In a very interesting case out of the state of Illinois, a young man is currently being held in an immigration detention center as a fugitive despite his insistence that he has sought to secure citizenship through the proper legal channels.

Eugene P., 28, was originally born in Nigeria, where he was part of the Ogoni tribe, who are well known for their protests against petroleum drilling in their region of the country in the 1990s.

It is rumored that in response to these protests, oil companies enlisted the assistance of the Nigerian military. This in turn, created an extremely chaotic and dangerous environment that Eugene P. sought to flee.

He is currently appealing the detention as his deadline for the appeal of his green card had not expired when he was taken into custody.  Eugene also married a woman while living in the United States – three days prior to being arrested and detained by an ICE worker.
