US dollars are widely convertible in the Tibetan land but the exchange rates may not be very attractive than elsewhere. So, we recommend you to change your dollars into the Chinese Renminbi (RMB or CNY) at much higher rates in Kathmandu before you begin your trip. In fact, the Chinese currency is easily acceptable throughout Tibet while the US dollars may not be acceptable at small teahouses or hotels.
