It should be noted that ALL official documents from the Declaration of Independance through the legislation, regulations, executive orders, treaties, federal court rulings, and all other official pronouncements of the present are officially composed and archived in ENGLISH.
One such is H.R. 856 ? The United States-Puerto Rico Political Status Act, 1997 which states in part:
SEC. 3. POLICY
(b) OFFICIAL LANGUAGE- It is the policy of the Congress that English shall be the common language of mutual understanding in the United States, and that this policy shall apply in all of the States duly and freely admitted to the Union. The Congress recognizes that at the present time, Spanish and English are the joint official languages of Puerto Rico, and have been for nearly 100 years; that English is the official language of Federal courts in Puerto Rico; that the ability to speak English is a requirement for Federal jury services; yet Spanish rather than English is currently the predominant language used by the majority of the people of Puerto Rico; and that Congress has the authority to expand existing English language requirements in the Commonwealth of Puerto Rico. In the event that the referenda held under this Act result in approval of sovereignty leading to Statehood, it is anticipated that upon accession to Statehood, English would become the official language of the Federal Government in Puerto Rico to the same extent as Federal law then requires throughout the United States. Congress also recognizes the significant advantage that proficiency in Spanish as well as English has bestowed on the people of Puerto Rico, and further that this will serve the best interests of both Puerto Rico and the rest of the United States in our mutual dealings in the Caribbean, Latin America, and throughout the Spanish-speaking world.
