Ask HN: Internships - Opportunities and Questions

Dear HN, I am a British student studying in the UK and following experiences with both an IT Corporate and a startup, I am exploring potential opportunities for the summer ahead. As such I was hoping HN members could both answer a few key questions and also advise on and suggest internships and technology schemes around the world. 1) Can non-US Students undertake internships (join startups on a temporary basis) without a complicated visa application process? if no, do any firms offer experience to non-US Citizens helping with visa approval. 2) Outside the US, are there any other regions (excluding europe) with a number of startups which offer experience to Citizens of the UK/Europeans. 3) Apart from the Beckman Center for Internet & Society (http://cyber.law.harvard.edu/node/7315), are there any other technology related academic programs for non-US Citizens around the world? 4) For UK and European-based firms who offer internships/experience - are they all pure-coding jobs? - (I am aware of job sites such as Enternships & WorkinStartups, but am interested just in case some firms are not aware of these sites but have opportunities available) I appreciate this is quite an extensive collection of questions and whilst I am clearly interested in a personal capacity, I am also hoping to start a discussion for the many other HN members who happen to be studying around the world and equally are investigating options for the summer ahead. Ultimately any information about internships and technology experience opportunities for undergraduates is welcomed here. Thanks
