Dear Altruists Can I update my employment reference letter after submiiting express entry application and paying the fees.I mean after getting AOR. The employment letter I submiited was from my university's former head of the department.Now the head of the department has changed. Moreover,the current head of the department has given me an updated employment reference letter with more precise details of the Job Duties. Is there a way i can upload this document now? And if I can update it, will it delay my application processing time? Thanks in advance.
