How does internships work at your company/country?

Hi!

I’m interesting in what the policy for doing internship at your studio or in your country/area, are in general. I’m a technical artist student at The Game Assembly (http://www.thegameassembly.com/), Sweden, and as part of my education we finish off with a 20 week long internship.
Now, tomorrow we having a meet and greet with around 35 companies, most of them coming from Sweden, Denmark, Norway and one from UK. I’m very interested in doing my internship abroad and are therefore wondering if any of you know the guidelines for international students, wanting to do internship at your company/in your country. We had few students doing their internship around Europe and one in Canada.

And if you have any feedback regarding my portfolio, you are welcome (some of you have already given me awesome advice):
