Will Britain be notified of visa refusal?

Generally, there is no notice after the visa is refused in the UK. Only after you get your passport can you directly know what the final result is. If you refuse the visa, there will be a paper refusal letter in it, but don't worry too much. If you apply for a visa after being rejected in Britain, as long as the binding force is increased, the chances of passing it are also great.

When to sign again after rejection has nothing to do with time. The key is whether your binding force is stronger than last time. If the binding force is more than last time, you can sign it again 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.
