Scope and purpose
This affidavit is a legally enforceable support undertaking used in many family-based immigrant cases and certain employment-based cases. It is not merely a letter promising financial help. Exemptions and alternative forms have specific requirements.
Related rules and practical context
Sponsor eligibility, domicile, income, household size and any joint sponsorship require separate review. A sponsor’s obligations do not necessarily end upon divorce. Form I-130 establishes the relationship, while Form I-485 or consular processing addresses the beneficiary’s status.
