All tourists visiting Tibet require valid Chinese visa & a special Alien Travel Permit which they can obtain only by recognized travel agencies. Those who arrive in Kathmandu with a Chinese visa issued by Chinese consulates outside of Kathmandu will be of no use. Hence clients entering Tibet via Nepal should not obtain any Chinese visa. There is no minimum group size requirement for traveling to Tibet. As long as one is traveling in an organized tour visa will be issued for even individuals.
Tibet visa regulation often change and hence given information may not be true at the time when you travel. Diplomatic passport holders must get clearance from Beijing for travel into Tibet which often takes long time. It is advisable to travel on non-diplomatic passports, if you have one. We need copy of passport at least 25 days in advance to process Tibet permit in Lhasa without which Chinese Embassy in Kathmandu will not issue visa. Once clients arrive into Kathmandu we will collect passport and take to Chinese Embassy for visa.
