What is the reason for the United States to reject F4? So if you give blue paper, will it be wasted after waiting for more than ten years?

The blue bar is not a direct refusal. It is just a supplementary material or a back tone. If the supplementary materials or replies pass, the visa will be issued, not for nothing! It's only white to refuse a visa directly, but there are not many people who refuse a visa directly, unless there are serious problems, such as fake marriage, a history of cheating the immigration bureau and a serious criminal history.
