H1B stamping while L1B valid

Can someone help me with this query.I am already holding a LI B which is valid till 2018. If I am going for stamping in Canada for 1st time H1B and get 221g, can I still get the passport back in hand and travel back to US till they complete the admin processing.

Both are independent. One does not affect the other.

Thanks for replying . You meant to say I can still travel back to USA in l1b if there is extended admin processing for h1b right ?

If your L1B visa is still valid, you can travel.
