Former official language 
In the Philippines, Spanish was the country's first lingua franca from the beginning of Spanish rule in the late 16th century, through the country's independence, until a constitutional change in 1973. Spanish was then re-designated an official language by presidential decree, and remained official until the 1987 Constitution removed its official status.
On 8 August 2007, President Gloria Macapagal-Arroyo announced that the Philippine government asked help from the Spanish Government in her plan to reintroduce the Spanish as a required subject in the Philippine school system. The Constitution of the Philippines states that "Spanish and Arabic shall be promoted on a voluntary and optional basis" and that the Constitution itself will be translated into Spanish. It is estimated that in 1996 there were 1,816,389 Spanish speakers in the Philippines.
Commonly used language 
Spanish is the most studied foreign language in the United States and many important public documents are published in both English and Spanish. Spanish is also de facto official in the U.S. state of New Mexico along with English and is increasingly used alongside English nationwide in business and politics. With over 50 million native speakers and second language speakers, the United States now has the second largest Spanish-speaking population in the world after Mexico. The Spanish language is not official but also holds a special status (in the education system, the media, and some official documents) in Andorra and Gibraltar. Spanish is used for international commerce in Brazil due to being surrounded mostly by Spanish-speaking countries and Spanish is widely taught as a foreign language. A similar situation exists in Belize, where Spanish is the first language of almost half of the population.
