When an immigrant takes the oath to become a United States citizen, a certain kind of responsibility is taken on by said person. This person chooses to leave behind all other national allegiances, and chooses to take on the rights and responsibilities of a United States citizen.
This decision is not one that can be easily put into action, and millions of people have chosen to take this path over the last decade, take on the paperwork and time to become assimilated into the greatest nation on earth.
The climax of the process is taking the oath of citizenship. This is the point where an individual becomes a full-fledged member of American society. For anyone going through the process, it is a momentous occasion.
