can i become a U.S. citizen if both my parents are U.S. citizens even though i was born abroad?

If your father was physically present in the US or in Puerto Rico for five years prior to your birth, two of which years were after the age of 14, you should be a US citizen. All persons born in Puerto Rico are US citizens, and your father should be able to transmit his citizenship to you. Your mother’s having attained her citizenship now would not help you as you are now over the age of 18 and otherwise illegal in the U. S.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
