Ellis Island Immigrant Inspections: The Gateway Process (1892–1954)

Mandatory Inspections for 12+ Million Immigrants

Before entering New York City, every arrival at Ellis Island underwent:

1. Medical Examination (U.S. Public Health Service)

Doctors screened for contagious diseases in a rapid "six-second exam" (chalk marks on clothing indicated issues):

• Trachoma (eye infection – leading cause of detention)
• Tuberculosis
• Cholera, smallpox, yellow fever
• General physical/mental fitness

Sick immigrants were detained in hospital wards until cured or deported.

2. Mental/Legal Inspection (Immigration Officials)

• Intelligence/psychological screening (simple puzzles, questions)
• Verification of identity, nationality, occupation, sponsors
• Exclusion criteria: contract laborers, anarchists, polygamists, "likely public charges"

3. Legal Interview

29 questions (name, origin, destination, money, relatives, criminal record, etc.). Answers cross-referenced with ship manifest.

Outcome

• ~80% processed in 3–5 hours (ferry to Manhattan)
• ~20% detained (days to months) for medical/legal review
• ~2% deported

Legacy

Ellis Island was a filter for "healthy, law-abiding, self-sufficient" immigrants—shaping America's demographic fabric.
