Opening a bank account in Hong Kong is very straightforward, much more so than in the US, UK or Europe. To open a bank account in Hong Kong all you require is ID and proof of address in your home country. It is not necessary to be resident in Hong Kong or have a work visa in Hong Kong and a tourist can easily open a bank account in the city.
For those with an address in Hong Kong you need to provide proof of address, such as a utility bill or official government communication. Non residents need to also provide one of these documents from their home country address. The bank will then post a letter to that address which you must furnish at the bank to open the account. Accepted forms of ID are passport or Hong Kong Identity Card.
