The final rule allows such F-1 STEM students who have elected to pursue 12 months of OPT in the United States to extend the OPT period by 24 months (STEM OPT extension). This 24-month extension effectively replaces the 17-month STEM OPT extension previously available to certain STEM students.

Dates: This rule is effective May 10, 2016, except the addition of 8 CFR 214.16, which is effective from May 10, 2016, through May 10, 2019.

You will be able to extend your OPT for an additional 7 months if you are already under 17 month extension, according to https://www.lexology.com/library/detail.aspx?g=8f1a6b74-ee2b-47d2-84ee-acc6239d4a32

dhanyabad hai information share garideko ma. ramrai bho !

Any OPT STEM Extensions that were submitted before May 10, 2016 will be valid for 17 months. To receive the additional 7 months of authorization, you will be required to complete a second application to USCIS.

If you have submitted your application to DSO last week, there is a chance that he/she has not posted your application to USCIS yet (considering my experience with the DSO advisers, it's like a government job for some).

But you have to wait until May 10, 2016 to apply for your 24 month extension.

Aba majyasney 7 months ko lagi pheri $380 tirnu parney, 17 months ko Asti ko mahina matra ayeko...teit
