What happend to Chinese imagrints when they arrived in angle island?

When Chinese immigrants arrived at Angel Island in the early 20th century, they faced rigorous inspections and questioning by Immigration officials. Many were detained for long periods, sometimes weeks or months, as authorities sought to verify their identities and eligibility for entry under the restrictive Chinese Exclusion Act of 1882. The experience was often traumatic, marked by harsh conditions and uncertainty. Ultimately, only a fraction of those who arrived were granted entry to the United States, while many others were denied and deported.
