An illegal entry investigation must document foreigners' entry routes, residence, witnesses, and enablers to build a complete case file aligned with the Immigration Act. It requires structuring evidence collection, witness interviews, and three specific reports for legal handover to border police.

Illegal entry cases require three investigation reports: the initial investigation report, the prosecutor submission, and the border-police handover report. These satisfy legal compliance requirements and ensure proper detention order processing under immigration law.

To identify missing evidence in an immigration investigation, systematically review the case file against required documents, witness statements, and official records. Structured checklists help highlight gaps in route documentation, residence proof, and enabler identification before legal submission.

Witness interviews in an illegal entry case should cover the foreigner's entry route, residence details, and any enablers who facilitated the border crossing. Structured questioning ensures statements satisfy legal requirements for the investigation and prosecutor reports.

Illegal entry investigations require a formal handover report to border police as part of the three-report progression. This ensures the detention order and case file comply with immigration law protocols for transferring suspects and evidence.

A compliant illegal entry case file requires references to the Immigration Act and related legal elements. These references ensure the investigation, witness interviews, and detention orders align with Thai immigration law throughout the case progression.
