The inventory was approximately 5,000 cases. The thinking at the time was to put together a special task force to deal only with the legacy cases, and the IRB was able to do that. They put together a legacy task force. They posted information publicly that suggested they could get through the legacy backlog in two years.
Obviously that doesn't mean that everyone will be processed in two years; some peoples' hearing will be even earlier than that. They also anticipate some of those cases will not be considered because they would either have been withdrawn by the individuals involved or would be regularized in some other fashion, through spousal or something like that.
As of October 31, 2017, the legacy backlog had 4,917 cases. That's a drop from the original number, which was around 5,600 people.
