Foreign Service Consular Fellows serve in U.S. embassies and consulates overseas alongside Foreign Service Officers, other U.S. agency personnel, and locally-employed staff. Using their language skills in Spanish, Portuguese, Mandarin Chinese, Arabic, Russian, or French, their primary duty is to adjudicate visas for foreign nationals. Duties and responsibilities are similar to those of entry-level career Foreign Service Officers. While at post, Consular Fellows are members of the embassy or consulate community and receive many of the same benefits that career Foreign Service members receive, such as housing and educational allowances for eligible family members.
