Iraq, Pakistan, Yemen, Somalia, the Philippines, Libya, and Somalia. This exceeds those displaced by every war since 1900 except World War II. This is a conservative estimate., The number may be closer to 49-60 million.
From these 8 countries, 7.9 million have sought residence in other countries.
2 million Afghans have been displaced outside their country since 9/11. Between 9/11 and 2019, the U.S. admitted about 90,000 Afghans, or less than 5% of those internationally displaced. It may admit 100,000 – 150,000 since complete withdrawal.
2.3 million Iraqis were displaced outside their country since 9/11. (Here and here.) Since then, perhaps 100,000 or less have immigrated. (The mayor of Dearborn MI is an Iraqi-American,). At 100,000 this is less than 5% of those international displaced.
