re: mallu2u
I agree with soapbox, some center takes lots of time for processing new h1/ h1 transfer/ h1 exten after H1 premium process introduce.
By law your application shoud reach ins one day before your current visa expire, but I wouldn't wait and start h1 extention ASAP with valid date from december (when your cureent h1 expire)
I hope this will help.
