What evidence do I need to gather before challenging my inclusion in a Purple Notice?

Compile documentation establishing your legitimate activities in any sector referenced by the notice — for example, if the notice concerns smuggling techniques in shipping, evidence of lawful import-export business operations is essential. Gather travel records, employment history, and any correspondence with authorities in the requesting country. If you suspect political motivation, collect evidence of your political activities, asylum applications, or prior persecution. Court documents from any related proceedings — especially acquittals or case dismissals — are critical. Contemporaneous evidence predating the notice carries greater weight than materials assembled solely for the challenge, so preserve records immediately upon learning of potential inclusion.
