Yes, your husbands employer will pay for his health insurance (which will cover the whole family).
That is...if he can find a job where his boss is willing to pay it.
I've been reading this thread from beginning and have started to write a reply several times but have deleted it every time.
Simply because I couldn't find the right words.
I understand your reasons for wanting to go back but at the same time feel that you shouldn't underestimate life here.
You have been living here before so you know what you can expect. But...apparently you had to go back since it didn't work out financially.
Why do you think it would be different this time? Life here isn't cheap, especially with children.
Many of my friends have returned to their homecountries around the time that their children had to start school.
Simply because they weren't able to afford a private education for their kids.
If you would like your children to go (a good) university, it will cost a lot of money.
Either a private school, or the expensive dershane lessons, or bribing your way into one of the better state schools.
Another issue is the so-called "better quality of life".
That is definitely possible but only if you can afford it.
Both my husband and I have a business and at the moment we are closed on Sundays. Yes, that is costing us income but we have a 2 year old and we don't want her to grow up in such a beautiful area without ever going to the beach, walk in the forests or such with both her parents. We can afford to close but reality is that a lot of the children never get to enjoy the amazing surroundings because the parents don't have time. And if they do, it is quite often without their father since he could be working night and day in tourism without a day off.
I think that in your case, my decision to come or not would be based on the chances of your husband being able to find a good job.
Does he have a profession/education/previous experiences that will allow him to work all your round for a proper wage?
I don't know whether such a thing is possible in the UK but can't your husband get a leave of work (for example 6 months).
He would then be able to come to Turkey, find a job, look for a place to rent, etc before you and your daughters come over.
You might stay separate for a while but at least you won't be making decisions that are difficult to reverse in case it doesn't work out.
Good luck with deciding what to do!
