Craig Ferguson becomes an American citizen

29 January 2008 - The host of 'The Late Late Show' has taken his citizenship test.

The Late Late Show's Craig Ferguson had a perfect score when he took his American citizenship test.

He took the test last Friday but he won't officially be an American citizen until he is sworn in.

Ferguson told his audience on Monday night: "All of you people born here, if you had to take that test — well, Canada would be building a fence right now."

People.com reveal that Ferguson had to answer questions like "What month is the new president inaugurated?" and "Who is the chief justice of the Supreme Court?" to get full marks on his citizenship test.
