H1B transfer: Case Is Being Actively Reviewed By USCIS

I got an offer from xyz company. XYZ has filed H1B transfer under premium processing on August 29th 2022, it is been close to 5 weeks, the case status is " Case Is Being Actively Reviewed By USCIS". Attorney reached out to USCIS to inquiry on the case. USCIS said that the case is going under “security check”.

  1. Did any one has similar case status in the past?.
  2. If so how much time does it took to get approval/denial?.
  3. What might be the root cause for this status?. since it is premium it should be approved in 2 weeks.
  4. What is the best course of action that we can do here?.
