It's sort of a non-question.
What types of immigrants are we talking about?
Technically people here under visa applications are non-immigrant workers. They have a sponsor. And having written such applications, part of the process is showing the liquidity to pay for and support such a worker. That includes health insurance, housing, and so on.
So a situation in which they would have no support would indicate some rupture in the original terms stated and would spell fraud or a breach of contract.
But those aren't immigrants. They are non-immigrant workers.
The only immigrant category of non-citizen status is the green card. The intention is permanent resident status. I know people whose spouses are in this category. Citizenship isn't granted upon marriage. Also people having received asylum have this status. It seems the same access to social services as citizens for green card recipients. They are paying taxes, medicare, medicaid. And so on.
I don't really get who such a law would impact. Must be people with illegal status seeking asylum, green card, or a legitimate non-immigrant worker visa status. It seems if we had legitimate immigration reform, this category of people wouldn't exist.
