Hi
With the latest news about Tibet Travel Permit on May 9th, Tibetan Tourism Bureau announced a new policy that all the foreigner who want to visit Tibet, must group at least 5 people with same nationality, otherwise is not allow to submit the Tibet permit.
That means, if you are
► Travel alone
► In couple
► Or even in triple
► Or in a 5 (or above)-pax group with tourists in different countries
You could not get permit approved unless you can find countrymates to join the group and make the group size larger than 5.
The policy had been implemented since May 9th. While the validity of this policy is still unclear since there is no official news about that.
