I'm organising a trip to China including a visit to Lhasa in Tibet for a group of four people this April. Most of the trip is now booked, but a possible problem has come to light. One of our group has a two-year Chinese visa which is valid until May in an expired British passport. He also has a new passport. This has already been addressed on this site and elsewhere, and everyone seems to agree that if you have a valid passport and a valid visa in an expired passport, that's fine so long as you take both with you and the visa wasn't defaced when the passport was cancelled. The Chinese embassy have confirmed this on the phone.
But I have a complication. Our Tibetan tour operator is now saying that it is not possible to issue a Tibet Travel Permit unless the Chinese visa is in a current passport. Can anyone shed any light on whether this is accurate, or suggest how I might verify this? It seems surprising to me, but I can't seem to find anything that addresses this on the internet.
