Philadelphia has always been a welcoming city to immigrants from countries all over the world. In Philadelphia and the surrounding area, there are approximately 15,250 Ukrainian immigrants, as well as over 54,300 people of Ukrainian ancestry. In addition to providing a haven for Ukrainians, Philadelphia has welcomed thousands of immigrants who have had to flee their homeland for a variety of reasons. For example, when the American troops withdrew from Afghanistan, ending the 20-year war, Philadelphia International Airport welcomed over 30,000 evacuees.
