Hello Ahad,
Sorry for taking so long to respond. I have not been on this forum for some time now. Yes, the only way to find out when your number will be current is looking at the DOS visa bulletin board. Please note that DV2010 ends this september. So you may need to double check last year's bulletin to estimate when your CN becomes current. December 2010 would be too late. Here the link to check past bulletins. Hope this helps.
