Since the end of last year, I have never worked for the U, I have never done anything for the U, I have never been the U, and I have never submitted any timesheets to the U, therefore I have quitted in effect long long time ago. The U should have withdrawn the H-1B long long time ago. As I right?!
-THen, you are fine! You do not need to show up to meet the IO and just tell the HR of that University to inform the IO that you have never worked there. That is all.
