Based on the fact you state, you should be able to file for adjustment of status. You should retain an experienced immigration attorney to review what you filed and to assist you in the next steps of the case.
The statement above is general in nature, as not all the facts are known. You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship.
What type of visa did you use to enter the U.S.?
Overstaying most types of temporary visas would not render you inelgible to adjust your status in the U.S. However, if you entered the U.S. on a K-1 fiancee visa sponsor by another partner or if you entered as C-1/D crewmember or a J-1 exchange visitor subject to the two-year home residency requirement, then you are ineligible to adjust your status.
Did you file an I-485?
