Check whether a company holds a UK or Netherlands work-visa sponsorship licence. The register lists official registered legal entity names, not brand, product, or trading names. If the user provides a brand name, product name, or website, first determine the company's registered legal name (via web search, the company's own website, or the relevant companies register) and pass that. Tolerates minor typos but not brand-vs-legal-name mismatches. Returns licence routes, ratings, locations and register dates. If results are ambiguous or none are found, refine the legal name and try again. For exploring or filtering many companies, use search_sponsors instead.
