For years, Maricopa County, Ariz., has been ground zero in the debate over immigration.
On one hand, the massive county, which includes the state capital of Phoenix, has a growing Latino population. On the other, it's home to publicity savvy Sheriff Joe Arpaio, who has made his name by strictly enforcing, some say overstepping, immigration laws.
Eleven-year-old Woosuk Kim sees his mother only three or four times a year. That's because he's part of what Koreans call a "goose family": a family that migrates in search of English-language schooling.
A goose family, Woosuk explains, means "parents — mom and dad — have to be separate for the kids' education."
Woosuk's father brought him and his little brother to America two years ago to attend Hancock Park Elementary, a public school in Los Angeles. The boys' mother stayed in South Korea to keep working.
