On May 9, 1936, Errol filed his Declaration of Intention to become an American Citizen. He did so at the Calexico border.
A Declaration of Intention is the formal act of a foreigner declaring that it is his or her bona fide intention to become a citizen of the United States, and to renounce forever all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty, whereof he may at the time be a citizen or subject.
When Errol came to Hollywood, before the visas expired, studio stars who were foreign citizens would sometimes leave and return to the U.S. via Mexico. This is what Errol did, as evidenced by his Declaration of Intention.
Errol became a naturalized American citizen on August 14, 1942.
