I'd encourage everyone to consider the BUNAC work abroad program. I have only lived in a college town in Oklahoma and a large city in the UK, but I found that the opportunities for high-paying temp work even for someone without a degree were fairly good. At the time I went, I was in the middle of my degree and made 6 pounds an hour (about $11), which was the highest paying job and only full time job I've had.
I did think I was treated fairly badly and looked down upon for attempting to work efficiently instead of spending most of my day socializing (the company was in the midst of layoffs and had about 2x as many employees as it needed-- I wrote my PS on this actually), but the experience was really worth it.
I would never work for that company again, but I may go back to the UK this summer and do temp work. I really have no idea what I am going to do, but part of it depends on where I am going to law school next year and whether I think I need to stick around the US in order to deal with arranging loans and such.
Does anyone have any advice on how getting into a top law school could affect my summer employment prospects? Any anectdotal success stories?
