Here is President Obama’s FY2010 budget (pdf). The funding highlights for the State Department are in pages 87-89 including the following.
Expands diplomatic and development Operations. This initiative will strengthen the U.S. Government’s diplomatic and development operations to support our national security. The 2010 Budget includes funding for the first year of a multi-year effort to significantly increase the size of the Foreign Service at both the Department of State and the U.S. Agency for International Development (USAID). An increased cadre of State and USAID Foreign Service officers will help advance our critical foreign policy goals and deliver on our expanding U.S. foreign assistance commitments.
Note that this does not indicate how many additional positions are requested. In the past, the president has indicated an increase of 25%. AFSA president, John Naland was recently in this Government Executive piece:
John Naland, president of the American Foreign Service Association, said details on the proposed workforce expansions -- expected in April when Obama unveils his full budget request -- would put other staffing increases in context. The 2009 omnibus spending bill, which funds 500 State Department positions and 300 new jobs at USAID, is a "good start" in addressing shortfalls, he said, "but we do not know yet what will be contained in the fiscal 2010 budget request."
