My HKSAR Passport will be expired by November 2017.

Hi, first, make an online appointment for the application.
Prepare your passport and its copy, a completed application form, and 2 passport-style photos, HK ID card, residence permit in the US, as well as other documents the consular officers consider necessary, and then submit the application to the consulate where you resides.
You need to pay USD67 to HKSAR government for 32-page passport and USD15 to the embassy of China as communication fee. Besides, you also need to pay the postal fee and you can inquire about that with the office workers.
