I was surprised to learn how competitive the nursing programs are.A healthcare qualification makes you essentially recession-proof and (especially for nurses) a recognized certification allows you to travel and work practically anywhere in the world with minimal fuss compared to non-healthcare professionals. If she wants to stay in the US she'll have plenty of job opportunities and need never be unemployed. So it's a great ticket.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
