International vacation planning can be a lot of fun: picking out where to go, what to do, and when to eat. But overseas travel also involves a lot of documentation. You’ll need passports, boarding passes, local currency, and, depending on your destination, you may need a travel visa. Travel visas can seem pretty intimidating, and the rules for getting visas vary a lot by country. With a little bit of knowledge and realistic expectations, visas don’t have to be scary at all.
