Your 401k is still good in other countries so unless you need it to move you might want to wait until you start work where you're going and find out what you can do about transferring it there.
That way you avoid the big chunk taken out for the tax man.
Thanks for the help, everyone.
I'm moving back to a European country, where I'm originally from. Minimum wage is close to $12 an hour, women get six months paid maternity leave, not like the crappy six weeks you get in America, and pretty much all medical expenses will be free.
