Dude, I've resolved for myself that step one is to get everyone a passport, and stash some money outside the country (not an easy task). I'm pretty sure nothing is going to happen and this is just some scare-mongering, but it pays to be prepared and you lose nothing otherwise. Waiting for one birth certificate, that should be here by month end. Passports apparently take about two weeks. Cutting it a bit fine if these prophets are right, though I am confident that they are not.
Technically one should always have a valid passport, that's just common sense. So much more dignified than sneaking over the border on foot.
