Being absent from one’s wife for more than six months

I'm getting married back home , but unfortunately I will not be able to bring her to this country because I,m student. I know a Hadith where Omar ibn Alkhatab (RAA)- if I,m right - said that husband and wife must not be way from each other for more than six months. Unfortunately , I will only be able to comeback after a year minumum. Am I allowed to do that using the islaamic principal "necessity dictates exception".

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

If your wife accepts your being away for this length of time, then there is nothing wrong with it. May Allaah bless us and you with all strength and goodness.
