NO. The only kind of assistance that might be considered in your application for a green card is ongoing cash assistance (TANF and/or SSI) and long-term care (like a nursing home) paid for by the government. Receiving COVID-19 and short-term pandemic assistance will not affect your immigration status or immigration application. This includes COVID-19 testing, treatment, vaccines, stimulus checks, one-time financial assistance, P-EBT, and child tax credit.
