Letter of employment is for your current job detailing how long you’ve worked for the company and all the needed details by IRCC. You don’t need to upload your job contract for that.Another question from my side.
I have a job offer and i'm already working in this position being offered.
I have signed a contract. This job contract would be the "offer of employmet" or the "letter of employment"?
offer of employment is for a future job, if you claimed 50 points.
- be recent (usually less than 1 year old)
- You can’t use the same job offer letter that you used to get your work permit.
