(Updated 10/26/23) U.S. Secretary of State Antony Blinken inaugurated a 200,000-square-foot building at the Arlington-based National Foreign Affairs Training Center yesterday.

The $121.2 million, federally funded facility, dubbed “Building B,” opened in 2022. It aims to expand the training center’s capacity, which has seen a surge in recruitment over the last two years, according to State Department officials.

“Building B has vastly increased the Foreign Service Institute’s workspace, creating hundreds of new areas where students and instructors can come together for classes, breakout sessions, large format meetings,” Blinken said during the dedication ceremony on Monday.

Located on S. George Mason Drive in the Alcova Heights neighborhood, the training center is the primary training ground for U.S. diplomats and foreign affairs professionals, offering courses in languages and international relations.

Since 2020, the student body has increased by nearly 30%, said Joan Polaschik, the director of the Foreign Service Institute.

“We are engaged in the largest hiring surge in more than a decade,” she told ARLnow following the ceremony.

This surge forced the training center to use State Department offices in Rosslyn to accommodate the overflow of students, according to FSI.

The State Department has seven other buildings in Arlington, home to bureaus such as Diplomatic Security and the Office of the Inspector General. More than 5,000 full-time employees and contractors work across these offices.

The new Building B, which serves a total of 3,679 in-person and online students, should alleviate this overflow issue, according to FSI. The campus has seen its daily in-person student capacity increase by 25%, going from 650 to 1,100.

Building B is home to FSI, the Consular Training Division, School of Professional and Area Studies and Leadership and Management School.

“The new Building B will eliminate the need for both of these spaces in Rosslyn and consolidate language studies in one place — our Arlington campus,” the FSI spokesman said.

Other planned expansion efforts resulted in the closure of a walking trail, despite efforts from some residents to save it, though these were unrelated to Building B, the spokesman later clarified. Plans for Building B were approved in 2020.

During his remarks, Blinken — who lives in Arlington — said the new building serves as a much-needed asset, amid growing tensions between the United States and other global superpowers, such as Russia and China, as well as conflicts in the Middle East between Israel and Palestine.

“It is essential that we empower our workforce with the skills and training that they need to operate in a crisis like this and to meet any challenge that comes our way,” he said. “So today, I’m really happy to mark the significant step forward toward that mission.”


Unanswered questions remain after a security contractor was killed at the U.S. State Department’s National Foreign Affairs Training Center in Arlington.

The incident happened the evening of Tuesday, Nov. 16, at the 65-acre campus near the intersection of Arlington Blvd (Route 50) and N. George Mason Drive.

Arlington’s 911 dispatch center received multiple calls shortly after 6 p.m. for a pedestrian struck on the P2 lot of the campus. Callers were asked to start CPR on the victim, who was then rushed via ambulance to Virginia Hospital Center in cardiac arrest, according to fire department radio traffic.

The exact circumstances around who struck the victim and with what type of vehicle remain unclear. The dispatches reference a large amount of blood on the scene.

Arlington County police and fire department spokespeople deferred comment to federal authorities.

The State Department confirmed that the victim, a security contractor, died.

“We can confirm the death of a uniformed protection officer (UPO) with the Diplomatic Security Service (DSS) on November 16, 2021,” a spokesperson said in a statement, in response to an inquiry from ARLnow. “The officer was assigned to the National Foreign Affairs Training Center in Arlington, Virginia. The officer was a contractor whose job duties included domestic facilities protection. The Department of State extends its deepest condolences to the family and loved ones of the deceased.”

The State Department’s Diplomatic Security Service arm, which is based in Rosslyn, is leading the investigation.

“We do not comment on ongoing investigations due to privacy and law enforcement sensitivity considerations,” the State Department spokesperson said. “There is no further information we can provide at this time.”

The spokesman did not respond to a question seeking more clarity on what exactly happened.

ARLnow is told that the contractor who was killed was a 22-year-old former high school football player from Waldorf, Maryland. His funeral was held earlier this month.

The National Foreign Affairs Training Center is one of several locations of the Foreign Service Institute, which trains U.S. foreign affairs personnel.
