Hello everyone, I'm currently reviewing my Express Entry profile after ITA and right now I'm doing a lot of changes. The changes are the following: Removed 2 companies in my work history because I'm having a hard time getting a certificate of employment. I still have 5+ years of work experience under the same NOC with my remaining companies. Changed my primary NOC (it still has the same NOC Type, Type A) Removed all of my spouse's work history since we're not claiming points for that All our companies (including the ones we removed from work history) are captured in the Personal history section though. Would these changes (from pre-ITA) require a letter of explanation? Take note that I have not yet submitted the profile and I have not yet seen my personal checklist.
