In 602.101 Claim for refund AVS form it requires following document:
Legalised, current residence certificate for your family and yourself as well as for the planned place of residence abroad for each member of your family.
So does it mean that I have to find a lawyer in Geneva to legalise my Swiss permit card as well as my ID card from home country, or they also accept a copy?
Considering there are 3 persons in my family, and each legalise document will cost about 150 chf, that's really a big money...150 * 6 = 900 chf..
