Medicaid (Full-Scope and Emergency)-
Medicaid is a health coverage program for low-income individuals, children, families, elderly, and the disabled. Each state runs a Medicaid program, though many give it a different name.
Two types of opportunities for medical care are offered under Medicaid: Emergency Medicaid and Full-Scope Medicaid. Permanent residents generally qualify for Emergency Medicaid without exception, assuming they meet the general, non-immigration-related eligibility requirements.
To qualify for Full-Scope Medicaid, permanent residents must, in most cases, have been a permanent resident for five years. A handful of states require 40 quarters of work before providing Full-Scope Medicaid benefits.
Medicare (Hospitalization/Free and Buy-In)
There are two types of Medicare: Hospitalization/Free and Buy-in.
Hospitalization/free ("Part A") Medicare provides health benefits to people who have worked in the U.S. and paid Social Security taxes long enough and are:
65 years or older
Disabled, or
Facing permanent kidney failure
Persons who have not worked long enough may qualify for the “buy-in” option.
Hospitalization/Free Medicare is generally available to all U.S. permanent residents, assuming they meet the other general, non-immigration-related eligibility requirements.
Buy-in Medicare is available to permanent residents only if they have held that status for at least five years
