My uncle filed his application in 2015 ...
As of May 2019 still nothing .... he waits for his ASPA, and lives with 219 euros per month!
They take more than 6 months to process a document .... and each c rebelotte .... we need if we have not received it! It is really unworkable to leave elderly people in such precarious situations ...
A question??
Can we go directly to the office of CARSAT in Marseille ... is there a physical home?
