I applied with my travel agent for a one year multiple entries Chinese visa in 24Feb2009. I plan to visit China again in October, 2009 but I may have a problem since the visa says that I must begin enter by 24Aug2009. What is the validity period of this visa? Is this visa good for one year? If so, why do I have to enter by 24AUG2009? How do I go about correcting the validity period of this visa? Please advise. Thank you.
