Hi Misro,
First of all Congratulations, you are just a few steps away from applying to SINP.
Check SINP process here
https://www.saskatchewan.ca/residents/moving-to-saskatchewan/immigrating-to-saskatchewan/saskatchewan-immigrant-nominee-program/international-skilled-worker-eoi-system
1. We need to raise EoI -- Expression of Interest, You are here, which means you are telling Saskatchewan that you are interested in migrating to Saskatchewan. Here you need to tell them basic details like JOB code, EEProfile number, years of experence etc., Here you don't need any documents. Your score will be calculated based on our profile.
2. You interest will be placed in pool with score
3. SINP will select applications based on scores and will send an invite to apply(ITA)
4. Once you receive ITA, will have 60 days time to submit along with documents
5. SINP team will validate application aganist documents and makes decision
So do not worry about documents/ screens now, it will come at step 4. However, I suggest you to be prepared with all the required documents and be ready.
Good Luck !
Regards,
Bhoomica
