Yes,
Yes, you are right. I do have a one-year job offer from the employer. But can you tell that this 1-year offer starts from which day? It should be 1 year from the day I submit my application in the pool, or from the day I get my ITA? I have seen somewhere that it should be 1 year after getting the PR. Which one is the correct?If you are claiming points for the job offer, it needs a written offer from your employer.
Work Permit is not a job offer, however, it is one of the document that you "may be required to attached, showing until how long your WP is valid.
Be very careful with this job offer document and ensure it covers all the points required by IRCC for claiming job offer points, as case officers scrutinize this quite a lot and have seen a lot of rejections in the past.
I had claimed points for job offer myself and I did submit all the required documentation for it.
