Entry/Exit Requirements for U.S. Citizens
To enter Hong Kong, you will need a passport that is valid for at least one month beyond the date of your intended stay, adequate funds to cover your stay without working locally, and evidence of onward/return transportation. Many neighboring areas require that your passport is valid for at least six months before they will allow you to enter, so if you plan on regional travel beyond Hong Kong, make sure that your passport is valid for at least six months beyond the date you plan to enter such areas. You do not need a visa for tourist visits of up to 90 days. You may be granted an extension of your stay if you apply to the Hong Kong SAR Immigration Department. You must have an appropriate visa to work or study in Hong Kong. Visit the Hong Kong SAR Immigration Department or the Embassy of the People's Republic of China website for the most current visa information.
You should obtain all required visas prior to departing the United States. Specifically, if you wish to travel to the PRC from Hong Kong, you will need a PRC visa and should apply at the PRC embassy or consulate where you reside. If you are the parent of a child who holds U.S. passport, you should know that the PRC Visa Office may require a certified birth certificate or other documentation for your child. A certified U.S. birth certificated is generally required when applying in Hong Kong for PRC visas for U.S.-born children.
