Info required please

Hello,

I will be moving to Pointe Noire soon from Muscat- Oman and need some information. We have two young children and our nanny who lives with us to help. Is it possible to bring her to Pointe Noire? She is also Indian, are there any visas for this? She is more like a family member to us, someone we trust a lot and she has worked with my parents before and helped bring me up too! So we are keen on bringing her along if we can and she wants to go with us! Do let me know if you have any info, thanks
