Lets say that there is increased vetting. And lets say that vetting process involves in depth questioning of ALL prospective immigrants.

Now lets also say that the Immigration officer is taught to specifically look for signs that perhaps the prospective immigrant sitting in front of her or him may not have been exactly truthful when responding to written questions, on, for example, gender equality. Perhaps a hint would the prospective immigrant's wife covered in a head to toe black veil. 

Now that could be the woman's choice, so the immigration officer probes a little further. Maybe asks the woman some questions, and checks the man's reaction.

Does this sound invasive? So what?

We either want to retain and build on the liberties and freedoms we have, including by bringing in those who share that aspiration, or we watch it erode as we continue to let any and all in.
