You can no longer regularize status through marriage or other way after a 180 day overstay without serving a ban up to 10 years That means returning to home country to wait out the ban.
There is some flexibility for the consular office to issue a return visa before expiration of the ban but no guarantee. That’s reserved for humanitarian reasons such as children in USA.[/quote]
This if you elect Consular Processing (CP), as opposed to Adjustment of Status (AOS). If you have a proof that you have entered the country legally (usually I-94 form) you can adjust your status without leaving the country, assuming you are otherwise eligible.
If you have entered illegally you do not have the AOS option and you must go through consular processing. This is where I-601(a) waiver might help.
