Scott Act (1888)

The Scott Act (1888) was a United States law that prohibited Chinese laborers abroad or who planned future travels from returning. Its main author was William Lawrence Scott of Pennsylvania. It was introduced to expand upon the Chinese Exclusion Act passed in 1882. This left an estimated 20,000-30,000 Chinese outside the United States at the time stranded.
