Is Physically challenged persons eligible to work abroad..

I got a Shun Visa for a job in Coffee shop in Kuwait for a Cashier post.My employer knew that am a Physically challenged(left leg affected with Polio & slight limpness),but can walk freely & seemed to b not bother about my disability;as a Cashier has to work with his hands,not legs.
But here in GCC centres in India like Chennai,Banglore;doctors r saying that Physically disabled peoples are not allowed to work in Gulfs & I was deemed to b declared Unfit in Physical fitness.
Pls help me with ur valuable Guidance's.

Pls do furnish me the details of any agents in India who can help me to get cleared in medical tests here in India.
