I submitted my profile and waiting for the ITA. I now have another job. Is the Certificate of Employment from my previous employer (the job that I declared on my profile for my application) needed to be dated in time I will have my invitation to apply or it doesn't matter the date on it (can be more than 6 months) from the date the manager sign it? Do I still need to attach a certificate of employment for my new work even if I will not use that (a proof I’m working)? Thank you.
