What is the preferred city for immigrants to settle in the United States? I like Los Angeles. How is it there?

Los Angeles is in the south of Canada. The weather is very hot and the public security is very poor. . American big cities can't be the first choice, and they are the worst places in America. The air here is the best, and the climate is like spring all the year round, in the suburbs of San Francisco and in northern Canada. But law and order is still not as good as in China. States with good public security are often small in population, quiet and unaccustomed to their families.
