I need urgent guidance as I’ve received my interview date for the family visa. When we initially submitted the Petitioner's Affidavit of Support (AOS), it showed insufficient financial resources, so we included a joint sponsor and informed the authorities that the applicant has sufficient funds. This allowed the petition to progress to the interview stage. However, due to ongoing family property settlement issues, the joint sponsor is now refusing to provide their recent tax documents. We already have all necessary documents from the Petitioner and sufficient liquid funds to settle in the U.S. Despite this, I’m concerned that this situation could lead to delays or even a visa denial. How can we address this issue, and what steps should we take to ensure the application proceeds smoothly without the joint sponsor's updated tax documents?
