Receipt date Jan 8 transferred from California to Vermont

Hello Anil,
Thanks for the amazing forum… My date is Jan 8, 2019. Originally filed at California and transferred to Vermont on February 1st. Vermont center shows processing time around 2.5 months.
Unclear to me is… The timeframe will be 2.5 months from January 8th or February 1st?

Count the Vermont processing time from the date your case was transferred to Vermont i.e. Feb 1, 2019.

You can expect to get your H1B approval by April 2019 third week end.
