I got my Visa application rejected two times,

I am living here since 2011, I have finished my 4 contracts in UAE as an employee and now I am working in Ras Al Khaimah my new company has applied for my employment visa application than my application has rejected by immigration due to security reasons, But no any points have mentioned for the rejection, I have already taken physical inquiry from Abu Dhabi CID office, There are no issues against me, But when I reapplied so again my application has rejected, what could happen with me, I don't know, Can anyone tell me your experience regarding same issues, and how it will solve,


Thank you
