I’ve often thought applying for a Cuban visa or a tourist card was a tricky affair but it’s actually not.
We were in the U.S. so we couldn’t apply for a visa because there weren’t any embassies in the country. I’m Filipino so I can visit Cuba legally. My two American friends cannot because of the embargo. But we did it anyway since we saw a lot of blog posts of Americans visiting Cuba. Just as long as we depart and leave from another country, there was no problem with us returning into the US.
