Hi everybody!

My girlfriend will go to Taiwan for a 2 years postdoc experience. We are organizing this short expatriation. Visa partnership possibilities.
I could travel with a working holiday visa (Taiwan-France) but it is impossible to ask for an extension visa after. We have priorities questions:
1. Does it exist Visa partnership to follow a work visa? Do we need to get married? We are not married but live together for 3 years (bank account, etc.).
2. Do are there other solutions or scenarios to go to Taiwan?

Also, if you had the same problematic, all information is welcoming.

Thanks
Have a good day

Quentin
