Getting a Tibet Travel Permit (TTP) is the main hurdle for any foreign traveler wanting to visit Tibet. The rules have changed slightly in recent years, and it's important to get up-to-date information before you go.

Currently, foreigners cannot independently travel to Tibet. You must go with an organized tour through a registered travel agency. This is the rule even if you just want to get the permit to enter.

The process usually takes 7-10 business days, so apply well in advance of your planned travel date. You'll need to send your passport and visa information to the agency ahead of time.
