Pase de un Día

A Writers of the Future honorable mention
Chalo had a chance to work hard and build a better life for his family. As a lucky holder of a pase de un día, a day pass, every morning he could teleport from his impoverished town in Mexico to a job in the United States.
A billion other people from the world's poor countries wanted his job. But they could only get it if he didn't teleport home before the final second of his 12 hour shift.
Or if he lost his day pass.
