Q w/ premium processing

[immihelp]

Hi,

I need your help! We e-filed I-140 using Premium processing and got an approval notice e-mail the next day before they even got the supporting documents.
Have you ever heard abou this? Do you know what is going on?

Thank you

I have not heard about this before. I am not sure what is going on.

In fact, it may not be approval notice. It may be just receipt notice. Did you check it properly?
