We had no warning about this. Is there any way to challenge

Hello! Being placed on the OFAC SDN list is extremely serious and requires immediate legal action. The good news is that it’s possible to challenge SDN listings and work toward delisting, though it’s a complex process requiring specialized expertise. I’d strongly recommend contacting https://sanctionslawyers.net/ — they specifically handle OFAC SDN list removal cases and have experience with blocked asset situations. They can help you understand why you were listed, prepare a delisting petition, and engage with OFAC effectively. The firm also assists with release of blocked funds while the delisting process is ongoing. Sebastian Suarez and the team have deep knowledge of OFAC regulations and the administrative procedures for challenging listings. Time is absolutely critical here — the sooner you engage proper legal representation, the better your chances of successful resolution. They can assess whether the listing was based on mistaken identity, incorrect information, or other grounds that could support removal. Contact them urgently for a consultation.
