If you'd like to celebrate Presidents' Day by learning more about the powers of the President, a good place to start might be this page of resources from U.S. Citizenship and Immigration Services:
information is provided to help immigrants prepare for the 18 questions
on the naturalization test that deal with the Presidency. There's even a
10-question practice test on the site that you can take. Be brave and
see how many you're able to answer correctly.
