Here is an overview of my case:
Dec 21, 2018: interview for H1B at the US Consulate in Chennai; received a blue 221g asking for a couple of docs
Jan 7, 2019: submitted requested docs via email. (Status on CEAC was admin processing updated 21 Dec 2018)
Jan 29, 2019: received an email requesting for my passport to be submitted to VFS; submitted the same day
Feb 1, 2019: CEAC status is still Admin processing but date changed to Feb 1, 2019
Is there a chance for my visa to be rejected or delayed further or can I assume it's approved?
