I replied that this was was not so.
Now you link to a US law that shows that in fact, immigration was allowed from 24 to 65.
You do understand that limiting immigration to whatever the law provides is not in fact stopping all immigration, don't you?
The Immigration Act of 1924, or Johnson–Reed Act, including the National Origins Act, and Asian Exclusion Act (Pub.L. 68–139, 43 Stat. 153, enacted May 26, 1924), was a United States federal law that set quotas on the number of immigrants from certain countries while providing funding and an enforcement mechanism to carry out the longstanding (but hitherto unenforced) ban on other non-white immigrants.
The law was primarily aimed at further decreasing immigration of specific groups of Europeans, including Italians, Greeks, Poles, Slavs, and Eastern European Jews.
[1][2][3][4] The law affirmed the longstanding ban on the immigration of other non-white persons, with the exception of black African immigrants (who had long been exempt from the ban).
Thus, virtually all Asians were forbidden from immigrating to America under the Act.
