The Family Liaison Office (FLO) acts as liaison with the Department of Homeland Security's U.S. Citizenship and Immigration Service (USCIS) in naturalization cases for foreign-born spouses of Department of State Foreign Service employees. The processing time and adjudication is under the sole authority of the USCIS.

Although the Family Liaison Office provides assistance to all Foreign Affairs agencies in other program areas, FLO's 319(b) naturalization assistance is limited to Department of State (DOS) spouses. Other Agency spouses should contact their Human Resource departments for possible assistance with 319(b) naturalization.
