The woman has a job, her employer says it has been unable to find anyone else suitable and Sunita Khan "has proven to be a very competent and caring person who delivers care to the elderly with expertise and commitment.
"Sunita's empathy and enthusiasm ... exceeds that of those we currently see in the market."
In other words, because locals are too lazy and not competent enough by comparison, she is invaluable to the employer, and by implication the employer's customers (who are elderly). She works 6 days a week, as does her husband (quick tell the unions, there are people who work harder than they do and are pleased to do so).
However, immigration bureaucrats think otherwise. None of them with productive jobs themselves, they want to deport a woman and her husband who are.
So if the bureaucrats (and by implication the politicians who made the law) have their way, out they go, just so the employer can hire someone second rate who is a keewee.
