Brunei Permanent Resident holding ICI passport

(1) Cayleen, you need to get two visas to visit HK and Macau respectively. The required documents for the two visas are almost the same including copy of your passport, the application form and a passport-style photo, proof of your financial support, hotel reservation, transportation arrangement, and your travel itinerary.
(2) It costs HKD 190 for HK tourist visa. As for Macau visa, it’s possible for you to get VOA and it costs MOP 100.
(3) Usually, the stay duration of tourist visa is 30 days, so you can stay for 30 days in HK and Macau respectively.

Thank-you Blair for your kind and helpful information. Your feedback has assisted me in knowing the necessary requirements for the visas application.
