Options for filing CP from india for 221g Administrative Processing struck cases

[nycwork]

Hello Experts - Please suggest your inputs and directions on my case.

I am struck in India with 221g Admin Processing Blue for the past 4 months and my GC priority date is current now with February Visa Bulletin

• Labor and 140 Approved with priority date of Dec 2009
  
• 7th Year of H1B - Expiring in Nov 2012
  
• Visa pending with 221g blue in India Consulate since October 2011
  

Available Options:

• Wait until Administrative Processing is completed - already 4 months of waiting;looks a security check as there are no client or vendor verifications and the response is standard [waiting for dept of state to clear the processing]
  
• Can I apply for CP (i824) from India and once my visa struck in 221g gets approved, Can I go back to US and then file for I-485 and if this is possible are there any issues or particular stage of CP which will prevent from filing i-485)
  
• How much time does it take for CP and different stages ( i-824, NVC, packet 2, packet 3 etc)
  

Thank you all,
