I have to say, even though I agree it is more about immigration than terrorism, the rule still seems silly to me. Can illegal immigrants not fund short term purchases of fully refundable tickets? And in these days of e-tickets, which are hardly the most secure and fraud-free documents[:w], exactly what does a return ticket really signify. And why not just fly to, say, Mexico and walk across - you don't need to show a return ticket crossing the boarder on foot.
Not quite that easy to get in from Mexico anymore.
You now need to have a passport to get back in,as a Mexico resisdent you need to have a visa to get into the country and trust me they do take this seriously at the TJ border crossing,having spent a couple of hrs chatting to them after I forgot my green card one night/morning.
