Dear Sir/Madam,
Please allow me to introduce myself as Grace from Penang, Malaysia. I have applied for a China Visa to enter China using my present passport and has been approved to enter before 14 May 2011. Then I realised that I have made a mistake applying the visa using this passport.
It is because my present passport will expire in a year's time on 18 April 2011 and I will be going to enter Canada after I have visited China, not returning to Malaysia. So I need to apply for a new passport now before I leave Malaysia because I am required to stay in Canada for 2 years upon entering the country to fulfill my PR requirements, before I can come back to Malaysia later. Therefore, I must apply for a new passport now, ahead of time before I leave Malaysia to visit China on 9 April 2011.
Please let me know whether I can enter China in April 2011 with a new passport (need to make one as soon as possible) together with my approved China visa already on my previous (the present one with me) passport, which I will take along both passports together on the 9 April 2011. If I can still use the approved China visa which is on my present passport, then I will not have to waste money for another application of China Visa for my new passport.
Your kind valuable advice is most appreciated. Hope I can receive a quick reply from you.

Thank you very much,
Grace
