Now, I want to apply for the UK visit visa to visit my friends in London for a weekend.
Let know them about it definitely in the section for additional information.
You should have
- Good savings, really good and evidence of that
- Ask university for special reference where it is written that you are currently a full-time student. In my county each university can make such a reference, most probably your university does either.
- In the invitation your friends will send to you make sure to note that they invited you for the exact period of time and after this period they are going to keep studying or working.
I do not think that US visa refusal can somehow impact on UK visa application as they are two different counties. I also do not see any reason not to apply for now.
Good luck!
