Opening a Bank Account in Belize is not as simple as in North America or Europe. As a non-resident or citizen you need to apply to the central bank for permission to open a bank account.
In this application you must:
1. Provide a utility bill to show where you live (and that it is in Belize).
2. Passport (simple)
3. 2 letters of recommendation from your bank(s) in your home country stating general balances, where the money is generated from, and your status with the bank. You can also have a letter from your accountant as a professional person stating similar things.
4. Letter from you stating why you want a bank account.
Once you put your application in, you now get to wait. Supposedly the time to accomplish this is around 1 month. I am still waiting, as it took me a month to get a utility bill. So I don't how long I will be waiting for. I am enrolled in the QRP program. That Belize government program requires that I have a Belize bank account. That does not matter. Even though they thoroughly vet me as a person, and my background for the QRP, it gets done yet again for the bank.
Talking with residents, and citizens having a bank account does not give you access to the money in that account, or money sent to that account. If they believe the amount of money is large (think 3rd world), then you will have to justify to them why you are spending, or receiving this amount of money. When I contracted a company to build a workshop on our property, they delayed them receiving the money until they could prove that they had a legitimate contract for that amount of money to build something. Another couple told me that they had to have the seller of a vehicle come in to support their claim that they were purchasing a car from him.
These are the rules, so just be prepared for them and expect them. Then you will not get frustrated by them. Frustration only bothers you, not the banks.
