Package arrived at the CA center on 12/10.
Receipt was never received and online status was not available either.
Called the 800 number on 1/2 and got a repsonse from the CA center in 40 days.
Dropped all classes based on the recommendation of ISO.
No additional documents requested.
Surprisingly got the approval letter today and the case was actually approved
on 3/1.

Hope this is a good news for those who are still anxiously waiting. Good luck
to you!
