The Chinese Exclusion Acts were passed to keep Chinese workers from immigrating and taking American jobs. This is the first and only group of people that were excluded from immigrating based upon their country.  The Acts meant the Chinese could no longer come to the U.S., with few exceptions. Some still came with fake documents, known as "paper sons," pretending to be related to other people already here. The Acts affected where the Chinese migrated after the Civil War, and were in effect until during World War II.

An Act to execute certain treaty stipulations relating to Chinese.
Whereas in the opinion of the Government of the United States the coming of Chinese laborers to this country endangers the good order of certain localities within the territory thereof: Therefore,

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That from and after the expiration of ninety days next after the passage of this act, and until the expiration of ten years next after the passage of this act, the coming of Chinese laborers to the United States be, and the same is hereby, suspended; and during such suspension it shall not be lawful for any Chinese laborer to come, or having so come after the expiration of said ninety days to remain within the United States.
SEC. 2. That the master of any vessel who shall knowingly bring within the United States on such vessel, and land or permit to be landed, any Chinese laborer, from any foreign port or place, shall be deemed guilty of a misdemeanor, and on conviction thereof shall be punished by a fine of not more than five hundred dollars for each and every such Chinese laborer so brought, and maybe also imprisoned for a term not exceeding one year.
SEC. 3. That the two foregoing sections shall not apply to Chinese laborers who were in the United States on the seventeenth day of November, eighteen hundred and eighty, or who shall have come into the same before the expiration of ninety days next after the passage of this act, and who shall produce to such master before going on board such vessel, and shall produce to the collector of the port in the United States at which such vessel shall arrive, the evidence hereinafter in this act required of his being one of the laborers in this section mentioned; nor shall the two foregoing sections apply to the case of any master whose vessel, being bound to a port not within the United States, shall come within the jurisdiction of the United States by reason of being in distress or in stress of weather, or touching at any port of the United States on its voyage to any foreign port or place: Provided, That all Chinese laborers brought on such vessel shall depart with the vessel on leaving port.
SEC. 4. That for the purpose of properly identifying Chinese laborers who were in the United States on the seventeenth day of November eighteen hundred and eighty, or who shall have come into the same before the expiration of ninety days next after the passage of this act, and in order to furnish them with the proper evidence of their right to go from and come to the United States of their free will and accord, as provided by the treaty between the United States and China dated November seventeenth, eighteen hundred and eighty, the collector of customs of the district from which any such Chinese laborer shall depart from the United States shall, in person or by deputy, go on board each vessel having on board any such Chinese laborers and cleared or about to sail from his district for a foreign port, and on such vessel make a list of all such Chinese laborers, which shall be entered in registry-books to be kept for that purpose, in which shall be stated the name, age, occupation, last place of residence, physical marks of peculiarities, and all facts necessary for the identification of each of such Chinese laborers, which books shall be safely kept in the custom-house.; and every such Chinese laborer so departing from the United States shall be entitled to, and shall receive, free of any charge or cost upon application therefor, from the collector or his deputy, at the time such list is taken, a certificate, signed by the collector or his deputy and attested by his seal of office, in such form as the Secretary of the Treasury shall prescribe, which certificate shall contain a statement of the name, age, occupation, last place of residence, persona description, and facts of identification of the Chinese laborer to whom the certificate is issued, corresponding with the said list and registry in all particulars. In case any Chinese laborer after having received such certificate shall leave such vessel before her departure he shall deliver his certificate to the master of the vessel, and if such Chinese laborer shall fail to return to such vessel before her departure from port the certificate shall be delivered by the master to the collector of customs for cancellation. The certificate herein provided for shall entitle the Chinese laborer to whom the same is issued to return to and re-enter the United States upon producing and delivering the same to the collector of customs of the district at which such Chinese laborer shall seek to re-enter; and upon delivery of such certificate by such Chinese laborer to the collector of customs at the time of re-entry in the United States said collector shall cause the same to be filed in the custom-house anti duly canceled.

Such list shall show the names of such passengers (and if accredited officers of the Chinese Government traveling on the business of that government, or their servants, with a note of such facts), and the names and other particulars, as shown by their respective certificates; and such list shall be sworn to by the master in the manner required by law in relation to the manifest of the cargo. Any willful refusal or neglect of any such master to comply with the provisions of this section shall incur the same penalties and forfeiture as are provided for a refusal or neglect to report and deliver a manifest of the cargo.
SEC. 9. That before any Chinese passengers are landed from any such line vessel, the collector, or his deputy, shall proceed to examine such passenger, comparing the certificate with the list and with the passengers ; and no passenger shall be allowed to land in the United States from such vessel in violation of law.

Video Clip Above: “During the period after the Civil War, Chinese laborers in America were plentiful, hard-working, and inexpensive to hire.  They were willing to do almost any job asked of them, often at great risk to themselves.  Because of this, and the fact they dressed differently, ate differently, and spoke a language that sounded so strange to the American ear, the Chinese worker was soon seen as a threat to white labor.  That threat led to fear, and that fear became the impetus for the Chinese Exclusion Act passed by Congress in 1882.  This act prohibited immigration of Chinese laborers into the United States.  The Chinese are the only nationality to have a law specifically written, prohibiting them from immigrating to the United States.” -From Honor and Duty: The Mississippi Delta Chinese, A Three-Part Documentary Series, narrated by E.
