If it is difficult to find a job in Los Angeles, you can try New York and Chicago. Especially in New York, many Chinese have no legal status, so there is no delay in finding a job.
Most Chinese workers in the United States work for Chinese bosses, and these bosses are not strict about their identities. Unless local inspections are strict, the boss requires migrant workers to have legal status.
It is recommended that migrant workers in the United States apply for lawyer status, which is safer and more secure, and the cost is not too high. Lawyers in Los Angeles generally charge US$4,000-5,000, and lawyers in New York generally charge US$6,000-7,000, which is equivalent to 2-4 months' salary. With a legal work status, you can work legally for at least 4-5 years and even have the opportunity to apply for a green card.
