Hmm. As a fiancee visa recipient (now Lawful Permanent Resident) who is necessarily familiar with that area of immigration law, your proposal is probably more interesting than you realize. US Citizens who wish to petition USCIS to grant permanent residency to their fiancee or spouse must, as part of the petition process, sign a form that creates a legal contract with the US Government that the US Citizen sponsor must repay any means-tested social benefits the beneficiary receives. This is in addition to the filing fees incurred as part of the process. Given that this bond must be created as part of the process, I could see your proposal as potentially being OK, except that USCIS would have to set up rules to limit this ability if the sponsor fails in their implicit duties to get the beneficiary on their feet. Basically, I see it as potentially being a privilege, not a right.
