Onshore bank flagging offshore transfers – anyone else seeing this?

Hey everyone, I'm fairly new to the offshore banking world, just opened an account with a reputable institution in Panama for some legitimate wealth diversification. Everything's above board, full disclosure to my home country's tax authority. However, my domestic bank (a major US player) is now holding transfers to my offshore account for what they're calling "enhanced due diligence" checks, even for amounts that are well within typical limits. It's causing delays and extra paperwork. Is this just standard procedure nowadays for all outbound international transfers, or is there something specific I might be overlooking regarding how to set up the originating transfer to make it smoother? Curious if others have found ways to streamline this process, perhaps by pre-notifying their onshore bank or using specific transfer methods.
