H1-B extension with new work location

[gmandal]

Hi,
My employer has filed for h1b extension with a new working location. Now I understand that I as per USCIS law I can continue work for 240 days after my expiration of I94.
Could anybody please let me know if I am allowed to work in the new working location or I am only allowed to work in my current working location for 240 days.
Thanks in advance.
