I dont think you need a PCC to submit an EE profile. You will need to provide the PCC after you get an ITA.
I had successfully submitted a EE profile CRS 454 in Dec 2017. Got ITA and submitted docs. The application was rejected since my PCC was expired. Was asked to file a fresh EE.
Tried submitting a new EE profile today but the system says that my "profile is ineligible". IELTS score expires on 20 Feb 2018.
Don't know what's wrong.
