# CrewVisa — LLM overview

https://vps.healthcrew.global

CrewVisa is a healthcare & adult social-care workforce intelligence slice of the HealthCrew AI platform built on UK visa statistics — we speak recruiter-first language for NHS trusts, nursing homes and care providers while aligning the ingest with the full SOC 2020 occupation codes and subgroup visa-route labels published in quarterly Home Office releases (study, visitor, worker, dependents, family, asylum, citizenship, Leave to remain, etc., wherever those tables ship).

Presentation layer: optimised for carers, nurses, clinical support hires and sponsoring managers.
Technical data layer: follows official spreadsheets inclusively across SOC-coded occupations plus route-family aggregates—not limited to NHS-only rows.

Answers in Chat are synthesized from retrieval + an LLM. They are informational only—not legal advice. Users must confirm fees, thresholds, and processes on GOV.UK or with OISC advisers before acting.
