The affidavit of support is a financial commitment whereby the sponsor agrees to provide the necessary financial support to the immigrant, ensuring that the immigrant does not become dependent on public resources. In the case of the K-3 visa, this document is normally signed by the person who initiated the immigration petition, that is, the American citizen spouse who filed the petition.

Furthermore, if the petitioner does not meet the required income criteria, it is possible for a co-sponsor to also sign the affidavit of support. This co-sponsor must be eligible, reside in the United States, and prove that their income meets the established requirements, usually based on a percentage above the federal poverty line. This option ensures that the immigrant has adequate financial support, preserving the intention that the individual does not become a burden on the country”s public services.

It is essential to strictly follow United States immigration laws when preparing and submitting this document. Seeking up-to-date information directly from government sources or specialized professionals can prevent inconveniences and avoid participation in marketing offers or campaigns that promise easy solutions and guaranteed results. Staying well informed and cautious is crucial to safely navigating the immigration process.
