You seem to be ineligible for adjustment of status under the facts you provided. You will need consular processing.
The above is intended only as general information, and does not constitute legal advice. You must speak with an attorney to discuss your individual case.
Because you entered the United States without inspection, even if you get married to a US citizen you cannot adjust your status to a lawful permanent resident in the United States [unless you are eligible under section 245(i)]. After the I-130 is approved, you will need a waiver of unlawful presence before you could be given an immigrant visa at the US Consulate or US Embassy. Waiver applications are highly complex. Don't file Form I-601 on your own. I highly recommend hiring an immigration lawyer to assist you with this process.
