I have dual Argentina and United States citizenship and am currently residing in the US. I will be traveling to Brazil in February. My plan is to enter Brazil with my Argentinian passport since Argentinians are visa exempt. I will also be driving a rental car with my US driver's license since my Argentinian driver's license has expired.
Could presenting my US driver's license and passport be a problem in renting a car, or if I were to be stopped by the police? I wouldn't have a tourist visa, which is required for Americans, since I will enter the country as an Argentinian citizen. Alternatively, would it be acceptable to show my international driver's license with my Argentinian passport?
Looking forward to clarification.
