Btw, as I've been thinking about this, what do people do if they have ticket with a return 120 days later? Do people get denied boarding unless they can prove a) they will be somewhere else for 30 days or b) will be picking up a visa once they are in country? I know that this is the whole point of these checks but I would imagine there are all kinds of legitimate situations (including MRs) where folks would run into these limits.
