Congratulations!  You will become a U.S. citizen automatically when you enter the U.S. as a lawful permanent resident while under the age of 18 years.  Since your father was not a U.S. citizen when you were born, you did not automatically become a U.S. citizen at birth.  If you had been present in the U.S. as a permanent resident when your father naturalized, you would have become a U.S. citizen on that day.  So, you will need to enter the U.S. with your green card before you can become a U.S. citizen.  After you enter, you can either apply for a U.S. passport or a Certificate of Citizenship to prove your citizenship.  

USCIS allows individuals who have filed a timely request for extension to remain in the US until the time that the extension request is adjudicated. Of course, if the time requested is close to expiration and there has not yet been an adjudication, the agency would expect the individual to leave or to submit another application prior to the ending date of the requested extension.
