It’s impossible to know what exactly you will need to bring to any given country based on the fact that you don’t know exactly where you’ll be living. Most countries have several different climates and the area where you do the pre-service training may have a completely different climate than where you’ll be living. With that in mind, pack more for training and supplement later. And for  the love of all things holy, take out those extra pair of shoes and bring more comfort foods.
