Who is Mr. Rashid from Ask Me No Questions and what is their importance?

Mr. Rashid is the second lawyer that the Hossains hire to help with their immigration status. Aisha and Nadira turn to him after Abba's detention, but he informs them that they will have to wait and see. He also accompanies the family to their final appeal for residency, during which, they are permitted to submit their application again and promised it will be accepted this time.
