Mamguliz I don't know if the US is as strict as Canada regarding immigration, but I would imagine it is probably more strict.
My friend - a homeowner - emigrated to Canada ten years ago when she was about 78 to be near one son living there and one son living in the US (both are chartered accountants so have good salaries). It took her about three years to jump through all the hoops for permission to live there, and she had to provide a great deal of information as to how much capital and income she had. I believe her sons also had to act as guarantors should she run out of money.
I can understand why you would want to move to be near your son and grandchildren and I suppose if it were me I would feel similarly drawn. The US would not be a country I would ideally choose because of its awful health system and gun culture but I can certainly understand the pull of wanting to be near your family.
I think the idea of visiting for several months of the year is quite a good one but I suppose you have to bear in mind that you might not always be able to do that. It is said that travel insurance is going to be very much more expensive from now on.
I wish you good luck and happiness, whatever you decide.
What words annoy you when used wrong or people don't know the meaning of?
People being over fussy about cat welfare
Anyone else struggle with this?
Support and friendship for those whose lives have been affected by estrangement.


. Whilst we were over there, we travelled widely including to LA. I liked the States but I’m not sure I would want to live there. My biggest issue (as other’s have said) would be healthcare particularly as you are both in your 70s – you say you are both fit and healthy but as you get older you are going to need health care – that is a given - and when I say that I also mean social care – support at home etc everything in the US is paid for personally or more likely by insurance and health insurance won’t cover everything and you will find, because of your ages, your premiums will be real high. Also, in the US you need a car, no question. I think as other have said it would be something to try first for an extended period of time to see what it is like rather than burn your bridges.
