There can be a great danger for the women sent back to the country of origin. We have a situation in Denmark where they can still be religiously married but civilly separated or divorced, and in their minds they are still married. For example, when the man wants another wife, he gets a civil divorce and sends wife number one back to Afghanistan. This can mean great danger for her, violence, death, whatever. Rumours may have been started before she arrives that she is a whore, and it can be very dangerous.
The man will often get the children, so the women are victimized greatly by this.
