The "public charge" test, as a part of federal immigration law, is designed to identify people who are "primarily dependent" on certain government benefits. The government can deny admission to the U.S. or refuse an application for a green card to an applicant whom it determines is likely to become a public charge. In August 2019, the Department of Homeland Security published a new final public charge rule expanding the definition of public charge to consider individuals who receive Medicaid, are age 62 or older, are uninsured or have serious health conditions or disabilities, among other "negative" factors. The Supreme Court issued an injunction to block the rule, but the injunction has been lifted, allowing the rule to go into effect while litigation is pending. The public charge immigration final rule began being implemented on February 24th.
