Hong Kong International Airport (HKG) is a major hub for travellers, but the rules for transiting passengers can be confusing. For US citizens travelling on Cathay Pacific, no paperwork is required, and passengers simply need their onward boarding passes to go through transit security and proceed to the departure gate. However, for those travelling on other airlines, there may be different requirements. Some sources suggest that passengers can choose between going to transfers or immigration, but it is not always clear which option is available, and there may be additional requirements for entering the HKSAR during transit. HKG also has strict security regulations, including enhanced screening for liquids, and passengers are advised to allow extra time for this.

US citizens don't need a visa to transit through HKG
US citizens do not need a visa to transit through Hong Kong International Airport (HKG) as long as they have a valid passport and their stay is less than 90 days. This is because US citizens are covered by the visa waiver concession for the Hong Kong Special Administrative Region (HKSAR).
However, it is important to note that there may be additional requirements or restrictions depending on the specific circumstances of the transit. For example, if a US citizen is travelling on an active duty military passport, different rules may apply. It is always recommended to check with the relevant embassy or consulate for the most up-to-date and accurate information regarding visa requirements.
Another important consideration is that US citizens travelling through HKG may be subject to scrutiny from local law enforcement. It is mandatory for all travellers aged 11 and above to carry their passports with them, as police have the right to detain anyone who cannot present their passport. Furthermore, Hong Kong has strict regulations regarding controlled items, and luggage is thoroughly screened before being loaded onto aircraft.
In addition, since the imposition of the National Security Law in 2020, the People's Republic of China (PRC) has targeted a broad range of activities that it classifies as secession, subversion, terrorism, and collusion with foreign entities. As a result, US citizens who have been publicly critical of the PRC or the Hong Kong administration may be subject to a heightened risk of arrest, detention, expulsion, or prosecution under local laws. Therefore, it is essential for US citizens transiting through HKG to be aware of these potential risks and to comply with all local laws and regulations.
Overall, while US citizens do not need a visa for transiting through HKG, it is important to stay informed about the specific requirements and potential risks associated with travelling through Hong Kong.

HKG has strict security regulations and enhanced screening for transfer passengers with liquid items
Hong Kong International Airport (HKIA) has implemented strict security regulations that are in line with the International Civil Aviation Organization (ICAO). These regulations are in place to ensure a safe flying experience for all travellers.
HKIA has specific regulations regarding liquid items for transfer passengers. As of 13 August 2018, all transfer passengers travelling with liquids, aerosols, and gels (LAGs) contained in tamper-evident sealed plastic bags are required to undergo enhanced security screening using specialised LAGs screening equipment. This may include removing the LAGs from the sealed plastic bags for screening. Passengers are advised to allow extra time for this screening process.
For transfer passengers carrying liquid items purchased at shops beyond the security screening checkpoints, different regulations may apply. Passengers travelling to the United States or Australia or those transferring to another flight at the next port of call should check with their airlines regarding the requirements for carrying liquid purchases. Generally, liquid items are permitted if they are in containers no larger than 100ml and placed in a transparent re-sealable plastic bag with a maximum capacity of 1 litre.
It is important to note that medications in LAG form are exempted from the 100ml requirement. Passengers are allowed to carry essential medicines in sufficient quantities for the flight. However, to facilitate the screening process, it is recommended that LAG form medications under 100ml be placed in the 1-litre transparent re-sealable plastic bag along with other liquids. If the medication container exceeds 100ml, it should be presented separately to security for x-ray inspection, and verification for the product may be requested.
In addition to the liquid item regulations, HKIA also has standard security measures for all passengers. Electronic and metallic items in hand baggage or on the person should be placed in a separate tray for security checks. Passengers departing for the United States may be subject to additional security measures on electronic devices as required by the U.S. Department of Homeland Security.

HKG has a low crime rate, but travellers should be cautious in crowded areas
Hong Kong International Airport (HKG) is known for its strict security regulations, which are in line with the International Civil Aviation Organization (ICAO) guidelines. These regulations are in place to ensure a safe flying experience for all travellers passing through the airport.
While Hong Kong, as a city, generally has a low crime rate, travellers should still exercise caution in crowded areas, such as the airport. Airports, by nature, are busy hubs with a constant flow of people coming and going. As such, they can be attractive locations for various types of crimes, from petty theft to more serious offences.
When transiting through HKG, it is essential to be vigilant and aware of your surroundings. Keep your belongings secure and within sight at all times. It is also advisable to follow any security measures and guidelines implemented by the airport, such as using the provided trays for electronic devices and metal items during security checks.

These items must be placed in tamper-evident sealed plastic bags and subjected to enhanced security screening using specialised equipment. Passengers with connecting flights to the U.S. should also be aware of additional security measures required by the U.S. Department of Homeland Security regarding electronic devices.
When it comes to leaving the airport during a layover, there may be some restrictions depending on your specific situation. In most cases, if you are a transit passenger and your baggage is checked through to your final destination, you will not need to clear immigration or customs and can remain airside. However, if you choose to go through immigration and exit the airport, you may encounter challenges upon re-entering, as technically you would be entering the country from Hong Kong, which may cause issues with customs at your final destination. Therefore, it is crucial to make an informed decision based on your specific circumstances and the requirements of your layover.
