>On March 11, 2016, the Department of Homeland Security published a final rule allowing certain F-1 students who receive science, technology, engineering, and mathematics (STEM) degrees, and who meet other specified requirements, to apply for a 24-month extension of their post-completion OPT. The 24-month extension will replace the 17-month STEM OPT extension previously available to STEM students (see 73 FR 18944). Eligible students may now apply for a 24-month STEM OPT extension.

Does that mean the H1B validity now also starts before October 1?
The 17 month extension would have ended October 1 (traditionally the H1B start date). So I am curious what happens if one applies for and is granted the H1B in their third year under OPT.
EDIT: Apparently the duration was changed recently. See comment below.
