Yes at this point I guess we can only wait. I really hope everyone who has been waiting gets their PPR soon.Hey,
I'm 4th Apr AOR and in a similar situation. My eligibility is still under review as my current Canadian employment reference/offer letter doesn't clearly state that I will have arranged employment for one year. The case analyst put it as review required even though I have a valid work permit till 2019 Dec. This was way back on 11 Apr mind you (according to my GCMS). Since then, I have been waiting patiently. I called CIC yesterday and got the same reply as you. I know the wait is excruciating, but believe me, thinking and worrying about it is to no avail.
Also, understand that even October may not bring you any news. There are way too many people beyond their 6 months still waiting. I guess you know what I mean.
