Source registry entry: state-sos; Source registry entry: state_contracts; Reading records: units, source coverage, wage gaps, entity links, and inference limits. XH1B dataset description: Registered-agent and registered-office fields identify who receives legal notices. Texas, for example, permits registered-agent service companies to represent businesses. Shared agent or address details are review leads. They do not, by themselves, establish shared ownership, a shell company, or a violation. State rules vary.; XH1B dataset description: State government award and vendor records. Connecticut Open Expenditures records payments, including grants. Payment totals stay separate from contract awards. Record identity fields vary by source; amounts and descriptions do not set identity.; These are the site's review methods, not validated predictions of wrongdoing.
