As long it is one year continuous work experience, you can use the NOC.Thanks for your response,
My secondary NOC is 7315 which related to type B and I have 7 years woke experience(ongoing). This NOC is regulated.
My primary NOC is 4161 .I have 3 years experience is related to type A, but in the next few months it will be out of 10 years and my work experience will be 2 years, that is under 3 years.
By considering this condition, can I writte Noc as a primary?
