Under current citizenship laws, you would not derive citizenship on these facts, because you would have had to have been admitted to the U.S. as a lawful permanent resident before you turned 18. However, you do not say how old you are now, and citizenship laws have changed over the years. The governing law may be different based on the date of your birth. Also, you may have other options in removal court. The important thing right now is that you should consult a qualified immigration attorney on how best to proceed. Your future and ability to remain here in the U.S. are too important for you not to seek the services of a qualified immigration attorney and there are plenty of good ones here in Florida who can help you. Best of luck.
