They need reference letters from all of previous employers, first month and last month pay slip which will be very difficult to get. Basically, you need to prove all of your work experiences in your primary NOC and not just partial or the one's you claim in your EE profile.
Thank you. My primary NOC is 0213 for which I have claimed 2 years of experience( this is the one I only have experience letter for + some irregular payments). For my second NOC(2175), however, I have claimed 20 months of experience (I can prove this with enough documents). So, is it possible to change my primary NOC to 2175 for which I can show enough documents? Or it will raise questions as to why I have changed my EE profile after receiving NOI?
