Where can I check the visa refusal records in the United States?

Where can I check the visa refusal records in the United States? The embassy will have a record. But the most important thing is to find the reason for refusing the visa. In fact, there is no need to be too entangled in the issue of visa refusal in the United States. My cousin's application for a visa was rejected three times. Rejection seems normal. It's a good choice to find a hard-wired agency to sign for you. I know that there is an organization that specializes in refusal and re-signing. It is said that this family has some government background, and many people who were refused visas signed there. The point is that they have acquaintances in the embassy. One of my relatives later found the "Yijia Yimei. com" and soon the visa was successful. This one is a little expensive.
