How to find out the reasons for the refusal of a visa in the United States?

There is no reason for refusing a visa in the United States. This is an illegal act. The embassy will not disclose the reasons why any applicant was refused a visa. Some intermediaries said that they could check the reasons for refusing visas from the embassy, and its authenticity was difficult to determine. Think about it. Is it possible to let embassy staff risk being fired for spending so little money? Moreover, if the embassy finds that you entrust others to retrieve files from the embassy system, the consequences will be very serious, which will lead to lifelong refusal!

And the embassy has been cracking down recently. I heard that many customers have been told by the embassy to refuse visas for life after being found to entrust others to shift gears recently, and now they are on the cusp again!
