The Immigration Department is a disciplined service under the Government of Hong Kong, responsible for immigration control of Hong Kong.
After the handover of Hong Kong to China in July 1997, Hong Kong's immigration system remained largely unchanged from its British predecessor model. Residents from mainland China do not have the right of abode in Hong Kong, nor can they enter the territory freely, both before and after 1997. There are different regulations that apply to residents of Macau, another Special Administrative Region of China. In addition, visa-free entry acceptance regulations into Hong Kong for passport holders of some 170 countries have remained unchanged since the 1997 handover to China.
