Constitution Day and Citizenship Day is a combined event that is observed in the United States on September 17. This event commemorates the formation and signing of the Constitution of the United States September 17, 1787, and celebrates our American citizenship. What a great day to fly the American flag!
For an excellent overview of our Constitution see this article at the National Archives.
Citizenship Day, one of our newest federal holidays, was established and ratified by Congress on 2004. It recognizes all who, by coming of age or by naturalization, have become US citizens.
“I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I will bear arms on behalf of the United States when required by the law; that I will perform noncombatant service in the Armed Forces of the United States when required by the law; that I will perform work of national importance under civilian direction when required by the law; and that I take this obligation freely without any mental reservation or purpose of evasion; so help me God.”
In some cases, US Citizenship and Immigration Services (USCIS) allows the oath to be taken without the clauses:
“… that I will bear arms on behalf of the United States when required by law; that I will perform noncombatant service in the Armed Forces of the United States when required by law … “
If USCIS finds that you are unable to swear the oath using the words “on oath,” you may replace these words with “and solemnly affirm.” If USCIS finds that you are unable to use the words “so help me God” because of your religious training or beliefs, you are not required to say these words.
