“I came with my dad. I remember going from hotel to hotel. We would travel when it was really dark. We first went through Belize and through Mexico by bus. Today is great. It’s something we’ve been waiting for. It’s a new beginning.” KATERIN ZUNIGA, 19, a nursing student who came to the United States from Honduras at age 7.
