Who are US senators not born in US?

As of my last knowledge update in October 2023, several U.S. senators were not born in the United States. Notable examples include Senator Ted Cruz, who was born in Canada, and Senator Marco Rubio, who was born in Florida but to Cuban immigrant parents. While most senators are U.S.-born citizens, the Constitution allows naturalized citizens to serve in the Senate. However, the number of non-U.S. born senators is quite limited.
