Promising practices bring us back to the core of our policy objectives. It's part of the existing policy suite and the existing regulations that in all ways these are meant to be authentic relationships that people entered into willingly. That's the core of the work that our visa officers have been doing for decades.
As I mentioned in the opening remarks we've taken measures to strengthen over time everything that we can do to make sure that these are actual relationships that people entered into willingly. You raised a point about the changing technology and the many ways that things have evolved over time. For us it comes back to the policy suite and the work that we do every day to ensure we have authentic relationships.
