Rescinding sponsorship of an immigrant can be a complex matter and may have legal and financial consequences. The specific process and options for rescinding sponsorship depend on the immigration category and the stage of the sponsorship process. It may be possible to withdraw sponsorship if an application is still pending with the U.S. government. If an application has already been approved, the sponsor will need to reach out to U.S. Citizenship and Immigration Services (USCIS) directly to submit a formal cancellation request.
