Studying or doing research abroad may be a necessary part of a PhD education. There are many opportunities, whether you are a candidate at the University of Oslo or you are considering coming here as a guest researcher.
Your supervisors and other scientific staff are generally your best advisers if you are planning a stay abroad. They have invaluable contacts and will be able to guide you towards opportunities that will be beneficial to your doctoral work.
The University of Oslo cooperates with a large number of universities and research institutions around the world. Exchange agreements or similar arrangements usually ensures that a stay is easier to arrange and possibly even includes a fee waiver at institutions that would othervise charge a visiting fee.
If you are a PhD candidate at the University of Oslo, you should contact your programme administration while planning the stay abroad. If you are invited to the University of Oslo as a guest researcher, the administration at the faculty or department you are planning to visit may be able to help you with the practical necessities.
