NOT building a base, rather a facility on one of our bases. Years ago I met some here from Singapore.

FYI - GOOGLE AI Overview

Many foreign nations, including Germany, Spain, Italy, the Netherlands, and Belgium, have pilots who train in the USA through programs like the Euro-NATO Joint Jet Pilot Training Program.

Germany
Greece
Italy
The Netherlands
Norway
Portugal

Civilian training programs
Thousands of foreign nationals pursue civilian pilot training each year at Federal Aviation Administration (FAA)-approved flight schools across the U.S.. Countries with pilots who often train in the U.S. include:

European nations: Many pilots from European countries, such as the United Kingdom and Germany, come to the U.S. for training due to the comparatively lower cost.
India: Indian students are known to pursue pilot training in the U.S..
Latin American nations: A wide array of students from South and Central American countries attend U.S. flight schools.
Tunisia: Pilots from Tunisia have been reported to train at U.S. flight schools.
Venezuela: The U.S. has also trained pilots from Venezuela.
