<prompt> Human: My wife we are both citizens of U.S. wants to sponsor one or both of her parents so they can maybe come and retire? in the United States. If she does this is there any risk to me financially? For example, what if one of them needs some expensive medical care a few years down the road? Or something else I am not thinking of - anyone have experience with this?  <response>: As the petitioner and financial sponsor, you will not only need to show that your income and assets are high enough to avoid the immigrant becoming a public charge, but youll have to promise to pay the government back if the immigrant ends up claiming certain types of public assistance benefits.
