The American visa was refused. How long does it take to apply again? Do you have to pay again? Is the cost the same as the first time?

The visa fee charged by the embassy still needs to be refused first, and then paid after the next signing. Moreover, if the binding force of the United States is increased after the refusal, it can be re-signed at any time. If you don't change anything, that is, the binding force remains the same as last time, even if you sign in 10, the result will still be rejected, so when you can sign again after being rejected has nothing to do with the time, mainly depending on whether your binding force has increased compared with last time. As long as you add it, you can sign it again right away. Please consult the Internet for specific questions. They are state-owned institutions specializing in visa refusal and re-signing. They have been established for more than 30 years, and many applicants who refuse visas in the United States go through them. Wish you success!
