Many Western states also enacted discriminatory laws that made it difficult for Chinese and Japanese immigrants to own land and find work. One of these anti-Chinese laws was the Foreign Miners' License tax, which required a monthly payment of three dollars from every foreign miner who did not desire to become a citizen. Foreign-born Chinese could not become citizens because they had been rendered ineligible to citizenship by the Naturalization Act of 1790 that reserved naturalized citizenship to "free white persons".
