How long should i wait after sending in i-130 and other immigration forms?

I sent our package with all the doents and evidence. How long after they receive it should we expect to receive a response? My work authorization runs out at the end of may. I sent in my renewal 765 too. Around when will i receive the extension? I dont want to be stuck without work. I also need the renewed one to renew my drivers license (which expires the same day by old work authorization does.
