How to send crypto from USA

So I wanted to send $1000 usd from USA to someone in iran, I bought some usdt from Kraken, sent it to a trust wallet and then from that trust wallet sent it to the person in iran, thought this would do the trick, but Kraken holded my usdt and closes my account, now I’m looking for alternative way to do this. I don’t want any risk of the same thing happening again.
