I am Canadian citizen. I have Bachelor of Economy(China) and 3-year accounting diploma (Canada).I get a job offer for Junior Accountant position today.

I call the immigrantion officer today, he told me that I should have CPA or CGA designation.But the professional list only require either Bachelor degree or CPA,CGA.
