Case in 221(g) after being approved by the VO at window.

[swasti]

I am transitioning from f1-h1b and gave interview for the same on 2 January, 2018 at new delhi. The vo officer told me its approved. But its under administrative processing since then. And today when I emailed the consulate they told me it has gone to 221(g) and that no further documents are required.

Is there anyway to know that how long it will take to process this?
how to know the color of 221(g)?
And is administrative processing same as 221(g)?
