Congratulations for that one extra step! No offense to Ricardo Montalban, I picked his Trek character only because of the actors heritage. “Ricardo Gonzalo Pedro Montalbán y Merino, KSG was a Mexican radio, television, theatre, and film actor. He had a career spanning seven decades,”
And before I’m flamed, I respect Ricardo and his acting, have no idea what his politics were. Okay just checked he was a Republican. Sorry for misusing your memory Ricardo!
Ricardo Montalban never was a US citizen.
From his Wiki page:
Although he spent most of his life in the United States, he remained a citizen of Mexico and never applied for American citizenship
