Enlisting vs Commissioning
Enlisted path: immediate eligibility (1 day active duty). Officer path: must complete commissioning first, then 1 day triggers eligibility.
Officer Commissioning
ROTC (college-based), Officer Candidate School (OCS), West Point Academy. Each has own timeline (2-4 years).
Timeline
Commissioned → Active duty 1 day → Eligible for citizenship. Much faster than 5-year Green Card route.
