Citizenship and Immigration Canada
(If you're Canadian) You will read and re-read this website looking for immigration loopholes that will allow your beloved Cuban to get to Canada without you having to sponsor him/her. It won't work. You'll eventually make the leap to marriage. But in the meantime you will become much more knowledgeable about Canadian immigration and therefore slightly more interesting and/or irritating at dinner parties
The classic site for all your Cuba love related questions. Getting involved with this website will make you paranoid, angry, depressed, scared...and then hit you with some negative emotions too. If your relationship can survive Cuba Amor, it can survive anything!
Of course, your love is pure, you will never need to send money to Cuba. But just in case...
I actually don't know much about this website. They review casa particulars and seem to have lots of other information about Cuba that I haven't read but that you may enjoy.
