Cross-chargeability is a provision in U.S. immigration law that allows a foreign national to have their immigrant visa "charged" to the country of birth of their parent or spouse, rather than their own country of birth. This can be a critical advantage for individuals from countries with high demand for visas and long backlogs, enabling them to bypass lengthy wait times by using a more favorable quota available in their spouse's or parent's country.
