This is good,but Serbian-American. From the contest can also mean a Serbian that settled in the US, well going by the movies, The Men Who Built America, I will try and study the contest they were referring to by saying Serbian_American immigrants.

I am asking a physical student, and I understand how you feel.

I am just saying that serbian-american sounds like he was born from a serbian parent and american parent, which he was not for sure. He was a serb who lived in america but NOT born in america. I am just saying that the expression the writer used is not suiting.
