Step-by-step explanation:
When relocating to a new country and ensuring that new bills will be in the currency of the new country, one can contact their bank or use a currency exchange service. Most banks offer foreign exchange as a service to their customers, where they can assist in the process of exchanging a significant amount of currency and provide information on managing accounts in a new currency.
