Tibet Travel Permit
There are two kinds of permits (Tibet visa) for traveling in Tibet: the entry permit (TTB permit) and the Alien's travel permit (PSB permit).
TTB Permit - Tibet Entry Permit (Tibet visa)
When you fly or take train from any city to Lhasa you will need to show this permit when you check in at the airport or railway station. Furthermore, whenever you buy a flight or train to Lhasa you need to show this permit. TTB permits are also needed by groups traveling by Land Cruiser but this will be arranged by the travel agency organizing the trip. Here is a picture of TTB permit:

PSB Permit - Alien's Travel Permit
If you want to go further to the "unopened" areas, you need an Alien's travel permit issued by PSB of Tibet. It is called "Alien's Travel Permit" or "PSB permit". Here is a picture of PSB permit :

- a copy of your Passport;
- a copy of your China visa (tourist visa);

Please note that if you do not book any tour from us, we can not help you get the permits. No travel agency can provide "permit-only" service. Here is a note from Lonely Planet:
"Lhasa PSB will not issue travel permits to individuals and will direct you to a travel agency. Agencies can arrange a travel permit to almost anywhere but only if you book a Land Cruiser, driver and a guide."
