Offshore banks have a wide range of business, including account opening, fund settlement, private equity fund services, wealth management and investment services, as well as other businesses approved by the State Administration of Foreign Exchange. The first step to handle an offshore bank is to open a offshore account. Some large domestic banks, traditional overseas banks and their domestic branches can handle offshore account, and many emerging offshore banks, including Asian banks, can also handle offshore account. At present, it seems that more and more customers choose to handle offshore account directly through offshore banks, which has obvious advantages and is more convenient. For example, Bank of Asia is a bank that provides digital services, which can be done online without on-site handling. In addition, Asian banks also have many characteristics, such as high tolerance (global positioning), strong privacy and bilingual service.

Most offshore banks and local banks can do anything they can. Local banks can do what they can't, and the service is generally good. The premise is that there is enough deposit. That is, if it is not convenient to withdraw cash.
