Overstay of 10 after visa expiry and cancel visa while exit

Dear Sir,
Please any one answer as we do not get correct answer from any source..
My wife's visa expires on 21-03-2019 and we all family member exiting Oman by cancelling visa on 31-03-2019 . Every one has has valid visa except wife's.
So should i renew it just for sake of 10 days or i can use benefit of grace period?

Hi ashrafg700,

Your wife can avail of the grace period clause.

However, since you are planning to exit Oman for good, all your visas have to be duly cancelled. To do that your company PRO / Sponsor has to be physically present at the airport to do the needed paperwork. Ask him about it now itself. This could be your 'Plan B'.

@ Sumithran,
Dear Sir ,
Thank you for your reply.
Yes. I already spoke to PRO and they will be assisting for cancellation.
So there will not be any penalty for 10 days while exiting right?
