Can we file LCA while H1 extension in progress

[megaamar]

Hi Folks,

My H1 is expired and My employer filed for extension on 11th sept 2013.
Now, my project is about to end in 31st dec 2013.
Can my employer file another LCA while my H1 extension in progress, so that I can work for other client and/or location?

thanks and regards,
