Protect U.S. Investments Act of 2023

This bill strengthens protections for U.S. investors in foreign countries by amending the Foreign Assistance Act. It requires foreign governments to consult with U.S. investors under investment treaties (like those in the DR-CAFTA agreement) within 30 days of a written request. Investors can now petition a U.S. commission for an advisory report on treatment of their investment, and if the commission delays, they may seek court action to suspend U.S. aid to that country. Foreign officials who harm U.S. investments face denied U.S. visas, entry, and blocked financial transactions in the U.S. until the harm is resolved. The bill directly affects U.S. investors, foreign governments, and their officials involved in investment disputes.
