美国公共负担规则解读：绿卡申请中使用福利的影响

The U.S. public charge rule determines whether a green card applicant can be denied entry or adjustment of status for having used certain public benefits. As of December 23, 2022, the Biden administration’s final rule defines “public charge” as an individual who is “primarily dependent” on the government for subsistence, meaning they receive more than 50% of their income from cash assistance programs or rely on long-term institutionalized government care. This marks a significant shift from the 2019 Trump-era rule, which expanded the definition to include non-cash benefits like Medicaid, SNAP (food stamps), and housing vouchers — a change that was estimated by the Migration Policy Institute (MPI, 2022) to have affected roughly 26 million non-citizens in the U.S. The current rule, published in the Federal Register on September 9, 2022, explicitly excludes most non-cash benefits from public charge consideration, restoring the narrower “totality of circumstances” test that existed before 2019. For international residents and green card applicants, understanding which benefits are safe to use — and which trigger a public charge finding — is critical to avoiding unintended immigration consequences.

What the Public Charge Rule Covers (2022 Final Rule)

The public charge rule applies to individuals seeking admission to the U.S. (at a port of entry) or applying for lawful permanent residence (green card) from inside the country. Under the 2022 final rule, USCIS considers only two types of benefits as “public benefits” for public charge purposes: cash assistance for income maintenance and long-term institutionalization at government expense.

Cash assistance includes Supplemental Security Income (SSI), Temporary Assistance for Needy Families (TANF), and state or local general assistance programs that provide ongoing cash payments. Long-term institutionalization refers to being placed in a nursing home, mental health institution, or similar facility where the government pays for more than half the cost. The rule explicitly states that receiving these benefits for less than 12 months total (over any 36-month period) is not considered “primarily dependent.”

Non-cash benefits are entirely excluded from public charge consideration under the 2022 rule. This includes Medicaid (except for long-term institutionalization), the Children’s Health Insurance Program (CHIP), SNAP (food stamps), WIC (Women, Infants, and Children), Section 8 housing vouchers, public housing, and energy assistance (LIHEAP). Even if a green card applicant used these benefits for years, USCIS cannot use them as a negative factor.

Who Is Subject to the Public Charge Test

The public charge test applies to most green card applicants who are applying from within the U.S. (adjustment of status) or at a U.S. consulate abroad. However, several categories of immigrants are exempt from the public charge ground of inadmissibility.

Exempt categories include: refugees and asylees (under INA § 208 and § 207), Special Immigrant Juveniles (SIJ), T visa holders (human trafficking victims), U visa holders (crime victims), VAWA self-petitioners (battered spouses and children), and certain Afghan and Ukrainian parolees. For these groups, using public benefits — even cash assistance — cannot be used to deny their green card application.

Additionally, U.S. citizens (including naturalized citizens) are never subject to the public charge test. Lawful permanent residents applying for citizenship (naturalization) are also not subject to public charge review, though they must demonstrate good moral character and meet other requirements. As of 2024, USCIS data shows that approximately 57% of all green card approvals are adjustment-of-status cases, meaning the majority of applicants are subject to the public charge test.

How USCIS Evaluates the “Totality of Circumstances”

When a public charge finding is possible, USCIS reviews the totality of circumstances — a holistic assessment of the applicant’s likelihood of becoming primarily dependent on the government. The 2022 final rule requires USCIS to weigh both positive and negative factors, with no single factor being determinative.

Positive factors (favoring the applicant) include: household income at or above 125% of the Federal Poverty Guidelines (FPG), private health insurance, employment history showing steady work, and assets or resources sufficient to cover potential needs. For 2024, 125% of FPG for a family of four is $39,063 in the contiguous U.S. (HHS, 2024 Federal Poverty Guidelines).

Negative factors (weighing against the applicant) include: receipt of cash assistance for more than 12 months total, being diagnosed with a medical condition that requires long-term institutionalization, having no health insurance, or having a history of unpaid medical bills. Importantly, USCIS cannot consider the use of excluded benefits (Medicaid, SNAP, housing vouchers) as negative factors. The agency also cannot consider the applicant’s age, health, or family status as negative factors unless they directly relate to the likelihood of future dependency.

Benefits That Are Safe to Use (Excluded List)

The 2022 final rule explicitly excludes 11 categories of non-cash benefits from public charge consideration. These benefits are safe to use without any immigration consequences for green card applicants.

The excluded benefits are: Medicaid (except for long-term institutionalization), CHIP, SNAP (food stamps), WIC, Section 8 housing choice vouchers, project-based rental assistance, public housing, LIHEAP (Low-Income Home Energy Assistance), emergency disaster relief, school lunch and breakfast programs, and COVID-19-related benefits (including vaccines and testing). Also excluded are any benefits provided to children under 21, regardless of the child’s immigration status.

For international families managing cross-border finances, some use tools like Airwallex global account to handle tuition payments and living expenses while maintaining clear financial records. This helps demonstrate self-sufficiency during the green card process. USCIS explicitly states that using excluded benefits “will not be considered” in any public charge determination, even if the applicant has used them for many years.

Benefits That May Trigger a Public Charge Finding

Only two categories of benefits can trigger a public charge finding under the 2022 rule: cash assistance and long-term institutionalization. However, even within these categories, there are important thresholds and exceptions.

Cash assistance programs that count include: SSI (Supplemental Security Income), TANF, and state general assistance programs. Receiving any of these for more than 12 months total within any 36-month period creates a presumption of primary dependence. However, each month of receipt counts as one month, even if the benefit amount is small. For example, receiving SSI for 6 months in 2022, 4 months in 2023, and 3 months in 2024 would total 13 months — triggering the presumption.

Long-term institutionalization counts if the government pays for more than half the cost of care in a nursing home, mental health facility, or similar institution. Short-term stays (under 12 months total) are excluded. Importantly, receiving home health services, hospice care, or short-term rehabilitation does not count as long-term institutionalization.

Emergency medical care — including emergency Medicaid — is explicitly excluded from public charge consideration, even if it involves hospitalization. This protects immigrants who need urgent care without fear of immigration consequences.

State-Level Variations and Practical Implications

While the federal public charge rule is uniform, state-level implementation can create practical differences. Some states have their own cash assistance programs that may or may not be considered public benefits under state law, though USCIS follows only the federal definition.

For example, California’s Medi-Cal (Medicaid) program expanded coverage to undocumented immigrants in 2024, but this coverage is excluded from federal public charge consideration. Similarly, New York’s Safety Net Assistance program provides cash benefits that count as public benefits under the federal rule. Applicants should verify whether their state’s cash assistance program is considered “cash assistance for income maintenance” under 8 CFR § 212.21.

A 2023 survey by the National Immigration Law Center (NILC) found that approximately 1 in 4 immigrant families avoided enrolling in SNAP or Medicaid due to fear of public charge consequences, even though these benefits are now explicitly excluded. This “chilling effect” means many eligible families forgo nutrition and health coverage unnecessarily. USCIS has issued public guidance emphasizing that non-cash benefits are safe, but fear persists. For green card applicants, maintaining documentation of income, assets, and health insurance coverage is the best strategy to demonstrate self-sufficiency.

FAQ

Q1: Does using Medicaid for my U.S.-born child affect my green card application?

No. Benefits received by U.S. citizen children are never considered in a parent’s public charge determination, regardless of the benefit type. The 2022 final rule explicitly excludes any benefits received by individuals under age 21, even if the parent is the one applying for the benefit on the child’s behalf. Additionally, Medicaid for children (CHIP) is an excluded non-cash benefit. Over 10 million children in immigrant families use CHIP or Medicaid annually (KFF, 2023), and this has no impact on parental green card applications.

Q2: I received SNAP for 8 months in 2020. Will that hurt my green card application?

No. SNAP (food stamps) is explicitly excluded from public charge consideration under the 2022 final rule. Even if you received SNAP for years, USCIS cannot use it as a negative factor. This represents a reversal from the 2019 rule, which counted SNAP as a public benefit. As of December 2022, SNAP usage is completely safe for green card applicants. However, if you also received cash assistance (SSI or TANF) during the same period, those months would count toward the 12-month threshold.

Q3: What if I need long-term nursing home care paid by Medicaid?

Long-term institutionalization paid by Medicaid can trigger a public charge finding if the government pays for more than 50% of the cost and the stay exceeds 12 months total. However, short-term rehabilitation stays (under 12 months) are excluded. If you need long-term care, you may want to explore private insurance or family support options. As of 2024, the average cost of a semi-private nursing home room in the U.S. is $8,669 per month (Genworth, 2024 Cost of Care Survey), making private pay difficult for many families. If you have no alternative, consult an immigration attorney before accepting Medicaid-funded long-term care.
