I remember when, here in this country, you could sponsor an immigrant family by guaranteeing them a job, etc. That way innocent taxpayers weren’t on the hook. Nowadays, innocent taxpayers and citizens are on the hook for everything.
The U.S. immigration service still accepts affidavits of support when a person sponsors an immigrant. At least they did in 2010. It lasts roughly until the immigrant accomplishes ten years of self-support.
Of course, if the government is the sponsor, then you and I are on the hook, whether we choose to be or not.
