The main purpose of the Open Doors to Diplomacy Act is to enhance the recruitment of candidates for the Foreign Service from nontraditional institutions of higher education. This includes schools like community colleges, junior colleges, and vocational or technical colleges. The goal is to diversify the pool of applicants for diplomatic roles and ensure that a wider range of educational backgrounds is represented in the Foreign Service. Key provisions of the Act require the Secretary of State to actively engage in outreach efforts at these nontraditional institutions.
