My husband and I want to travel to Chengdu, then continue on to Lhasa via flight. From Lhasa we want to fly to Kathmandu. We know we have to get a Chinese visa and Tibet Travel Permit. However, to get a Chinese visa now, you have to show proof of airline tickets arriving and leaving China. We heard that it is best to not mention visiting Tibet in your Chinese visa application. Therefore it seems impossible to book a flight from Lhasa to Kathmandu. Any suggestions?
