Mmmm, I think at the moment my range of potential places-I-could-work are just very, very broad, too broad to be able to do something like target all companies that do X, which is probably one of the reasons I find the suggestion a bit unnerving. Plus I quite fancy working in the public/charitable sector, where as you say things are more structured!

*sigh* I suspect I am stressing myself out about this all far too early, but at least I should have a firm idea of what I can actually say to people in terms of 'hi, here are my skills' by the time I leave the US. Which will be precisely when, according to my records, the temporary job ads spiked. Sigh.
