Long-Term Fellowships provide early scientists with up to 3 years of postdoctoral research training in an outstanding laboratory in another country. The third year of the Long-Term Fellowship can be used either for repatriation to the fellow's country or in the host laboratory. To be eligible, a fellow must either come from or go to a member country. Long-Term Fellows who return to their home country at the end of the fellowship may apply for the competitive Career Development Award.
