I have to do an intership of at least 2 months this summer, and at least 4 months abroad in my whole cursus.

So I'd like to do my internship in the UK this summer, possibly in London. If you have any tip to find one, it could help me a lot !

(and the best would be something related to computers, since I'm in a computer engineering school)

I can't help you with finding internships but you have my support. I did a study abroad in England when I was 19 and it was one of the best things I ever did. So when I see a young'un whose opportunity comes a-knockin', I say go for it no matter what because you never know when you'll get the chance again.

Good luck!!
