I am Cherry living in Indonesia I am married Netherlands since 2 years ago. And we had registered our marriage in the gemeente in the Netherlands. I have 4 children, the oldest 27 yo, 25 yo, 22 yo, 17 yo. I have a Schengen multi-entry visa valid until 2018 and I have visited my husband a few times. My husband has got a job as a technician near Belgium and living in Netherlands for now. But he wants to move to Belgium next month and asked me and my children to come to Netherlands and then we would be moving together in to Belgium together. What documents would be needed to prepared from Indonesia for me and my children to get a family reunion visa in Belgium?
I think you need to legalize your marriage and kids birth certificates in the Belgium embassy/consulate in Jakarta. Give them a call and ask. This I think is the most important. Amro
