H1B paystub from a different branch with a different EIN number

[samratt]

I am a physical therapist on H1b with a Homecare Company A since 2016. Recently I was transferred to a different branch (my work area/counties remained same as LCA) within the same Company A. However, the new branch functions under a different entity name Company B (EIN) and I got 3 paystubs with a Company B name. Both Companies are part of same corporation and does business under same name. My i94 and 797 is valid till Feb 2019. I told my employer and they started issuing the paystubs from Company A.


I need to explore my options to fix this. Any advise is appreciated.
