basically I just have a simple question: is it frowned upon at immigration (or even impossible?) when I re-enter on visa-free entry after making a short stint (like an afternoon) to Hongkong, after having already been in Taiwan on visa-free entry for the past 90 days?
My situation is like this: I came to Taiwan at the beginning of February from the EU on visa-free entry (90 days). At that time I had already bought flight tickets for early May (before the end of the 90 day deadline) to Hongkong where I planned to stay three days and then return to Taiwan, again on visa-free entry.
I am trying to settle down in Taiwan with my girlfriend, but my attempts at finding a job have failed this time and I am not completely through with my university degree application, as the results will be published mid-May. However, since I am living off my savings and do not want to work illegally, I am running a little low on money and was thinking about saving some money by changing my HK itinerary and instead of spending a few days there just return on the same day (which would mean not to leave the airport at all there). (However, I have not checked how much money it would cost me to change the date of the flight tickets yet).
In February immigration only asked me how long I planned to stay in Taiwan, but they didn't want to see my flight tickets (or any other document for that matter). However, I am going to buy another ticket for early August just in case they need proof, I will leave again after 90 days, at least short term.
Although my intentions are good (I chose the somewhat more toilsome way of taking care of finding a job/applying for university in Taiwan directly), I am still a little bit afraid that immigration will find it weird that I am obviously making use of the "90 day" deadline in such a way.
Therefore, I would be extremely grateful if someone who has already done this would share their experiences with me. Thank you in advance.
