Thank you for the replies!
Rblondiebelle, my husband is a Brit, so at least he doesn't have visa worries and knows how the system works. Problem is, he doesn't know what he wants to do job-wise, but knows he doesn't want a desk job. So agencies might not be the best match, but then a few temp jobs in the interim might not be a bad idea either. Volunteering also a good thought, will suggest he explore that one.
Sonofasailor, the only thing I know about that book is that a former friend/roommate read it partway through and threw it at the wall in frustration; or disgust, I was never sure. Will explore it a bit more.
