Hi GetLucky8888,
Did you receive your PR yet? I applied for PR (June14th, 2019) when I was on active STEM OPT (ends in Feb 6, 2020).My F-1 Visa stamp ended in (July 19th, 2019) But I enrolled in a University and transferred back to F-1 status (Jan 6th, 2020) and working on full time CPT. My current PR processing time (Dec14th, 2019) has already gone and I'm still waiting for background and security checks. Do I need to update the CIC with this situation? Did you hear back from CIC regarding your case?
