Working on H1B with multiple approved petitions.

Hello,

I have recently come to USA and have situation. Any advice would be of great help.

I am working with employer X who filed my H1B. Meanwhile I got another opportunity with employer Y who filed for an H1B trasfer and got a new approved I797. However, later I decided to stick with employer X and have come to USA for the first time on my original VISA with employer X. I got admited on PoE and recieved I94 as well.

1. Is my current status valid as my most recent petition is with employer Y while I am working for employer X?

2. Is there any possibity that since I have two petitions I will be issued two I-94, which can cause an issue in my working status?

Thanks in advance!
