I have a related URGENT question to ask if you can help me please.

I got my Qatar's resident permit just 2 days ago, and I and my husband are living in Qatar for 2 months now. My husband is the only one working for now, and I am staying at home. My husband got his resident permit 2 weeks ago.

Now, I wish to sponsor my mother to come to Qatar for around 3 months to stay with us. Can she come here on Family Visit Visa? Can she get visa extensions and stay in Qatar for 3 months with us (or does she need to exit and enter again)? What documents are required for my mother to come?

Kind Regards
