If you are refused a visa to the UK, will the visa bureau notify you? Or do you have to wait until you get your passport to find out?

There is usually no notification after the UK visa is refused. The final result will be known only after you get your passport. If the visa is refused, there will be a paper refusal letter in it, but it is not necessary. I'm too worried. When I apply for a visa again after being refused by the UK, as long as the binding force is increased, the chance of approval is also very high.

When to sign again after being rejected has nothing to do with the time. The key is to see whether your binding force has become stronger than last time. If the binding force has increased compared to last time, you can sign again at any time.

If you don’t change anything, that is, the binding force has not changed at all compared to the last time, even if you apply for the visa in 10 years, the result will still be rejected. So when can you enter again after being rejected? Signing has nothing to do with time, it mainly depends on whether your binding force has increased compared to last time. As long as you add it, you can sign again immediately.
