Im originally German as you said. My father is German as is my mum and I was born there. My dad works for ExxonMobil hence we move around a lot. Im 16 in 2 months and moving to the U.S. was my 9th move.
I have lived in Germany (moved 5 or so times within) then Australia, then Qatar, and now Texas.
Im still a German citizen and university is good and free there. However I do probably have the option of studying where I want but as I see it its mainly Germany. Then again I have no clue yet what I want to do with my life.
Hope that helps ya out
(I go to the same school as DutchHerp but I am a grade above him)
