Chilean miners, merchants and adventurers were among the first to respond to the California gold rush with the first group arriving by sea in 1848. News about the rush arrived in Valparaíso in September 1848 and the first group of Chileans arrived in California in late October of the same year. 1500 Chileans arrived in San Francisco in 1848. In total, Chile issued about 6,000 passports for travellers to California, but this does not reflect the number of migrants as many abandoned the country informally and Chile found little use in attempting to regulate and register the emigrants.
