That's a positive sign. Security has probably started behind the scenes. It'll almost always show not started until the very end. In fact 'in progress' might even mean security screening.I'm not quite sure about it. I called an agent last week, she told me that my eligibility were passed but didn't mention about the time. I asked her double check because it was Recommended Passed in Sept, she again told me now it is passed. But my concern is why the security hasn't been started.
I was so hopeful in November after a lot of movement in October, but it's been silent since then
