employment letter needed for I485?

I submitted an employment letter for my EB2 NIW but I might be changing jobs soon. Do I also need an employment letter for my I485?

to crazybear619:

Nope, you should not need that for i-485.

to Calvin:

But how can i demonstrate that I am employed without an employment letter? Won't that create an RFE?

to crazybear619:

You dont need to demonstrate that your employed. NIW is self-petitioned. People can change jobs. :):)
