Good day,
Thank you for contacting Immigration, Refugees and Citizenship Canada. As discussed, you will find below complementary information to our conversation:
Invitation to apply - How IRCC calculates the one year work experience
When submitting an Express Entry (EE) permanent residence application, you must demonstrate you are meeting the
eligibility requirements of one of the federal economic immigration programs. One of the requirements is to enter the month/year of work experience and no specific date. Therefore, you may have received an Invitation to Apply (ITA) even if you are missing a few days of work experience to be eligible.
IRCC officers processing the EE applications are aware of the system calculating months and not actual days/hours worked in a month. When reviewing an application, they will take into consideration factors such as:
- Continuous work status,
- The Offer of Employment Letter from the same employer, and
- Whether you reach the one year work experience at the time the EE application is submitted/approved or within a few days after.
The decision for approval is at the discretion of the officer. However, the onus is on you to provide all required information and supporting documentation to facilitate the decision.
