Hi Raj,
Thanks for your advise that was what I thought as well but the 10 years was what the CIC representative told me. So think I better submit as well.
1. So I've re-applied for my country of origin which I left in Sept'15 to come here. I have a PCC that's dated in Oct'15 but that's less than 6 months from today so I've re-applied.
What is your current country of residence? PCC for the current country of residence needs to be less than 6 months old at the time of submission of e-APR.
From what you are telling me, you are not in your country of origin at present and you have a PCC that was issued after the last departure from your country of origin. This PCC is valid.
2. I also have a PCC from another country which I lived in a few years during my uni days. That's dated in July'15. I've did go back there a couple of times just for holidays but have not stayed more than 6 months (a few weeks in total). Is this PCC still considered valid?
No, IMO. You need to get a fresh PCC.
Thanks
