I can add something more to that. Had there been no filing date/final date introduction in 2015, CO would have advanced final dates for them in last quarter of 2016 or 2017 and all of them would have been greened before 2018. The non submission of medicals appears to be a big time visa waster this year. Last quarter and dates exceeded to what is being predicted for Eb2 and very close to December 2020 filing date.
