Answer: No. Section 106(a) of AC21 allows an alien to obtain an extension of H-1B status beyond the 6-year maximum period, when:
A. 365 days or more have passed since the filing of any application for labor certification, Form ETA 750, that is required or used by the alien to obtain status as an EB immigrant, or
B. 365 days or more have passed since the filing of an EB immigrant petition.
Once these requirements have been met, the alien may be granted an extension beyond the 6-year maximum on or prior to the date the alien reaches the 6-year maximum. Such extensions may only be granted in one-year increments, but may be requested on a single (combined) extension request for any remaining time left in the initial 6-year period. Requiring the filing of two extension petitions merely increases petitioner and CIS workloads, and has no basis in statute. In no case, however, may the total period of time granted on an extension exceed a cumulative total of 3 years. 8 CFR 214.2(h)(15)(ii)(B)(1)
