Can a US citizen open a bank account in Portugal?

Written by Admin | Last Updated: July 2026

Yes, US citizens can open bank accounts in Puerto Rico, and because Puerto Rico is a US territory, the banking system is highly integrated with the mainland United States. Non-residents are permitted to open accounts, but because of the specific regulatory environment, you may be asked to provide additional documentation that goes beyond what is requested at a standard domestic bank. This often includes providing a tax identification number from your home jurisdiction and, in some cases, a reference letter from your existing domestic bank to verify your banking history and financial integrity. Puerto Rico also hosts a variety of international financial entities (IFEs) that cater to foreign clients, which may have their own unique set of requirements compared to traditional retail banks. Always clarify the specific documentation and minimum balance requirements directly with the institution you are considering.
