Can my wife stay in hostel and continue her higher studies?

Bismillah Hirahmaan Niraheem. Assalamu Alaikum Warahmathullahi Wabarakathuhu. Dear Brother, I have already submitted 2 questions in your web site. Jassakkallahu Khairun. My fiancé is a gold-medallist in her graduation and she is willing to pursue higher studies in US. She is living in India at present and Insha Allah, she will be coming with to US after our marriage. I have a relocating job in US; so I will be moving to different states during my job. So, after our marriage, my wife might be staying in hostel to complete her study. Also, she is willing to work as a lecturer or a researcher. I kindly request you to clarify the following questions: - Halhamdulillah! I have been sending Islamic and general articles to some egroups, my friends and relatives. She is sending her articles to me to publish. 1. Is my wife after our marriage allowed to pursue her higher education in a Uni-Sex (Coeducation) College? 2. Is my wife allowed to stay in hostel and study? 3. Is my wife allowed to work after completing her studies? 4. Am I allowed to publish my fiancé article before marriage? 5. Is there any limit to which a woman should educated? Waiting eagerly for your kind reply. Jassakkallahu Khairun Khateeran. Warm Regards, Wassalam. Your loving brother. K.S.
