You can request reconsideration by providing additional information or changed circumstances. There’s no formal appeals process within OFAC, but you can submit supplemental information explaining why the denial should be reconsidered. If OFAC maintains the denial, you could potentially seek judicial review, though courts generally defer to OFAC on licensing decisions. Sometimes denials are based on insufficient information in the application, so addressing those gaps in a new application can work. I researched license denial options at this link ofacblockedfundslawyers.com and found that supplementing the record is often more successful than formal appeals. Make sure your initial application is as complete as possible to avoid denials based on inadequate information.
