Oath of Allegiance Law and Legal Definition

Oath of allegiance is an oath by which a person promises to maintain fidelity to a particular sovereign or government. This oath is mostly administered to a high public officer, to a soldier or sailor or to an alien applying for naturalization. In the U.S., a person takes an oath of office that includes swearing allegiance to the U.S. Constitution. It is also termed as loyalty oath.

The following is an excerpt from a federal statute on oath of allegiance.

An applicant for naturalization must establish that it is his/her intention in good faith to assume and discharge the obligations of the oath of allegiance. [8 CFR 337.1]
