The amount of federal employees attending conferences had dropped by as much as 90 percent since last year, Graham added.
While workers should not view sequestration as imposing a "moratorium" on travel expenses, they should expect a "continued reduction in conference and travel activity" while the cuts are in effect, the OMB says in the new guidance.
The new notice is similar to a memorandum from the Office of Government Ethics released in recent weeks.
The OMB alert pushes agencies to look for cheap airline tickets and use "no-frills" services when sending workers to conferences, and directs them to investigate videoconferencing if possible.
Agencies must file reports to an inspector general on conference trips that cost employees over $20,000.
Conferences that cost over $100,000 need approval from deputy secretaries, and those over $500,000 need the go-ahead from the agency head.
