An immigrant completes many requirements to become a U.S. citizen. The final step is to take an Oath of Allegiance. You promise to be loyal to the United States and give up loyalty to other countries. You promise to defend the Constitution and obey the laws of the United States. And you promise to serve the United States when the government needs your help.
