This site's "difficulty" is an explainable composite score (v1): it first checks whether the pathway is currently obtainable, then weights five dimensions — eligibility threshold, numerical limits and waiting, burden of proof, statutory financial threshold, and procedural dependency — into 0–99. 100 is reserved for pathways that official evidence shows are fully closed to new applicants. Every dimension carries facts, rationale and official sources; if any dimension is missing, no total is shown. This is an editorial assessment by this site, not a government score or an approval probability; annual issuance counts are shown as separate facts and never converted into the score.
