Earlier this month western Europe's last major violent separatist movement said it would put its arsenal of weapons "out of operational use," more than two years after announcing a definitive end to armed activity.
"To continue the process of resolution, it is necessary to bring all prisoners and exiles back home," said a statement from ETA read out in the French Basque village of Arcangues.
"We will begin to walk the streets of our hometowns. You will see us back in the streets and squares of our villages of origin."
ETA said last year that it counted 500 to 600 exiles around the world, including about 150 in France.
The group has also called for the release of some 500 of its members who are held in French and Spanish prisons, which has been a key sticking point in negotiations with Madrid.
