That is not correct.
Marco Rubio’s parents were naturalized in 1975 as per his website. He was born May 28, 1971. So he was born to parents who were foreign nationals at the time of his birth.

Marco’s father, Mario Rubio, was approved for an immigration visa in Havana, Cuba at the U.S. Embassy on May 18, 1956. He arrived in Miami, Florida on May 27, 1956. He became a naturalized citizen of the United States on November 5, 1975.
Marco’s mother, Oria Rubio, was approved for an immigration visa in Havana, Cuba at the U.S. Embassy on May 18, 1956. She arrived in Miami, Florida on May 27, 1956 with Marco’s dad, Mario. She became a naturalized citizen of the United States on November 5, 1975.
Thanks, JayGalt. My bad...Memory mix up.
The current law says that born to approved immigrants is also a citizen at birth...as does the anchor baby law.
