It certainly is possible but it was a big struggle for me. They didn't want to give it to us and after like 5 phone calls with my boss we managed to convince them to give us LMIA for at least 1 year (even though we applied for 2). Anyway, I was pretty pissed at my lawyer cuz she didn't try enough and told me to give up. Also, she told me that ESDC has numbers for each NOC code (like how many percent of LMIAs were approved under each code to give ESDC kind of a guideline if they need foreign workers for the NOC) She also had another client after the same NOC that got rejected but that was all last year so it might be different now. Anyway, if you can try to look for alternative codes. There's bunch of them that are pretty close to 1122 & 1123.
If Ontario start sending invitations after November 2016 for the people who are having more than 450 points do you think i will get the invitation for this noc code 1223 ..
