So long story short, I reneged on a teaching contract with a school in Taiwan after I changed my mind, last year. My personal circumstances changed back then. I was (and still am) abroad back then. It was after I signed the contract. However I may consider coming back to Taiwan to teach.
In any case, for the work permit process, they asked me for a new background check (since the one I submitted to that recruiter had expired) as well as clearer scans of my diploma and teaching certificate. At that point, I decided not to go along with the work permit process. So essentially, I cancelled that job in the process that way.
Since I signed the contract but didn’t continue nor proceed with the work permit/visa process, would immigration in Taiwan blacklist me or prevent me from getting another work visa in the future? Or am I free to pursue another teaching job in Taiwan (other then the one I dropped)in the future?
