This depends on entry route, not nationality:
Enter Tibet from Nepal:
- Usually requires China Group Visa + Tibet Permit
- BUT:
- If your nationality has China visa-free access,
you may skip the group visa and use only the permit
- If your nationality has China visa-free access,
Enter Tibet from mainland China:
- No group visa needed
- Either:
- normal China visa OR
- visa-free entry
- Tibet Permit
