Passport requirements:
All foreigners visiting have a valid passport and VISA to enter the Hong Kong or China and to re-enter their own country. Returning home with an expired passport is illegal and may result in a fine.


Identification:
When traveling, it is important to carry at least two forms of identification including one photo ID. Banks may require various ID's to cash a check, so keep that in mind when visiting one of these services. But remember never to carry all your ID's together; put them in separate places in case of theft or loss.


Student and Teacher Identification:
The "International Student Identification Card" (ISIC), the most accepted form of student ID. If you have one of these it will get you lots of discounts on sights, accommodation, food, and transportation. The reason this card is preferred over others is because it is more recognized and honored abroad rather than a specific card (university card). Cardholders have access to 24-hour emergency help line for medical, legal, and financial emergencies. Holders are also entitled for insurance benefits.


Youth Identification:
For travelers under 25 who are traveling but are not students, The International Student Travel Confederation issues a discount card. This one-year International Youth Travel Card (IYTC) formerly known as the Go 25 Card offers many of the same benefits as the ISIC.


Money:
If you are traveling for more than two days it is recommended that you keep more cash than usual. But if you carry it around with you it's risky even if you have it in a money belt, and many banks do not accept some money checks from other countries even if you have many forms of ID and some other banks won't even accept checks.


Traveler's Checks:
American express and Visa are the most recognized traveler's checks and are one of the safest and least troublesome means of carrying funds. Many banks and agencies sell them for a small commission and they provide refunds if the checks are stolen and additional services like toll free refund hotline abroad and stolen card assistance among others. When traveling keep track of the recipients of the checks cashed. Always bring you passport when cashing a check and if they are lost or stolen immediately contact the refund center of the company that issued the checks. For reimbursement they may require a police report for authentication.


Credit Cards:
Credit Card are generally accepted in the Hong Kong even in some small businesses. The exchange rates that you get when withdrawing cash is sometimes better than going to a bank.


Costs:
The expense of your trip can vary significantly depending on where you go, how you travel and where you stay. For the foreign traveler the highest cost of the trip will be the round trip airfare. If you plan to visit North America renting a car is recommended. A daily budget should be made before traveling.
