Thank you for contacting the Saskatchewan Immigrant Nominee Program.
Your application was referred to and has been put in the queue of the SINP Program Integrity Unit (PIU) for further review. Please be advised that this review may take an extended time and in the review the PIU does not provide status update or respond to any status inquiry. If additional information or if any 3rd party (e.g. your education institution, employers) verification is required, you or the 3rd party will be contacted.
Once this review is complete, your application may be returned to resume eligibility assessment, or concluded by the PIU in which case a decision will be communicated to you.
