L1B-L1A conversion/extension denied, can I work in US until I-94 end date?

USA L1, L2 Visa

Hi,

If a Blanket L-1B to L-1A conversion and extension (applied together) is denied after an RFE, can I continue to work legally in the US until the I-94 end date (December 2015)? The visa expires October 2013. The petition itself did not have an end date, probably because it was a Blanket petition.

 

Thanks for your insight!
