where exactly could I ask for for visa to HK? Thanks

Hey, you should go to the HKSAR Office in Beijing to submit the application documents, which include your passport, a copy of the passport, an application form, a passport-styple photo taken within six months, a photocopy of your financial background status, a photocopy of your PRC residence permit, round-trip transportation tickets to and back from HK, and other supporting documents based on your travel purpose.
