But it says he spent his early life being raised by various foster parents. I don't see it being possible that he was raised by foster parents in some sort of foreign country.

The only time there is mention of him going to any Middle Eastern country (and it looks like a Middle Eastern typical rug behind Eli in the shot) is when he is inducted into the Green Berets  and takes part in a mission to Iraq in 1991.
