Your daughter's husband does not necessarily need to start over. It will depend upon exactly where in the immigration process he was when your daughter passed away. Regardless, he would need a substitute sponsor in order to get his green card. To be his substitute sponsor you will be required to sign an affidavit of support agreeing to reimburse various federal, state, and local governments if he accepts means-tested benefits. Aliens have also used these affidavits of support to sue sponsors for a certain level of support. I would proceed with caution. You can read more about the affidavit of support at http://myattorneyusa.com/sponsoring-for-immigrant-visas-or-adjustment-of-status.
