what are the visa procedure?

I have a friend who was cancelled but now back in Doha. She was hired and given a visa by a company. She had her medical last August and Fingerprint last September already 3 months pass but until now she have not receive her RP (resident permit). She already given her NOC to her mandoop. Her mandoop told her that her case is not easy because she is now using another name and another designation/position. She was still single in her old RP and her positon is general cleaner employee. Now she is using her married name and her position is receptionist. Does this really matter even she already submitted her NOC and copy of her old RP.

Will it really take that long for her RP to be process because of her case? or it's just that her mandoop is not giving full attention in the processing of her RP?
