Parker has appeared for Germany at the under-15, under-16, under-17, under-18, under-19, under-20, and under-21 levels but still remains eligible for the United States due to having an American father. In 2012, it was revealed that United States manager
Jürgen Klinsmann had spoken to Parker about representing the United States in the future. Speaking on his international preference, Parker said, "It is a hard decision to make of course. One should be very proud to play for the country your father is from. I am playing for Germany now and this is my home base. Both sides are very interesting. I like Germany now, but I won’t rule out that I will play for the United States in the future." ==Personal life==
