I am on h1b visa. My wife has been on following visas:
H4: jan 2007 - nov 2007 (11 months)
L1: Dec 2007 - Sep 2008 (10 months)
H1B: Oct 2008 - Apr 2009 (7 months)
H4: 3 months in 2010
H4: Jan 2014 - present (2 months)
Rest of the time she was in India.
I understand that h1b time from previous petition can be recaptured. If she does a change of status to h1b, how much time will she get? Is it too late to use the old h1b from 2008?
