I’m the one who does all the au pair searching but my DH keeps worrying about whether we are on dodgy legal ground if our au pair isn’t taking English lessons (only one ours so far has wanted or needed to) or not eating every meal with the family (again, thus far all of ours have been quite independent and off doing their own thing when not on duty) because then he says they don’t really count as an AP for visa purposes. My view is it’s not like someone is knocking on doors checking on these things and as long as we are treating them well and as they expect then I don’t see any problems arising from not matching every criteria.
