L1B to H4 visa - approval date


I got an approval notice for my H4 case today. My L1b visa got expired on 11-Jan-2013.  We filed the the extention well before that and the receipt date was 02-Jan-2013.   I was expecting the H4 visa to be approved from 12-Jan-2013. But the H4 approval notice says the H4 visa is valid from 08-Feb-2013 to 04-Sep-2015. 

There is a gap of 1 month from my L1b Expiry date and the H4 approval date. Is this a problem?



If your L1 extension was still under process then I think you should not worry you were not out of status.
