An American man wants to marry a China woman. What procedures does this American man need to complete the whole marriage process?

I am in America, and many relatives have applied for wives to come out. The lawyer's fee he said does not exist. In fact, it is very simple for citizens or long-term residents to apply for spouses to come to the United States. First, he has to submit an application to the US Immigration Bureau, then wait for an appointment, during which he has to provide sufficient income proof, and finally notify the forensic doctor for examination. Spouses can choose to get married in the United States or China. In fact, the most important thing for the US Immigration Service is that in the United States, the spouse has enough income to take care of the applicant, and there is no possibility of fake marriage with the applicant.
