In most cases, you will be able to keep your bank account when moving abroad. However, it depends on your bank’s policies and your new country’s regulations. A lot of banks will charge higher fees for international transactions, so you’d be far better off financially if you opened a local account.
Alternatively, online and international banks, which cater to expats, can provide flexible options with lower fees and easy access to multiple currencies. Just make sure you check with your current bank so you can understand what options would be best suited.
