I need your help plz...

[TeeB2014]

I am a US Citizen and I petitioned for my wife GC in August 2014. We live together and my wife Bio metric is Oct 10,2014. My wife I-485 is RFE.. (USCIS needs our Joint Sponsor last federal tax return) and we are currently working on getting that to them asap. My I-130 is Initial Review. Therefore we are in the middle of this entire GC process. Unfortunately I recently lost my job (today ) and am currently looking for a new one asap. My question :

(1) Should I tell USCIS about my current job lost asap?
(2) Will this affect our case?
(3) Do I need to refile any of our papers?
(4) My wife wants to start school and also work, what is the processing time for her EAD?

1. No.
2. May be. It depends upon how much of your income was counted in I-864 and how much of that of joint sponsor.
3. No.
4. You can look at the processing times at http://www.immihelp.com/processing-times/
