It seems that many people who go abroad are refused visas because of their immigration tendency.

1. The tendency to emigrate is simply that your ultimate goal is to emigrate. In your case, it means that two people are not in love, but they made a deal first to convince the embassy that they really love each other and will get married in America. If they succeed in obtaining visas, China people can come to the United States. Of course, they will only get a visa if they get married again, and then divorce (because they are not in love, just to go abroad), even if it is done. In this process, Americans are just tools to realize China's desire to emigrate. Of course, sometimes it's not a deal between the two sides, but maybe Americans are used by China people. This is the immigration trend.

2. In principle, it has nothing to do with money status, but if that China person has nothing, it may increase your suspicion of immigration tendency. In fact, the Immigration Bureau is like a case-handling agency. All you have to do is provide all the evidence that may prove that the two people love each other, so that the motivation of immigration tendency can be ruled out. As for the possibility, it's up to you.

Ten years is impossible. My personal experience is half a year. But there will be a month or two, a year or two, depending on the speed of review. If the visa is rejected, it will also give a message, and it will definitely not wait for ten years. But after you go abroad, you will have time to visit you, and the time will be longer, if you want to win permanent residents.

4. Supplementary question: Generally, you must apply for immigration before getting married. Unless they want to live in China.
