The US, Ukraine, Russia and Georgia have the most liberal laws in the world, allowing commercial surrogacy, including for foreigners. Several Asian countries used to have liberal laws, but the practice has since been restricted. In 2015, Thailand banned commercial surrogacy, and restricted altruistic surrogacy to Thai couples. In 2016, Cambodia also banned commercial surrogacy. Nepal, Mexico, and India have also recently banned foreign commercial surrogacy. Surrogacy is legal and common in Iran; and monetary remuneration is practiced and allowed by religious authorities.
