Q. What publicly funded benefits may not be considered for public charge purposes?

A. Non-cash benefits (other than institutionalization for long-term care) are generally not taken into account for purposes of a public charge determination.

Special-purpose cash assistance is also generally not taken into account for purposes of public charge determination.

Non-cash or special-purpose cash benefits are generally supplemental in nature and do not make a person primarily dependent on the government for subsistence. Therefore, past, current, or future receipt of these benefits do not impact a public charge determination. Non-cash or special purpose cash benefits that are not considered for public charge purposes include:

Medicaid and other health insurance and health services (including public assistance for immunizations and for testing and treatment of symptoms of communicable diseases; use of health clinics, short-term rehabilitation services, and emergency medical services) other than support for long-term institutional care
Children's Health Insurance Program (CHIP)
Nutrition programs, including Food Stamps, the Special Supplemental Nutrition Program for Women, Infants and Children (WIC), the National School Lunch and School Breakfast Program, and other supplementary and emergency food assistance programs
Housing benefits
Child care services
Energy assistance, such as the Low Income Home Energy Assistance Program (LIHEAP)
Emergency disaster relief
Foster care and adoption assistance
Educational assistance (such as attending public school), including benefits under the Head Start Act and aid for elementary, secondary, or higher education
Job training programs
In-kind, community-based programs, services, or assistance (such as soup kitchens, crisis counseling and intervention, and short-term shelter)
