Airport to Airport Visa Change

The whole idea of A to A is that the passenger will exit the country on a plane and return back to the airport with UAE visa. Now A to A literally means that you travel from either Sharjah International Airport and from either of the airports you take a plane to either Muscat (Oman), Kuwait or Bahrain as per the flight availability which will be booked by your agent. Before you board the flight, the exit stamp from the immigration needs to be sent so your new UAE visa is posted. After sending the exit stamp, aboard the flight to whichever airline your agent has booked for you, for example the flight from Sharjah to Muscat. After reaching Muscat you have to exit the flight, enter the airport terminal, get a stamp from your Muscat to Sharjah boarding pass and board the same flight again. After reaching upon Sharjah, you need to wait at the airport waiting area until your UAE visa is approved.
It seems to be very complicated, but it’s the easiest visa change process out of the rest.
