In fact, refusing a visa is not terrible. As long as your binding force is greatly improved compared with the last time, you can pass it completely, instead of refusing the visa several times as mentioned on the Internet.
Refusal only means that your binding force can't reach the historical stage required by the embassy, just like we passed 60 out of 100 in TOEFL. Last time you refused the visa because your binding force did not reach the minimum passing line of 60 points in the embassy, so we should try our best to improve our binding force and raise our binding force score.
In fact, whether the visa is passed or not mainly depends on whether we can convince the visa officer that we will definitely come back after studying in the United States. If the visa officer believes that we will definitely come back after studying in the United States, he will give us a visa!
