For many years Turkey has banned female students from wearing the headscarf - or hijab - in school.  To get around the ban, some Muslim girls and young women have left Turkey to attend high school and college in the U.S. and other countries where they are permitted to cover their heads in the classroom. Turkish television journalist Necla Demirci tells the story of two sisters, Sumeyye and Safiye Sideli, who came to New York as teenagers to complete their education.   In her conversation with Fi2W Executive Producer John Rudolph, Demirci also speaks with Mucahit Bilici, assistant professor of sociology at John Jay College, who studies Islam in America.
