Attended h4 interview on august14,2020

Quick question. Visaofficer asked all questions about spouse related and I answered perfectly. He took my wife i797 and marriage certificate and finally VO said " for now I am giving your passport, we will contact you"

  1. VO took documents, is it positive sign?
  2. Mine is emergency appointment, do they will do any process fastly.
  3. VO did not issue any 221g, is this also positive sign
