The Family Liaison Office (FLO) acts as liaison with the Department of Homeland Security's U.S. Citizenship and Immigration Services (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 FLO provides assistance to all Foreign Affairs agencies in other program areas, its 319(b) naturalization assistance is limited to Department of State spouses. Other agency spouses should contact their Human Resource offices for possible assistance with 319(b) naturalization.
