New employment visa in case of a pending labour case

Good day,

I had a labour case for which the judgement has already been issued from the court of the first instance in my favour in Nov 2018.

I have opened an execution file in mid of Feb 2019 & is currently under 15 days notification period. I have now got a new job offer & they want me to join at the earliest.

1) Can I cancel my labour card & residence visa since the judgement is already out so that the new employer can initiate the visa proceedings from the new company?

2) What documents would I need?

3) Will it affect my execution court case in any way since I have not received the EOSB till now & don't want to lose it?

4) During cancellation, do I have to sign that I have received all my EOSB if in case my company PRO cancels it & would it affect the case?

I have approached Tasheel/Amer & different people are giving different opinions & I am confused now. Can you please guide me?

Thanks,

K.K.
