Israeli nuclear betrayer Mordechai Vanunu received a permit from Norway to move to the country so that he could reunite with his Norwegian wife, who lives in Oslo.
However, it is not yet clear whether Israel will allow Vanunu to move to Norway. After his release from prison in 2004, Vanunu was subject to severe restrictions, including a ban on leaving Israel, on the grounds that he poses a security risk and could reveal other secrets.
Vanunu, 62, married theology professor Kristin Joachimsen in Jerusalem in 2015, a decade after they met.
Joachimsen applied for him to be allowed to come to Norway under rules for family reunification.
Vanunu, a former nuclear technician, was jailed in 1986 for disclosing the inner workings of Israel's Dimona nuclear plant to Britain's Sunday Times newspaper.
He spent more than 10 years of his sentence in solitary confinement.
He has twice been jailed for breaking the restraining orders that were imposed on him after his release.
In January, Vanunu was convicted of meeting with two U.S. nationals in Jerusalem in 2013 without having permission to do so.
Earlier this year, Vanunu received a suspended two-month prison sentence and community work after a Jerusalem court decided against imprisoning him for a misdemeanor from over four years ago.
