Law school with a foreign undergrad degree?

So I'm in high school now in the US, but my parents want to move to India once I graduate. I'm planning on attending law school in India, which is 5 yrs (no undergrad.) However, I don't want to practice in India, and I would like to return to the US. Would I have to go to school and complete the entire 7 years again, or just law school? Or could I go right into practicing? Which is probably unlikely given the differences between the American legal system and that of India. I just need a general outline of how I need to plan the next 10 years.
Thanks.
