You signed a Form I-864 in order for your stepson to become a lawful permanent resident. Your obligations to support your stepson do not end simply because he moved out of the family home. Your obligations under the affidavit of support will only end upon your stepson (1) becoming a U.S. citizen, (2) no longer being a permanent resident and departing the U.S., (3) obtaining lawful permanent residence through adjustment of status in removal proceedings, (4) earning or being credited with 40 quarters under the Social Security Act, or (5) passing away.
