I have also never been out of my country and I assume neither have you but then also I only got the reason of purpose of visit but you also get travel history. Who says that there guys aren't biased waisting months of students time. And for you're question about the travel history I have no idea what you can write. It will best to ask a you're agent if you have one. And if not you can get one now also, they will help with you're application and also suggest ideas on how you can approach this. But remind you they will charge their fees to help you with you're application
