AI Overview
There are no independent foreign military bases in the United States, but some foreign air forces have a presence on U.S. bases for training purposes, such as the Singaporean air force at Mountain Home Air Force Base and a planned Qatari facility at the same base. The German air force also has a training command at Sheppard Air Force Base, Texas.
Examples of foreign training presences

Qatar:
A new air force facility will be built at Mountain Home Air Force Base in Idaho to support the training of Qatari F-15QA pilots.

Singapore:
The Republic of Singapore Air Force has maintained a presence at Mountain Home Air Force Base since 2009, with its 428th Fighter Squadron training there.
Germany:
The German air force operates a tactical training command at Sheppard Air Force Base in Texas, and German pilots have been training in the U.S. since 1958.
Other NATO allies:
Pilots from other NATO nations, such as the Netherlands and Britain, frequently train in the United States.
Saudi Arabia:
The U.S. has a history of training Saudi pilots, though this was complicated by a 2019 incident where a Saudi officer killed three people at a U.S. base in Florida.
