My Qualification is BE in Computer Science and Engineering but currently working as piping Engineer in oil and gas industry from past 6 years. Am i applicable to apply for Canada PR due to mismatch. And I am not sure which NOC is applicable??
You can apply. Your education doesn’t have to match your work experience. As for the NOC, match your roles & responsibilities as close as possible that are outlined in your employment letter with the NOC you are considerin.
