Do you have to raise your hand?

Yes, applicants raise their right hand while taking the Oath of Allegiance. The raised right hand is the traditional gesture of oath-taking in U.S. legal practice, signaling that the speaker is making a solemn promise and inviting the legal consequences that follow from a false statement. Federal Rule of Evidence 603, which governs oaths and affirmations of witnesses in court, requires that a witness give an oath or affirmation "in a form designed to impress that duty on the witness's conscience," and the raised right hand is the customary form for both oaths invoking a higher power and affirmations made on conscience alone.

At naturalization oath ceremonies the presiding official (a USCIS officer or a federal judge) asks all applicants to stand, raise their right hand, and repeat the oath. The applicant should hold the right hand at shoulder height with palm facing forward and follow the words of the oath as they are read. The raised hand applies whether the applicant takes the oath "so help me God" or affirms the obligation without the religious phrase under 8 CFR section 337.1(b).

Applicants with physical limitations that prevent raising the right hand should notify USCIS in advance; minor accommodations such as raising the left hand or remaining seated with hand raised are routinely granted. The gesture has no separate legal effect; the legally operative act is the recitation of the oath. The raised hand is symbolic but is expected at virtually every U.S. oath ceremony. The raised-hand gesture is centuries old in Anglo-American legal tradition and remains universal at U.S. naturalization ceremonies today.
