Summer REUs for non-US citizens

<p>Hi everyone, I'm a first year undergrad in the UK doing maths and economics and was wondering if there are any REUs for students in my situation.</p>

<p>I've been looking on the AMS website, and most of them are only for US citizens. I am quite interested in doing research in mathematics, and if anyone knew of any summer opportunities that I could take advantage of either in UK, US or Canada, that would be fantastic.</p>

<p>Thanks a lot!</p>
