PIMS (Petition Information Management Service) update timeline

[Aarav27]

Hello,

Just wanted to know if anyone is aware of PIMS database update timeline these days.
I am planning to get my visa stamped in April 2017 and have recently got transferred my visa to a new employer in January 31st, 2017.
Just curious to know if I can take some steps ahead of time to avoid delay during stamping process.

Thanks in advance!
