Mother Visit Visa

My mother applied for family visit visa from NEW York and she was granted 1 year multiple visa. but under remarks it says C-Family Visit and Duration of stay 180 days.

Does it means she can not live more than 180 days in the year?

Please advise

Thanks.

Well, she shouldn't be 'living' in the UK on a visitor visa because then she is not a 'genuine visitor'

But to answer your question, she cannot be seen to be spending more time in the UK that in her country of residence and the general rule is no more than 6 months out of 12.
