The Spanish Language gained popularity after the U.S. acquisition of Puerto Rico and also due to the influx of immigrants from El Salvador , Mexico and Cuba .
After the incorporation of these states to the U.S. in first half of 19th century , the Spanish language was later reinforced by the acquisition of Puerto Rico in 1898 and later waves of emigration from Mexico , Cuba , El Salvador and elsewhere in Hispanic America , to the United States beginning in the second half of 19th century to the present-day.
