International mobility is becoming increasingly important for a successful research career. But, while international scientific experience offers many career-related benefits, it can be difficult to make it happen. And there are some disadvantages.
Over the years, Science Careers has investigated the pros and cons of training in a foreign lab. We've talked to mobile researchers about the many challenges of moving, working, and living abroad. Our interviewees have offered tips on dealing with the logistics of the move, finding a foreign lab, getting funding, applying for a visa -- even finding a school for the kids. We have asked scientist globetrotters about their experiences in a new culture, in and outside the lab. We have solicited advice on how to maximize the benefits of your research experience and ensure it's an enjoyable one. We have wondered whether it is always possible for expatriated scientists to find their way back home and have looked at ways to improve the odds.
Below is a list of what we consider our most valuable articles exploring international research experiences and what makes them successful.
