Normally our Tibet travel agency can obtain the Tibet TTB travel permit 10-30 days before the starting date of the trip. If you book the trip earlier, we can get the permit earlier. However one month in advance is the earliest we can. If you are going to fly into Tibet from any airport in China, you will need the original permit to board the flights. We will send the original permit to you by EMS or Air-Express which takes 1-3 days within China and we need your exact post address such as your hotel or residence address in China (including contact person, contact phone number and the correct name under which the hotel booking is made). If you take the train to Lhasa from Chongqing, Xi’an, Lanzhou, you also need the original permit to get the ticket and we will send it to you by EMS or Air-Express as well. We suggest you take the train ticket in advance to avoid any urgency or unexpected situation. If you take the train from any other city’s station to Lhasa, you only need to have the photocopy of the permit and we will email you the electronic copy to you in advance. The police in Golmud station will check the permit so you should keep it safe. However, our local tour guide will collect your TTB permit after your arrival and guide will need to hold it for your whole trip in Tibet and return all Tibet travel permits to our agency after the trip.
