On a recent Saturday morning in South Florida, 50-year-old Edgar Ospina stood in a long line of immigrants to take the first step to become an American.

Ospina has spent almost half his life in the U.S. after emigrating from his native Colombia, becoming eligible for citizenship in 1990. But with Donald Trump becoming a more likely presidential nominee by the day, Ospina decided to wait no more, rushing the paperwork required to become a citizen.
