When naturalized citizens take the oath of allegiance the phrase so help me god may be excluded under what circumstance?

Naturalized citizens may exclude the phrase "so help me God" from the oath of allegiance if they have a religious or personal objection to its inclusion. This allows individuals who adhere to non-theistic beliefs or who do not wish to invoke a deity to still participate in the naturalization process. The U.S. Citizenship and Immigration Services (USCIS) permits this accommodation to ensure that the oath respects the diverse beliefs of all citizens.
