He has no choice but to live with non-Muslims
Question

                I live with ten colleagues from different countries. Nine of them are Christians, and one is atheist. We eat the main meal together at one table. Every day a different pair from us prepare the meal. Is it Islamically permissible for me to eat with them? Bear to mind that I cannot live alone due to my financial and educational circumstances.
Praise be to Allah.Islam is based on ease and relieving hardship. You can carry on living with them so long as you cannot live alone, but you should call them to Allaah by your words, deeds and interactions with them, in the hope that Allaah might guide them through you. 
And Allaah is the Source of strength. May Allaah send blessings and peace upon our Prophet Muhammad and his family and companions. End quote.
