1) The fastest way to get from is from the HK airport.
China Travel Service (HK) (CTS) visa issuing offices at Hong Kong International Airport offer a fast and convenient way to get a Mainland China visa.
Passengers can get their Taiwan resident re-entry visas, officially known as "Mainland Travel Permits for Taiwan Residents", in about an hour. For other China visas, it takes about five to six hours. However, the processing time for certain cases may be longer. Please contact CTS for details.
The CTS office in the restricted area handles visa applications for Taiwanese residents only, while the counter in the non-restricted area processes all types of China visa applications.
