Hollycat - Baroness this morning on Today programme was very emphatic that it is in everyone's interests - both EU nationals here and UK in Europe, to resolve this before the negotiations start. Because once they start everything remains un-resolved until the end of the negotiations. And even then - there could be chaos and limbo for all.
If we don't do this it will be in the pot for who knows how long.
She also made the point that if the UK does the principled thing and gives a promise now, then we are much more likely to end up in a mess.
My dentist is from Spain and his young family are settled here. Look around you - and unless you live in a very remote corner of the UK you probably know someone doing a vital job, or married to a UK national, that you would want to reassure.
And of course it would be a disaster for the NHS, the care sector and many businesses if there was an exodus of EU Labour. It's already begun. (Back to trying to get doctors and nurses from countries that can ill afford to lose them? Always an option.)
Hannah... I'm mystified unstable areas of the world ?? Are you talking about refugees?
