Hi Krunal,You cannot clims points for sibling until they finished their landing and signed COPR. Your sibling also must be living in canada after PR. If this is the case then you can update your EE profile and get ITA. You can show their signed Copr as proof of Status in Canada..
1) I created my EE profile on January 23rd with a CRS score of 442.
2) At the time of profile creation, my sister already had a COPR, but she was in India.
3) We received an ITA on 21st Feb.
4) My sister is flying to Toronto on the March 29th, 2018 and would be staying there.
5) She will send me all the relevant documents and evidence of address proof by 30th March.
6) We were planning to use those documents only when their PR would be active on March 29th.
So, what I hear is that I do not need to delete my current EE profile, just Decline the current ITA and resubmit once my sister lands in Canada?
