Hi i am Abdul Azeez. Staying in Oman. My 2 year agreement will get end on August 24'2018. When i joined my present company i joined by giving NOC of my previous employee. Now i have opportunity in another company. So will my present company will give NOC if i ask. Some of my friend said it's mandatory that my present company should provide NOC since i joined with NOC. Can anyone suggest me on this.
