I went through something similar last year. OFAC blocks can happen for various reasons - sometimes it's just a name match with their SDN list, other times it's the originating country. First step is to request details from your bank about why specifically the transfer was flagged. They should provide documentation. In my case, I had to prove the transaction was legitimate and unrelated to any sanctioned entity. I found helpful information on
ofacblockedfundslawyers.com
that explained the unblocking process. The key is gathering all transaction documentation - invoices, contracts, proof of business relationship. Don't ignore it because OFAC compliance issues can escalate quickly. Banks are extremely cautious with these matters.
