Question related to EB2 - 485 Filing and EAD - Experts please comment

[nycwork]

Hello Experts,

Please provide your guidance on my case.

Thanks for your help.

Case details:

H1B Valid until Dec -2012 currently 7th Year

H1B Stamped recently and valid until Dec-2012

Labor and -140 Approved with PD DEC 2009

I'm planning to file my 485 now and would like to know what would be the impact on my case since there are news of dates for EB2 retrogression back to Aug 2007

• If I file my 485 now - how soon I would be getting EAD and AP
  
• If the dates goes back and I go back to my home country and get married - would I be able to apply for EAD for my spouse after getting her on H4 visa here even if the dates moves back to Aug 2007
  
• If I travel to india after my H1B stamping period (DEC 2012) passes and I already have my new H1B extended - Can I come back using my EAD and AP to avoild another visa stamping and my spouse can come on H4 Visa
  
• Are there any cases where EAD, AP and GC are all dispatched together in a month time?
  

Thanks
