Please note: I entered Kosovo this way and wanted to continue on to Serbia. However, they won't let you in there later, because Serbia considers Kosovo to be part of its own state, which you've already entered without authorization, meaning you haven't received a Serbian entry stamp. This meant a huge detour over the Montenegrin mountains for me. This problem only arises if you're traveling with a passport, like me. It shouldn't be a problem with an ID card, because you can't "miss" a stamp!
