I see families who are not entitled to NHS care bring over their loved ones and they get admitted to hospital.
Not being racist but I see mostly Indian and Muslim based ethnicities doing this.
We have a department we refer them to, which then investigates their right to NHS care and charges them if they are not eligible.
But as far as people here on spouse visas and/or such like are concerned, there should be no problem and it's just a formality as they have got hotter on the NHS staff in trying to stop these so called health tourists.
