A South African citizen who was working in Texas but says he was deported in July is seeking up to $1 million from immigration firm Foster LLP of Houston and partner Jose Perez in a legal malpractice lawsuit alleging they mishandled his permanent resident visa application.

Warren Miller alleges in the petition he filed on Sept. 8 in state district court in Harris County that as a result of the defendants’ negligence and misconduct, he lost his job in the United States and had to take a much lower-paying job in the United Kingdom. He alleges he also had to put his house in Katy on the market and is obligated to pay for a leased car.
