Interracial and out of religion marriages vary with different classes and are less common amongst traditional people and on the whole are not very popular. It is a lot more prevalent for males to marry non-Muslim foreigners than for females. This is mostly due to the fact that Muslim women are legally barred from marrying non-Muslims unless if the future spouse converts into Islam. Iranian family and inheritance laws favor males. These issues might create serious problems at times of divorce, custody rights and death. - See more at: http://www.iranchamber.com/culture/articles/codes_behavior.php#sthash.hme8yIUs.dpuf
