To ensure financial security during an international move it is important to sort out banking needs both at home and abroad before relocating permanently or temporarily. Research what type of bank accounts are available in your new country as well as any applicable fees or regulations in order to find one that best suits your needs while living abroad long-term or temporarily. Additionally, consider setting up a backup account in case of emergency while consolidating any existing retirement plans such as 401(k)s accordingly due to rules and regulations varying from country to country.
