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 patriotism and loyalty 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.
