Support Affidavits are an integral component of family-based immigration. They prove to both sponsors and the government that they possess sufficient financial means to support an immigrant in their application for residency status. A Sponsored Immigrant Affidavit will remain in place until the immigrant becomes a U.S. Citizen or accrues 40 quarters of work credit. It also provides evidence of income and assets, such as cash, stocks, and property.

Understanding the Affidavit of Support
An Affidavit of Support is a legal document used in U.S. immigration processes to ensure that an immigrant will not become a public charge. This will help you get a green card and work legally in the USA. The sponsor, usually a U.S. citizen or permanent resident, commits to financially supporting the immigrant if needed.
By signing the affidavit, the sponsor guarantees that the immigrant will have sufficient financial resources, typically meeting 125% of the federal poverty guidelines. This support continues until the immigrant becomes a U.S. citizen, works for about ten years (under the Social Security Act), or leaves the country.
When Is the I-864 Affidavit of Support Required?
An I-864 Affidavit of Support is typically required when sponsoring foreign-born relatives to come permanently into the US to prove their financial capability and prevent their sponsored relatives from becoming public charges. Choosing an experienced immigration attorney like Colavecchio and Colavecchio Law Office can assist in completing such documents correctly in citizenship and immigration services.

Why Is Affidavit of Support Important?
Form I-864, an Affidavit of Support, is integral to immigration proceedings. Sponsors must file it with USCIS to demonstrate and accept financial responsibility and prevent their intended immigrant from becoming a public charge – someone dependent upon government aid for survival.
Affidavits of support help prevent public charges by guaranteeing that sponsored people cannot access means-tested federal benefits such as Temporary Assistance for Needy Families (TANF) or Supplemental Security Income (SSI).
This long-term financial commitment concludes only when their sponsored individual becomes a citizen, works 40 qualifying quarters (approximately ten years), permanently leaves the US, or dies. Its terms don’t change with changes to household circumstances– instead, sponsors must file form I-865 Sponsor’s Change of Address with I-865 to change address accordingly.
Here’s why you need an affidavit of support for family-based immigrants.
Demonstrating Financial Responsibility
Typically, when petitioning for someone in your family to immigrate to the US, you act as their sponsor. By agreeing to provide them with financial support and ensuring they do not rely on welfare or other forms of government assistance for survival, you take on an important responsibility and act on their behalf as their sponsor.
The Affidavit of Support (Form I-864) provides sponsors with an effective tool for demonstrating their financial stability and ability to prevent their sponsored relatives from becoming public charges. Furthermore, this document establishes a binding legal contract between the sponsor and sponsored immigrant that may be enforced against civil lawsuits from either them or any federal, state, or local government agency or private entity providing means-tested benefits.

Preventing Immigrants from Becoming Public Charges
The Affidavit of Support prevents immigrants from becoming public charges by holding their sponsors financially responsible. A “public charge” refers to an immigrant who relies on government assistance. When a sponsor signs the affidavit, they legally commit to providing financial support to the immigrant if necessary.
This ensures that the immigrant won’t need to depend on public benefits like food stamps or Medicaid. This contract allows the government to seek reimbursement from the sponsor if the immigrant receives such benefits. The goal is to protect U.S. resources while ensuring the immigrant has adequate financial support from private sources.

Establishing a Minimum Income Requirement
Submitting an Affidavit of Support is legally mandatory for most families. This protects public resources while ensuring sponsors can sustain the intended immigrant’s finances.
Financial sponsors are required to submit an affidavit showing they earn at least 125% of the federal poverty level for their household size. Assets like checking and savings accounts, stocks, or bonds may count towards annual income; however, they must be converted to cash within one year.
U.S and Non-U.S Citizen's Income Requirements
Sponsors typically must be U.S. citizens or LPRs; however, courts have established that a non-U.S. citizen legally married to their sponsor may sign an affidavit of support. This can help overcome problems caused by many sponsors living overseas for work related to government or active duty military contracts and not being available to provide sufficient financial support for sponsored immigrants.

Providing a Legally Binding Commitment
An Affidavit of Support (AoS) is a legally enforceable contract between sponsors and their sponsored immigrants. If sponsors fail to fulfill their financial obligations, the immigrant can pursue them in federal court to enforce their financial commitment.
State laws regarding alimony payments do not affect an affidavit’s financial obligations, making it enforceable against sponsored immigrants and any Federal, state, or local agency providing means-tested public benefits to them.
Sponsorship obligations expire once their sponsored immigrant becomes a U.S. citizen or earns 40 work quarters, typically taking ten years, and when either their sponsor, substitute sponsor, or joint sponsor dies.

Submitting the Form I-864 to USCIS
An Affidavit of Support (AoS) is a legal requirement in most family-based immigration cases and must be completed to be considered valid. To complete this form, you will need proof of sponsor’s income, such as pay stubs and tax documents, as well as documentation about your assets, such as real estate or bank accounts.
Sponsors must also sign an affidavit to make it legally binding. This commitment to provide financial stability ensures that immigrant families won’t become dependent on public assistance programs and upholds both immigration processes and social safety nets.
Impact on Sponsor’s Financial Liability
Though lawsuits against sponsors are uncommon, those considering sponsoring noncitizen relatives should understand the financial commitment they’re entering into before sponsoring one. The INA and Form I-864 state that if a lawsuit occurs against sponsors, they must pay attorney fees to their plaintiff-beneficiaries as stated by law.
Sponsors may also be required to reimburse government agencies for means-tested public benefits received by sponsored immigrants, such as:
- Food stamps
- Medicaid
- Temporary Assistance for Needy Family members.
- Supplemental Security Income during the sponsorship period
Failure to fulfill this legal requirement can be expensive and have serious repercussions for an individual’s credit and finances; long-term sponsorship responsibilities typically last until an individual becomes a U.S. citizen, completes 40 quarters of work, or leaves the country permanently.

Conclusion
The Affidavit of Support is a crucial component of family-based immigration in the U.S. It establishes a legally binding commitment for sponsors to ensure that immigrants do not become a financial burden on the public. Failure to meet these obligations can result in legal action and financial repercussions, making it imperative for sponsors to assess their capacity before committing.
