Do you need a face-to-face visa to get a green card after fingerprinting the American green card?

not necessarily. According to the relevant public information, there are two cases where the interview can be omitted, for example, the applicant obtained the green card through marriage, and the marriage has lasted for at least 2 years. Or the applicant obtained the green card through special immigration programs, such as EB-1A and EB-1B.
