A message from Social Security:
Social Security Administration (SSA) offices at headquarters and the Baltimore Metropolitan area will be closed on Tuesday, March 14, 2017 [by a large snowfall]. ITC and Falls Church offices should continue to monitor and follow OPM guidance.
Somebody correct me if I'm wrong but I'll guess that ITC stands for the International Trade Center, a large government office building in Washington, and I'll also guess that's where the Commissioner's office is. I've never understood why it's better for the Commissioner's office to be there rather than in Woodlawn. There must be a fair amount of time wasted by staffers who have to travel into Washington for meetings at the Commissioner's office.
