Sorry I missed this. I’ve posted my understanding of the basic legal position regarding the right to autonomous residence here Timeline For Family Reunification through GV - #24 by Lala. On my very quick reading, it looks like even if family members have reached the stage of holding autonomous residence, family renewals can still legally be tied to the same conditions applied to the primary. However this is only true for as long as the primary is subject to those conditions. Once the primary gains citizenship, what the family is left with is autonomous permits subject to general conditions, as we were. What I can confirm for sure is that no proof of the GV investments was required in our case.
