Authorizes provision of comprehensive health care coverage to undocumented immigrant aliens.

New Jersey's Bill A1357 would amend state law to allow undocumented immigrants residing in New Jersey - who meet all other Medicaid eligibility criteria (like income and residency) - to receive comprehensive healthcare coverage through the state's Medicaid program. The bill requires the Commissioner of Human Services to implement systems for this coverage only after confirming federal funding approval, prioritizing federal financial participation before using state funds. It explicitly complies with federal law (Section 441(d) of the 1996 welfare act), which permits states to extend benefits to undocumented immigrants under certain conditions. The bill does not create new benefits but extends existing Medicaid access to this group, contingent on federal approval and system readiness.
