This is a quite odd anomaly and I am not sure why but here you go………
As of October 30, 2010 the United States Department of State does not accept Puerto Rican birth certificates issued prior to July 1, 2010 as primary proof of citizenship for a U.S. passport.
The Puerto Rican government passed a law that went into effect on October 30, 2010, invalidating all Puerto Rican birth certificates issued prior to July 1, 2010. The law does not affect Puerto Rican born citizens who already have a U.S. passport. As of October 30, 2010 the Department of State only accepts Puerto Rican birth certificates issued on or after July 1, 2010 as primary evidence of U.S. citizenship.
To order a new birth certificate and for information on the Puerto Rican birth certificate law, please visit the Puerto Rico Federal Affairs Administration website at:
