Possible for a British citizen with UK passport to obtain a Chinese visa from consulate in Chicago?

Dear Sir / Madam,

I am a British Citizen, with a UK passport, living in Chicago. I am due to visit China for one week in November, in order to perform a financial audit at one of my company’s subsidiaries located in Suzhou. However, I was wondering, is it still possible for me to obtain an entry permit from the PRC Consulate in Chicago, with a UK Passport?

Also, if I can obtain it, is it possible to obtain a 10-year one? Or is the maximum a 2-year type with multiple entries?

Many Thanks indeed for your help with this.

Best Regards,
Scott
