On the issue of K 1 US visa

Question1-You can't work, and your chances of doing so are very low, because K 1 is an immigrant visa, which is issued to people who want to get married and get along with their fiance in the United States (if you just want a marriage certificate, you can do it in that country). Your fiance doesn't live in the United States, just get married in China, so the Immigration Bureau will doubt your motivation and necessity of coming to the United States. K 1 is the one that requires the least information among all visas, and the examination of the applicant's marital authenticity is more strict. Therefore, even if you find someone to help you hand in the documents in the United States, your fiance must not only be an American citizen, but also have a tax record in the United States for more than one year. Otherwise, you have to find someone to vouch for it, and even ask your fiance to show proof of residence in the United States. It will make the visa that is already difficult more complicated. According to your description, he was probably born here (America) and has never lived in America. In this case, unless you have a very special and convincing reason, the Immigration Bureau will not send you a K 1.

Question 2-Haha, I'm sorry, I meant no harm. I just think it's fun to look at the problem, as if I were playing a word game. As I said, K 1 is an immigrant visa for "coming to the United States to marry an American citizen". It doesn't matter how many days you stay in America, what matters is that they give you 90 days to arrange and complete the wedding. Is it not a "girlfriend" visa to enter the country as a fiancee and not get married? Therefore, if you don't finish your wedding, whether you are still in the United States or not, your visa will be automatically cancelled after 90 days of entry, and it will be more troublesome to apply for a visa after leaving the country, because it proves that you "cheated" the immigration office and you want K 1 to get married in the United States. Of course, you can also say that you gave up this marriage because it was inappropriate, but it will still have a negative impact on your future application to the United States. Also, after the wedding, you usually apply for a green card. You have only been in this country for less than 90 days. How can I change my green card? If it is not changed, it will not meet the purpose of K 1 visa.

I don't know what your intention is to come to America. If you just want to visit for a short time, maybe you can get married in China and get a tourist visa, that is, you want to come to the United States with your husband or something. You are married to an American citizen, so it shouldn't be so difficult to apply for such a visa.
