You can file a PCT application in China or file a patent application directly in the USPTO. Either way would work, as long as you file it within 12 months of your original Chinese national application. There are several differences/advantages/disadvantages in both methods. In US national filing, you would have to pay a local attorney in the US to handle the drafting and prosecution, which could be costly. Filing a PCT in China is easier but eventually you will have to enter the national stage in US. The main difference is that China Patent Office is not only a PCT receiving office but also a international search authority such that once China PTO conducts its preliminary search, the USPTO will defer to the search and MAY not conduct its own search again.
