Came over to the UK and BUNAC sponsored the program. I discovered towards the end of my (really awful) internship that the company I was at had lied to the program and as a result also likely violated the conditions under which BUNAC can give out there Visas. I did send an email to them about this (and to there partner, The Intern Group, who were the ones who found the job), and nothing was done. It seems they do not care. I also was told that visa's couldn't be extended, which according to the UK governments website is a bald faced lie. The website is outdated, and I had to email all the documents for my application in as it refused to work for me. Don't trust these guys, they're not well run.
