Hi John,
Geeting from Peggy, Top China Travel.
Yes, you can get your Tibet Travel Permit in Hong Kong, as well as in other cities in China.
But there are some conditions to get that:
1. Tibet Travel Permit only can be got by Tibet local agancy only, but agencies in Hong Kong and other cities in China can help you to connect Tibet agencies to apply the Tibet paper.
2. The Tibet vis only can be handled between agent and agent, not agent and individual. That means you have to firstly book a Tibet tour with one agent in China, and then let the agent staff to continue the procedure.
3. One more thing should let you know that your passport and visa scan copies are needed to apply Tibet permit. And better to apply the permit at least 20 days before your Tibet tour. The ealier the better.
As Top China Travel is one of the China local agents. we can deal with Tibet Permit for you. So if you need our help, just let me know your Tibet information incuding your Tibet tour plan in any moment.
Best regards
Peggy
