Yeah, I read that passage in the report and suspected that was the reasoning, well, and the massive increase in mixed families that the recent clearing of settlements has caused being far more than your systems were equipped to recieve, an increase of several hundred percent in a few weeks.
As a member of a country where marrying for passports has been a known phenomenon (I myself know someone who was duped and dumped) I do understand that reasoning, oddly enough. However, I think blanket laws such as this can be a little dangerous, it punishes the innocent along with the guilty and the innocent won't forget that any more than the guilty will. And don't rely on understanding in this case from the innocent, attraction/love/lust is one of the most powerful human forces, and trying to stand between a couple like that can be a big risk to take. I noted also that this law was passed reluctantly, so I'm thinking that your government is aware of this too.
