This I isn't from anywhere. Casey/miltownkid/miltownkidZEE are/were from Milwaukee, WI.
Born and raised until 21, then raised in Taiwan until 27, then raised some more in Milwaukee until 33, then freedom mode unlocked in the Philippines: http://miltownkid.com/2013/04/25/born-in-the-philippines/
Didn't fully wake up from the freedom mode until I was back in Taiwan though... Go figure. (Physical body mode is in Taiwan as he types this.)
