Thanks this really helps... Can I submit the SINP application without submitting my EE as I'm still awaiting for WES.
Also, in the second screen there is an step of work permit? What I need to fill in there as I don't have any work permit. Shall I just leave it blank?
Without an EE profile, the only option (other than a job offer from a Saskatchewan employer) is to apply through the OID subcategory.
The Work Permit is part of the pre-application set of screens, and should not appear if you do not have any work experience in Canada. I believe they are really interested in substantiating any work experience in Saskatchewan, because they give you points on their 60-point grid for previous work experience in the province. However, should you have work experience in Canada that you will use to obtain points for the work experience portion of the grid, you should definitely provide the IMM 1448, since this will show the employer for which you will provide the employer reference letter, and leave them no doubt.
For the EE profile, however, you need not have an ECA, so long as you score at least 67 points on the selection grid. the ECA will give you points on the CRS score for your education, but, you need not obtain a minimum CRS score to remain in the EE pool, only the 67 points. Even if your CRS score were zero, with a provincial nomination, you will obtain the requisite number of points for most every ITA draw, as the minimums have mostly been in the mid 400's range.
For the SINP, there is no need to have an ECA, as it is transcripts and diplomas that they require to substantiate your education, and not an ECA. Certainly, if you have an ECA, you can submit it in addition to the transcripts to better prove your education and to eliminate doubt for the examiners, but you should not submit an ECA alone, as their instructions require the transcripts and diplomas. Even with an ECA, they will likely deem the education substantiation documents to be missing, and return the application without returning the fee.
