Katie Couric's Notebook: Citizenship

Hi, everyone.

What do you have to know to become a U.S. Citizen?

After six years -- and six and a half million dollars -- the government has overhauled the application process -- including the test for citizenship.

Instead of knowing the number of states or Supreme Court Justices, new Americans will have to know, among other things, why we have three branches of government, and name one important idea in the Declaration of Independence.

In short, they'll have to know less of the what and who -- and more of the why and how of America.

I don't know if these new questions are an improvement. Certainly, they're more challenging.

But how many Americans who were born and raised here are able to answer those questions? Maybe we should all renew our citizenship the way we renew our driver's license, so we can all remember the driving principles on which our country was founded.

That's a page from my notebook.
