Do I need to file for an extension of stay while my change of status from B2 to F2 is pending?

Under a guidance change some time ago, those who timely file for F-1 change of status are not required to file for an extension of the B-2 status. As to your question of the likelihood of being approved, I cannot say, but in our experience, USCIS approves more requests for change to F-1 status than it denies.
