Which order do you feel called to? Each has a distinct charism or spirit, and it is important to discern where you belong. Additionally, there are different “varieties” of some of the bigger orders, such as the Franciscans. There are a lot of resources online, which should help you discern. Location should not be the most important consideration.
Becoming a member of an order, secular or otherwise, is a serious commitment. Both you and the order are involved in the process, which generally takes several years. Blessings to you, but do some research and, if possible, talk with your pastor or another spiritual director as you proceed.
