Depending on the length of your overstay, if you leave the U.S. you may be able to obtain a EB-4 visa or you may face a period of ineligibility from entry based upon your overstay.
It is exceptionally unlikely that you'll be able to adjust your status -- that is, remain in the U.S., seek EB-4 status, and gain that lawful status -- from inside of the United States. As we have none of the relevant facts pertaining to your situation, if that's what you're hoping to accomplish, you should speak with an immigration lawyer.
