I'm not sure exactly what 'support' you are worrying about having to provide.
The I864 holds the USC responsible if the immigrant avails themselves of means-tested benefits. That 'support' is different than the type of support a family judge may award your husband (if that is your concern).
I've heard (and the Mermaid might know more about this) that there is some family case law wherein the immigrant presented the I864 to the family judge as evidence that the USC had agreed to 'support' them for 10 years, and prevailed. I've also heard this is very rare. Personally, I think it would take a judge asleep at the wheel to interpret the document in that manner, but I don't have a law degree so that makes my opinion pretty much without merit.
Let's address this issue of support. First, the I864 is a binding contract between the "petitioner" (the USC sponsor) and the US government. That contract is irrevocable and obliges the USC sponsor to make certain that the alien does not avail him or herself of means-tested benefits until he or she is eligible. IF the alien does avail him or herself of such benefits, the terms of the I-864 articulate that the government agency that has provided aid to the alien has the right to and can make a claim for reimbursement from the USC sponsor. And if such agency chooses to do so, the sponsor would either remit payment or face a legal claim from the agency for reimbursement. If the USC sponsor were faced with a lawsuit from the agency, the extant contract (the I-864) would afford the agency judgment in their favour and the USC sponsor would have to pay up.
Agencies have that right. Do they all decide to pursue it? No. But it can and does happen.
Now, as far as the other form of support that rebeccajo alludes to is concerned, this is quite different. First, the I-864 is a contract between the USC sponsor and the US government, and is irrevocable. There have been quite a number of separate civil lawsuits of late filed by aliens that are divorced from USC sponsors to seek some sort of financial aid, using the extant I-864 as a tool to demonstrate that the USC pledged to the government that the alien would not become a ward; that the alien would not have to resort to government aid and that the USC sponsor was going to assure the government of this by asserting that the alien would be kept and provided for to the sum of 125% of the poverty guideline figure ( a figure that would obviate qualification for aid).
These lawsuits, while few in number compared to the vast number of divorced aliens in the USA, can be and have been successful. One may google "
Stump v Stump" a recent Pennsylvania case to see that the USC sponsor can find him or herself providing a sum up to 125% of the Poverty guideline figure for each year that the alien's own income falls below that, until such time the the alien satisfies the Affidavit of Support, by either naturalising, meeting the threshhold that the Social Security Administration has established of 40 qualifying calendar quarters of work, leaves the country permanently or dies. The judgment awarded to an alien that seeks remedy by virtue of this sort of civil lawsuit, would be the difference between his or her own income and that specified as 125% poverty line figure.
Here's the BIG rub! In
Stump v. Stump, the court determined that the language of the I-864 does not articulate that the alien has any obligation to mitigate or improve his or her circumstances. In other words, the court ruled that there is no requirement that the alien mitigate the damages that a potential USC sponsor might incur by seeking work! So, in the worst case, a USC sponsor might find him or herself in such a lawsuit and with a judgment to provide 125% of the poverty guideline figure in damages to the alien for each year that the alien does not earn, and without any requirement for the alien to better his or her income, or even work at all!
While this might appear a gloomy prospect for any USC sponsor, it can be and is, in some situations, reality.
