Has anyone from a non-EU country (preferably USA) moved an elder parent to CH for Memory Care?

We’re in the position of investigating options at the moment, but I’m in the situation as an only child with relatively no extended family of what to do with a parent with a recent dementia diagnosis. If we use assisted living in the US the parent would be alone and we could only visit one or two times a year. If we move parent here, they are close and not alone, but is it even possible - insurance, immigration etc… we would have the resources to financially support.

Any help greatly, greatly appreciated!
