BTW what does OTR and VSU stand for? OTR i am guessing is on the record?
but VSU I have no clue
You are correct that OTR is on the record. VSU is virtual screening unit.
From an older document but it has a description:
"We are building upon the success of our senior attorney adjudicators this fiscal year by deploying a Virtual Screening Unit (VSU) of 100 senior attorney adjudicators to assist our most heavily backlogged hearing offices. These senior attorney adjudicators who are from hearing offices throughout the country screen electronic cases and write favorable decisions that result from the screening. The VSU started screening cases in November 2009 and went into full production in January 2010. So far, the VSU has screened 19,547 cases and issued 5,757 favorable decisions, while referring 239 cases to ALJs for favorable decisions. The VSU's work has resulted in fewer remands to the already burdened DDSs. The VSU has assisted 43 hearing offices."https://www.ssa.gov/legislation/testimony_042710.html
