To sponsor your family first the visa should be of the status with which you can sponsor family. Secondly minimum salary to sponsor family should be AED 5000/- Then you have to have a tenancy contract on your name. With all the required documents, you can apply for their residence visa.
To sponsor parents, as per the new law, the salary should be 20,000/- Dhs and a contract of 2 bed apartment.
I think brothers and sisters can be sponsored as well but there is an age restriction.
You can easily get visit visas from tour operators for anyone for 14 days till 3 months.
