Work experience and job offers

• There is no National Occupation Classification (NOC) code on my work permit. What should I put in my Express Entry profile?
• Can I count student work experience toward the Express Entry work requirement?
• I have been working in Canada for the last 6 months but didn’t get points for work experience. Why not?
• What if I am invited to apply for Express Entry while waiting for a new work permit?
• I was invited to apply through Express Entry but my work permit expired. What do I do?
• I didn’t get a Job Seeker Validation Code in the message you sent to my account. Why not?
