acceptable frequency of visitation and length of stay

[george2005]

Hello,

We are relocating to London, and it appears that we will not be able to bring our nanny with us under a Domestic Worker visa due to her US immigration status. However, she is very attached to our daughter, and we wanted to know whether she could visit us regularly under a visitor visa (our nanny is Argentine). If every time she came she had a return ticket, her stated purpose was to visit us (not to work for us), would there be any limit on the number of times she could visit or the length of her stays (assuming obviously that they are not longer than 6 months?)

Thanks for any help, my wife is very sad at the prospect of separating our nanny and daughter and we are trying to find a way to lessen the sadness.
