I am an Indian passport holder living in USA, I am travelling to India in December through Saudia airlines. I have a layover period of 10 hours and 13.5 hours respectively while going and coming back to USA in Jeddah in Saudi Arabia. I dont have any plans to go out of airport. Do I still need to apply for transit visa for either of my flights?
According to Timatic, the software airlines use to determine the required travel documents, you may transfer in Jeddah without a visa if your transit time is 12 hours or less. They do have a sterile transit area, but looks like you'll need a transit visa for the return leg of your trip.
I don't know how they enforce the visa requirement within a sterile transit area, maybe someone here has personal experience and could answer that part more clearly.
