** LEGAL UPDATE **
Among the tests you will need to pass to become a U.S. citizen through the process known as naturalization is one covering U.S. civics and government.
The good news is, U.S. Citizenship and Immigration Services (to which you'll apply for citizenship) provides a list of the 100 possible questions. You don't have to memorize all 100 answers, just enough to get six out of ten correct.
As of January 19, however, there's an important update to this news: A few of the answers you'll need to supply to the 100 questions have changed, depending in part on where you live and who won recent elections in your state.
Specifically, some questions having to do with names of members of Congress and state governors might have new answers, which you'll need to commit to memory. The questions are:
For the first three of these questions, you will need to look up the answer. Here's a list to help you find the name of your state's senators. For your representative, go to house.gov. And your state's governor's name can be found on USA.gov.
As for Speaker of the House, that is now Nancy Pelosi.
