Good day,
At present I am working in Oman and my visa is express visa. I have provided my noc to the present employer which I have received from my previous employer during march 2017,
Due to the unavailability of visa clearance, my present employer brought me to oman 5 times through express visa. Now I want to switch to another company , whether I need noc from my present employer or my noc from previous employer shall be provided to future employer to apply for employment visa
