i am in deportation proceedings how do i get to stay here i came here on a crewman visa 11 years ago

You have extremely limited options available to you. Whether you would qualify for relief from removal will depend upon more information about your ties to this country, country of citizenship, reasons for not wishing to return to your country of citizenship, criminal and immigration history, etc. if not eligible for any immigration benefits, you may be able to request prosecutorial discretion and have your removal proceedings closed. You would be best served by scheduling a consultation with an experienced immigration attorney.
