Legal Question in Immigration Law in Georgia

I recommend referring to the following link: http://www.uscis.gov/working-united-states/temporary-workers/faqs-employment-authorization-certain-h-4-dependent-spouses

As an H-4 nonimmigrant, would my employment authorization be limited to just my H-1B spouse�s time under AC21? For example, if my H-1B spouse�s petition is approved for the remaining time left in the 6-year period of admission plus the one year under AC21 �� 106(a) and (b), and my H-4 status is granted the same period of time, how long will my employment authorization be valid for?

Your employment authorization expiration date generally will match your H-4 nonimmigrant status expiration date. USCIS may grant employment authorization for the maximum time allowed even if the AC21 �� 106(a) and (b) portion of your H-1B spouse�s extension is only for part of the full validity period. Under this scenario, your H-1B spouse�s extension has been granted under AC21 �� 106(a) and (b), so you would be eligible for employment authorization for as long as your H-4 status is valid.
