As the United States marks its 250th anniversary, The Global Story podcast is exploring the surprising and often hidden ways the US has shaped the modern world. One of the most powerful and enduring American ideas is that of the American Dream.
In this episode, Asma Khalid hears the story of one extraordinary American Dream seeker. The BBC first spoke to Abdi Nor Iftin in 2014, when he was living in one of Kenya's toughest neighbourhoods after fleeing conflict in Somalia. When he won the US green card lottery his problems seemed to be solved – but it turned out to be the start of a whole new struggle.
