The duration of the fellowship is for one year, with the option of renewal for a second year. 
In specific fields, where the accepted period for postdoctoral research is longer than two years, the fellowship may be extended beyond two years for an additional 6 months, following review of the situation and agreement by the Foundation. 

Fellows must be based in Israel. If research collaborations require a Fellow to be away from Israel for some time, the period away from Israel should be no longer than 25% of the fellowship period.
