Claude Muhayimana and Innocent Musabyimana will appear before the judge in the Paris Wednesday to find out whether or not they will be extradited to Rwanda, Radio France Internationale reported.
The two men are suspected of taking part in separate massacres of Tutsis in north and northwest Rwanda during the country's 1994 genocide.
Previously, the men were saved from extradition when a French court ruled that no crimes were committed at the time of the alleged offenses.
Defense lawyers have argued the court's change in position was politically motivated and is aimed at easing tensions between Rwanda and France.
France has never before extradited a genocide suspect to Rwanda.
