As a Canadian Citizen going to work in my company's China affiliate office for two months, do I need a Z Visa or only a Business Visa? Also, do I get my Z Visa here in Toronto (asking my China inviter to send me the documents I need from China), or do I enter China on F Visa and then process Z Visa in China? Is the Z Visa the only document I need to work there? I believe I also need to apply for my residency permit once I arrive there, correct?
