Law / What to do after being denied a visa to Poland? [7]

Hello everyone,

My Colombian boyfriend was granted a Polish student visa for the year 2014/2015, which is the year he moved to Poland from Colombia, and as far as I understood the visa was extended for the following academic year (2015/2016). This year, however, his application for a renewal was refused and he is waiting to apply for another one as he hopes to find a job first. He believes this would facilitate the process. Now, him being currently an illegal visitor, would any employer hire him and help him get a visa? Is there anything else that can be done to prevent him being deported? :/

I would really, really appreciate any relevant feedback, and I am particularly looking forward to hear from people who have been through similar situations. This is a very delicate situation for both of us and I would like to know if there is anything I can do to help. (p.s. I have both Italian and Polish citizenships).
