AS FAR AS I KNOW, EXPATS WITH RP IN ANY GCC WITH THE VISA STATUS AS MANAGERS, ENGINEERS AND DOCTORS CAN GET VISA ON ARRIVAL IN OTHER GCC COUNTRIES.

EARLIER WHEN I WAS WORKING IN DUBAI, MY VISA STATUS WAS ASSISTANT MANAGER. I WAS TRAVELLING TO QATAR BY QATAR AIRWAYS.
ON MY FIRST TRIP THEY ALLOWED ME TO CHECK IN AT DUBAI AIRPORT AND WHEN I WAS WAITING FOR BOARDING, ONE OFFICER CAME AND TOOK MY PASSPORT AND HE RETURNED IT AFTER SOME TIME. HE SAID THEY SHOULDN'T HAVE CHECKED ME IN, AND THE STAFF AT CHECK IN MADE A MISTAKE. SO THEY CALLED QATAR OFFICAILS TOOK SPECIAAL PERMISSION TO GIVE ME VISA ON ARRIVAL AT QATAR.
ON MY 2ND TRIP FROM DUBAI TO DOHA, THEY JUST TURNED ME BACK FROM THE AIRPORT AND I HAD TO PONSTPONE MY TRIP UNITL I ARRANGED A VISIT VISA.
SO, BETTER APPROACH UAE EMBASSY AND ENSURE THAT YOU WILL NOT HAVE ANY PROBLEM
GOOD LUCK
