This question about somebody who has been refused a visa once has been marked as a duplicate of this question about dealing with multiple visa refusals. It was closed by "community", whatever that means.
The question is clearly not a duplicate, since it is about a single refusal, not a repeated series of refusals. The one normal user who voted to close the question made a mistaken edit to the title of the post, confusing "failed an exam three times" with "had a visa refused three times". Perhaps that was the basis of the "community" closure, though the edit was corrected before the "community" clese vote.
This question should be reopened.
Also, what does it mean for "community" to vote to close?
