The Mexican Barbie is from Mattel's new "Dolls of the World" series.
The doll comes complete with a fiesta dress and a Chihuahua dog tucked under her arm -- and a passport.
Some Mexican journalists are mocking the doll. One said, "Play with your Barbie Mexicana and don't even think of calling her undocumented."
A Mattel spokeswoman says the Barbie was created to help foster learning and appreciation of different countries and cultures.
