Discuss the following Hypothetical: The Immigration and Naturalization Service has been mandated to oversee, among other things, employment of undocumented aliens. Regulations mandate that all employers maintain a form I-9 for each employee, indicating the employee's immigration status. Generally these documents are kept with a Human Resources file. If the form I-9's are kept separate from other employment documents, does the INS have the mandate to search those other documents and why.
