As soon as your plans for a research stay at UiO become definite, we recommend that you make finding suitable accommodation a top priority. This holds especially true if family will be accompanying you.
Since the demand for researcher housing at UiO usually by far exceeds existing facilities, private housing options should be investigated from the very beginning and in addition to a possible application for university housing.
Note: To obtain a permanent Norwegian ID number you need a housing contract valid for at least 6 months.
