Structured side-by-side cards for shipped visas — no invented difficulty scores.
O-1A vs EB-1A
Both are extraordinary-ability routes. O-1A is temporary work; EB-1A is a green-card petition. Evidence bars are related but not identical.
O-1A vs EB-2 NIW
O-1A emphasizes extraordinary ability for temporary work. EB-2 NIW emphasizes an endeavor of national importance for a green card — different legal tests.
O-1A vs UK Global Talent
Cross-jurisdiction comparison: US extraordinary-ability temporary work versus UK endorsement-led Global Talent. Not a Skilled Worker comparison — that route is not in Visa Engine yet.
