I am a non-US citizen on a J1 visa doing an internship in the US. I would like to know if it's still possible for me to travel to Cuba, via Charter Flights in Miami, for example.
Am I subject to the same restrictions as US citizens? Could my re-entry be denied upon arrival from Havana?
No, you're not subject to it - it's the US who has put an embargo on trips to Cuba for their citizens. However, you may have difficulty finding a flight there from the US, as commercial flights generally don't fly there.
I have heard of charter flights doing it, but the most common route is ex-Canada or Mexico - fly there first, then connect to a flight to Havana.
The issue here is many flight search engines (eg Kayak) won't show you flights there, but thankfully there are still other sites that can display available flights.
