For quite a while I’ve had a Jamaican passport. Having a US Resident Card (green card) is great for living and working in the United Sates but you’re quickly reminded your are still Jamaican when you want to make a spontaneous trip. The Formalities and paperwork involved with obtaining a visa for many countries, coupled with the having to find the appropriate consulates might be a deterrent, but fear not young yardie!
Here are a list of countries you can go to RIGHT NOW without a visa. And if it makes you feel any better, some of them require Visas for US Citizens as well ;)
