If you'd like to sponsor another person for U.S. citizenship, you must fill out the U.S. Citizenship and Immigration Services Form I-134. This affidavit attests that the sponsor ensures that the person seeking citizenship will not become a public charge and will be looked after and supported during the citizenship process, which takes five years to complete. By sponsoring another person for citizenship, you are exposed to liability in the event that the immigrant becomes a public charge after becoming a U.S. citizen.
Understand the role of a citizenship sponsor. The federal government is concerned with new citizens becoming a public charge --- that is, being unable to support themselves and becoming dependent on government assistance. The U.S. Department of State, Department of Homeland Security or an immigration judge can deny citizenship or a work visa to any immigrant it deems likely to become a public charge. Serving as a sponsor can help an immigrant gain access to the United States who would otherwise be denied.
Understand the liability associated with citizenship sponsorship. By undertaking a sponsorship role, you are exposed to liability. The sponsor may be required to reimburse the government for any money it expends on behalf of the new citizen. In other words, the U.S. government can commence a lawsuit against the sponsor of a citizen who ends up on public assistance or welfare.
Fill out Form I-134. This form is an affidavit stating that you are financially stable and wish to sponsor the immigrant. Applicants must provide their personal citizenship information as well as a full identification of the immigrant they are sponsoring. Sponsors must also include information about their spouses and children, as well as full disclosure of financial assets. Any persons dependent on the sponsor must be listed. The form must then be signed by the applicant, affirming under penalty of perjury that all information is truthful.
Attend an interview if requested by the U.S. Citizenship and Immigration Service office. Once the affidavit of support has been received and reviewed, the USCIS reserves the right to conduct an interview or to request more evidence.
