Unlike their European counterparts, Chinese immigrants had to face various obstacles which prohibited or restricted their entry in Puerto Rico. When Puerto Rico was a Spanish colony, the Spanish government did not encourage settlers of non-Hispanic origin. Even though the Spanish government changed its stance with the passage of the Royal Decree of Graces (Real Cédula de Gracias) of 1815, the decree was aimed at non-Hispanic Europeans who were willing to swear their allegiance to the Roman Catholic Church and not at Asians. After Spain ceded Puerto Rico to the United States in accordance to the Treaty of Paris of 1898, Chinese immigrants faced another obstacle with the passage of the Chinese Exclusion Act (1882) which forbade the entry and immigration of Chinese nationals to the United States and its territories.
