Despite a backlog at registration centers Germany has sent hundreds of asylum seekers back to Greece, the move coming as German chancellor Angeal Merkel faces formidable opposition in the coming September elections.
A 2011 ruling by Germany's constitutional court prevented the deportations of migrants but the country is now able to circumvent the earlier ruling.
Almost 400 asylum seekers have returned under the Dublin convention, which states that asylum claims should be dealt with in the first EU country they enter.
Greece said it agreed to take some asylum seekers back in a goodwill gesture, as there had been "pressure" from some EU countries to do so however the number continues to rise.
The transfers to Greece only affects migrants who arrived in Germany from mid-march 2017.
