As of my last knowledge update in September 2021, specific interest rates on education loans can vary based on a variety of factors including the borrower's creditworthiness, the loan amount, and the terms offered by different banks and financial institutions. To find the bank offering the lowest interest rate for international students studying in the USA, it's advisable to research and compare loan options from various lenders. Common options for international students include banks like Wells Fargo, Discover, and Sallie Mae, but these institutions may change their terms and rates over time. It's crucial for international students to carefully review and compare loan offers to find the best option tailored to their needs.
