How long does it take for my fiancee to visit relatives in the United States to get a visa?

In the laws of China, a fiancee is not a relative.

American immigration law allows American citizens to apply for a visa (K 1 visa) for their overseas fiance (wife) to get married in the United States. Non-immigrant visa, obtained at the American Consulate in Guangzhou. The application period is about 8-9 months. K 1 The visa is valid for 90 days. Within 90 days, the overseas fiance (wife) must marry the American applicant, otherwise his identity will be invalid. Applicants for unmarried (husband/wife) visas can only be American citizens. Among them, the applicant must prove that the two parties have met in the past two years and provide evidence, otherwise he is not eligible to apply for K 1.
