The people of Puerto Rico are citizens of the United States.
"We, the people of Puerto Rico, in order to organize ourselves politically on a fully democratic basis, to promote the general welfare, and to secure for ourselves and our posterity the complete enjoyment of human rights, placing our trust in Almighty God, do ordain and establish this Constitution for the commonwealth which, in the exercise of our natural rights, we now create within our union with the United States of America.
In so doing, we declare:
The democratic system is fundamental to the life of the Puerto Rican community
We understand that the democratic system of government is one in which the will of the people is the source of public power, the political order is subordinate to the rights of man, and the free participation of the citizen in collective decisions is assured
We consider as determining factors in our life our citizenship of the United States of America and our aspiration continually to enrich our democratic heritage in the individual and collective enjoyment of its rights and privileges; our loyalty to the principles of the Federal Constitution; the co-existence in Puerto Rico of the two great cultures of the American Hemisphere; our fervor for education; our faith in justice; our devotion to the courageous, industrious, and peaceful way of life; our fidelity to individual human values above and beyond social position, racial differences, and economic interests; and our hope for a better world based on these principles" - Preamble, Puerto Rico Constitution, July 25, 1952
No, they choose not to become a STATE, they are, however citizens of the US. Alot of them go into the military, where they serve with honor.
err, wrong, fellow-freeper. Citizens they are, even as they remain a commonwealth and not a state. Time to hit the books again...
