The Basic Law (BL) is the constitutional document of the Hong Kong Special Administrative Region (HKSAR). Put into effect on July 1, 1997, it enshrines within a legal document the important concept of “One Country, Two Systems".
Q: Is Hong Kong an easy place to visit for tourists or international business people?
A: Yes, very much so. Hong Kong has autonomy in immigration control. It maintains its own immigration laws and procedures and has a very liberal visa policy. As of September 2018, 162 countries or territories have granted visa-free access or visa-on-arrival to HKSAR passport holders. (BL Articles 154; 155)
