This is an immigration malpractice case where the lawyers were hired to represent a woman to help her obtain a green card. They apparently succeeded in that effort. Later, the plaintiff was deported. She sued the lawyers for legal malpractice, arguing that they failed to prevent the deportation.
The defendant lawyers argued that the representation ended when the green card was issued. Therefore, under their logic, they did not commit legal malpractice by failing to prevent the deportation of the plaintiff.
