Since 2008 March 14th in Lhasa, it is regularly forbidden that foreign visitors come to travel in Tibet in every February and March. You should avoid these months and choose other time to travel to Tibet and normally from every April 5 foreigners begin to enter Lhasa (however try to postpone your trip around April 5 and it is generally no any problem). Like in April 2017, our Tibet travel agency arranged around 8 foreign groups entering Lhasa from April 2 to April 15, and the earliest arrival for Kailash tour is April 15, 2017. Normally Kailash travel permits application takes the longest time in Tibet permits process. We will keep it posted instantly under our Tibet travel permits FAQs pages.
