H1b amendment regular processing time

Hi Saurabh,

My h1b amendment was filed around July 25th , 2023 under regular processing. Its still pending , My employer is not willing to upgrade it to premium.
How long it might take to get approval under regular processing now-a-days?
can we do h1 transfer while amendment is pending? Are there any concerns related to travel outside usa or job change or job loss during the period amendment is pending? Thank you for your help in this regard.

Regards,
Ruchi
