I saw a case in this forum who submitted their application in Feb 2018. got interviewed in March 2018 (Chicago office) and got approved 15 months after the submission date. So, even with the new LIFO system, you might still have to wait for over a year.It seems we are both in the same situation. My application was submitted October 2018 and interview conducted in November 2018 at the same Chicago office. Till date i havent received any response. Its really annoying waiting dis long even with their so called new method.
