Oath of citizenship

An Oath of Citizenship is an oath taken by immigrants that officially naturalizes immigrants into citizens. It is often the final step in this process, and is usually done in a ceremonial capacity. An oath of citizenship is designed to be a statement of loyalty and patriotism to the new country. In countries which retain a monarchical system of government, an oath of allegiance to the monarch is often required as well. Adding an oath to God to the end of an oath is usually optional.
