L2-H1 and L2 back.. can I use old unexpired EAD card ?

[jinneebhat]

I have got my EAD card valid till June 2014. Now my employer wants me to switch to H1b visa. I plan to convert L2-H1 COS, and work for say 2 months, and thereafter apply I539 again.

In that case, do I have to apply I765/EAD card again? (even when my existing EAD card is valid)

You can use the same EAD.
