Thanks everybody, I appreciate guys.

I got some quotations from few travelling  agents and I am about to buy one. They gave me tickets through Dallas- Frankfurt-Baharain-Kathmandu. But one agency told me that you can not have layover in Baharain for more than 8 hours. My layover is 16 hours. Does anyone know anything about it ? Has anyone travelled via Baharain recently ?

PS. Also my visa to usa has expired and I cannot travel via countrieslike UK, HOngkong and some other.
