For the secondary application, there is no point in adding foreign work experience in the Work History section as it will not give you any CRS points and you will be asked for job letters without any benefits. So, you should remove these 2 years from Work History section and only add them in the Personal History section and you will not need to provide any letters.
For the primary applicant, all you need is a letter(s) that covers all requirements which:
- should be an official document printed on company letterhead (must include the applicant’s name, the company’s contact information [address, telephone number and email address], and the name, title and signature of the immediate supervisor or personnel officer at the company),
- should indicate all positions held while employed at the company and must include the following details: job title, duties and responsibilities, job status (if current job), dates worked for the company, number of work hours per week and annual salary plus benefits.
So, if all the above information is covered in your documents, you should be fine. The Notice of Assessment, paystubs, offer letter, etc. are all supporting documents and are
not mandatory as long as you provide a Reference Letter from your employer that covers all information above. Good Luck!
