How can I obtain Aliens’ Travel Permits (ATP) for my Tibet Travel? This is another common question about Tibet permits. Permits to visit places that are not declared open are known as Aliens’ Travel Permits (ATP). So if you want to travel to places besides Lhasa, Gyantse, Shigatse, you will need Aliens’ Travel Permits (ATP) issued by Local Public Security Bureau (PSB). A single permit (with a group’s all name list) is normally issued to all the people who are traveling together and the permit just name one of them and states how many others are accompanying him. After you arrive, we need your original passport and visa to apply for the permit in Lhasa or Shigatse and it normally takes only 30 minutes to get this. Our Tibetan tour guide will apply and keep the permit for you.
