Can you explain this? I'm pretty sure Cuban migrants to the US can't remit money to Cuba; that's one of the key points of the sanctions.
I’m sure you can’t just wire the money from a US bank to a Cuban one, but they surely have ways to do it. The island is full of stuff from America they aren’t supposed to have.

Anyway tl;dr is that Cubans use: https://havanaship.net/nueva-agencia-de-remesas-a-cuba-orbit, which is a gov't controlled remittance operator. As of commenting isn't on the OFAC controlled entity list. It used to be sanctioned after the previous remittance operator was associated with the Cuban Army but is now in compliance.
