The Comprehend Ranking System (CRS) score is of immutable importance when applying for the Canadian Federal Express Entry, regardless of the program.
In order to be given an Invitation To Apply (ITA), your CRS score must meet the threshold eligibility requirement for that particular pool. The total points are 1,200.
The general rule of thumb is that a score of 470 is a good score, however this varies depending on the score distribution of the applicants of a given pool.
Thus, your safest bet as an applicant is to leverage on all options to boost your score.
One way to boost your score is by having a sibling in Canada who is legally resides as a Permanent Resident on citizen.
Note that having a sibling who is on a study permit does not apply in this context.
Also, if your spouse / common-law partner who is featuring as a dependant in your application has a sibling in Canada who is a citizen or permanent resident, this could also boost your CRS score.
Leveraging on this option is contingent on providing proof of the nature of the relationship. The relationship could be through
4. Common-Law Partnership
This could effectively boost your CRS score by 15.
