I know one hostel where foreign backpackers can stay and work for their room. Some people do it for a few days, some people do it for weeks or even longer a few months. Shorter visitors just help clean up and longer-term get more into helping manage the desk.
These are not people here and have a job or are students in Taiwan. They’re just backpacker’s roaming around Taiwan or Asia.
Is it legal? Are there now places like this?
