Inside the immigration office in Tel Aviv, Yohannes Tesfagabr considered his options. He could not return to Eritrea, a country he risked his life to flee in 2010. He hoped to avoid the fate of compatriots who languished in a desert jail for illegally staying in Israel. So in an emotional decision last November, the 29-year-old accepted what Israeli authorities were offering: $3,500 and a one-way ticket to Uganda or Rwanda. Two weeks later he was on a flight to Uganda.
