If you already have contacts or a network abroad and you’ve made an internship connection already, you can participate in a self-organized internship. This is usually suitable for students who are comfortable working and living in the host country language and culture. You should expect to be fairly self-reliant: ie, able to secure your own housing and navigate around your host city.
