Everyone in UAE has access to health care. There are private hospitals for those with private health care, and there are government hospitals for those without. The health care in the government hospitals is very good (I had my first child in a Gulf Country Government hospital as that was all that was on offer - it was excellent).
While I understand people expressing concerns re human rights in UAE, to call it a shithole is just wrong. Yes, women are safe, we never locked out doors or windows and could happily leave out cars unlocked too. One of our cars has keyless entry and starting - and by mistake we left it running in a mall car park, two hours later we returned to the car still being there. It is that safe.
My children are far from racist, how can they be when their friends come from India, Pakistan, the Gulf, Europe, the Antipodese ? My husband's boss is from Sri Lanka, his colleagues are Saudi, Lebanese, Qatari. Not everyone in the Gulf lives in a little Britain atmosphere - although it may seem that way if you have only holiday'd there as the hotels and malls are just a snapshot of life out there. It is a true melting pot of nationalities living together.
With regards to doing a runner because you owe money - this is no-one's fault but the borrowers. The problem is that many newbies to the Gulf want what they see everyone else has got - a car each, large expensive house and so on. For many people who have that type of the lifestyle they have lived there for many years and worked up to that standard or living. When we arrived in UAE we drove a clapped out Daewoo Racer, but ended up with three cars, all owned outright. The majority of people handle their money sensibly and don't have to do a runner due to wracking up credit.
The problem with women being sent to jail actually says more about the husband's than the local law. I have a very dear friend who ended up in jail because her husband is a complete arsehole who used sharia (ie. not his 'own' British) law against her. if he had not reported her she would not have gone to jail as the authorities tend to turn a blind eye to adultery amongst the ex-pats (if they didn't they might not have room for other 'criminals' in their prisons).
UAE and the Gulf certainly aren't perfect, but they are pretty awesome. There are huge benefits to living there, and disadvantages too. My kids aren't as close to extended family as they might be if they'd been brought up 'at home', they don't have roots, their best friends lives hundreds, and in some cases, thousands of miles away. Returning to UK can be difficult, as an ex-pat our points of reference are different, things change while you are away which can be a bit of a shock! But if I could go back I would do it all over again.
It is a difficult age to move, especially if it is just for a year. But exams nowadays are so standardised that you could, theoretically, move during GCSE years. My DD did and did fine - got A's and B's as predicted, she finished year 10 in one country and started year 11 in another. Not for everyone and I am sure I will get slated on here for it, but she did it and all has worked out fine.
A hard decision maartje - and best to look at expatwoman.com for advise - although it can get a bit stormy over there too! Good luck.
