I am planning on going to Taiwan for close to 90 days, a period I am eligible for visa-free entry for. Would it be OK (or possible), for me to temporarily fly out of Taiwan just to get another 90 days, as necessary, e.g. do a visa run?
If it makes any difference, the reason for my visit is to visit my Taiwanese wife, who will be there to give birth to our son. We otherwise live and work full time in Japan.
