Passport validity requirements

Your passport must be valid for at least one month after the date you plan to leave Hong Kong.

Check with your travel provider that your passport and other travel documents meet requirements. Renew your passport if you need to.

You will be denied entry if you do not have a valid travel document or try to use a passport that has been reported lost or stolen.

When returning to the UK, British citizens must carry a valid British passport or certificate of entitlement. See Dual citizenship.

Other types of British nationals who are exempt from ETA must also carry a valid British passport when entering the UK.

Visa requirements

Hong Kong is part of the People’s Republic of China, but it is a Special Administrative Region (SAR) with its own immigration controls.

You can visit Hong Kong for up to 6 months without a visa. For information on entry requirements see the Hong Kong SAR government website.

To stay longer, to work or study, for business travel or for other reasons, you must get a visa. For further information contact the nearest Chinese mission with visa issuing facilities or the Hong Kong Immigration Department.

Risk information for British companies

The Overseas Business Risk guidance offers information and advice for British companies operating in Hong Kong on how to manage political, economic, and business security-related risks.

Dual Chinese-British nationality

Hong Kong does not recognise dual nationality, and does not recognise the BN(O) passport as a valid travel document or proof of identity. If you hold both British and Chinese nationality, local authorities may treat you solely as a Chinese citizen, even if you enter Hong Kong on a full “British citizen” passport or hold a British National (Overseas) passport. In such circumstances, the British Consulate-General may not be able to offer you consular assistance.

If you have formally renounced Chinese citizenship, carry evidence that you have done so.

See guidance on nationality in China.

Laws and cultural differences

National security laws

The 2020 National Security Law (NSL) includes offences such as:

• secession
• subversion
• organisation and perpetration of terrorist activities
• collusion with a foreign country

The 2024 Safeguarding National Security Ordinance includes offences such as:

• treason
• sedition
• unlawful disclosure of state secrets
• external interference endangering national security

National security laws can be interpreted broadly and some offences can lead to a maximum penalty of life imprisonment. Individuals and organisations can be prosecuted and are required to comply with national security investigations, including sharing full access to electronic devices.

The national security laws apply to activities taking place inside and outside Hong Kong, including in the UK. The national security laws apply to all individuals regardless of nationality or residency.

Hong Kong’s National Security Police have issued arrest warrants and financial rewards against individuals living outside Hong Kong, including in the UK under the 2020 National Security Law.

You could be detained or removed to mainland China for some offences under the 2020 National Security Law.

Criticising the government

Some people have been prosecuted for publishing or supporting statements that are critical of the Hong Kong or Chinese authorities, including online. You could also be prosecuted for supporting individuals who are considered to be breaking national security laws.

Immigration Ordinance

The Immigration (Amendment) Ordinance came into force in 2021. Under this law, people could be stopped from leaving the Hong Kong Special Administrative Region (SAR). However, the Hong Kong SAR government has said these powers will only be used to stop certain asylum seekers from entering Hong Kong.

Public offences

You can get on-the-spot fines for littering, jay walking or spitting.

Wildlife, animal products and souvenirs

It is illegal to import and re-export elephant ivory and its products, including tourist souvenirs. You could get a fine or prison sentence.

Illegal drugs

Avoid any involvement with illegal drugs, including cannabis. All cannabis products are illegal in Hong Kong, including CBD (cannabidiol) items such as oils, creams, capsules, and food products.

Criminal gangs and individuals in the UK and overseas have been known to coerce people into carrying drugs.  Do not allow yourself to be persuaded.

Hong Kong enforces a zero‑tolerance policy toward dangerous drugs and will not tolerate drug‑related activities. If you are found guilty of smuggling, trafficking, possessing, or using illegal narcotics, including while transiting through the airport, you should expect a severe prison sentence.

Airports in Hong Kong have excellent technology and security for detecting illegal items. This is also used to scan the baggage of transiting passengers.

Taking photographs in secure areas

Do not take photographs of military installations.
