I have a dilemma. I have a Canadian Passport (Canadian borned) with China visa (going for business). However, in the meantime I just obtained US citizenship (I reside in USA and gave up my green card during oath). So I have will have 2 passports, Canadian with China visa and a blank USA Passport.

I plan to fly into Hong Kong and bus/walk into Shenzhen, China. Vis versa coming back home (USA). Will this be possible with Canadian passport to get into China showing Canadian passport exiting USA? I'm trying to avoid getting another Visa due to time and cost. Also, if someone can advise when I should use/show which passport and which passport to put onto airline ticket. Thank you in advance for your help.
