Permanent residence
OPT is temporary training authorization. USCIS also describes a cap-gap extension when a timely H-1B petition and change of status are filed. Permanent residence, if any, depends on a later immigrant category, not on OPT itself.

Family
F-2 dependants remain tied to the principal F-1 status. The OPT page focuses on the F-1 student’s employment authorization rather than expanding F-2 work rights.

Citizenship
The OPT sources do not establish citizenship eligibility.
Processing time
For initial post-completion OPT, USCIS says you must apply after the DSO enters the recommendation, within 30 days of that recommendation, and no later than 60 days after degree completion (and up to 90 days before completion). Regular OPT is up to 12 months per education level; STEM OPT can add 24 months.
