There are a few things you should know when opening an offshore bank account, even though today, according to their characteristics, they can be considered as "normal" bank accounts.
A lot of "regular" countries, also known as being "offshore havens", as well as their banks, usually accept foreigners.
What you need to remember is to always look professional when you go to the bank, to be prepared to tell details about yourself and your business, as well as the reasons why you want to open a bank account there.
Finally, apart from the traditional offshore bank account opening, where you have to be physically present, there are some other options, such as remote bank account opening and app-based banks.
But be careful, as they can be less reliable and efficient, as well as time-consuming.
