似乎有戏: Question: I heard something about a ‘substitute sponsor’. What is this? Answer: This is a certain other family member who basically now would submit the affidavit of support in place of the deceased petitioner. Under the Family Sponsor Immigration Act of 2002, certain relatives (spouse, parent, mother-in-law, father-in-law, sibling, child (if at least 18 years of age), son, daughter, son-in-law, daughter-in-law, sister-in-law, brother -in-law, grandparent, grandchild, or legal guardian) may be substituted to meet the affidavit of support requirements under INA §213A(f)(5), when the petitioning relative has died. http://www.asianjournal.com/immigration/atty-brian-lerner/15804
