Which character becomes House’s wife in House M.D.?

Dominika Petrova becomes House’s wife in House M.D. as part of an arrangement involving her immigration status.

Dominika is a Ukrainian immigrant who enters House’s life during the show’s later seasons. House agrees to marry her so she can obtain a green card, making the relationship initially a practical arrangement rather than a conventional romance. Their connection develops while they live together and learn more about each other.

The marriage is legally significant in the story, but House and Dominika do not become a traditional long-term couple. Her storyline explores House’s guarded emotions and his tendency to approach personal relationships through schemes and calculated bargains.

Dominika is sometimes confused with House’s former partner Stacy Warner or with Lisa Cuddy, his hospital superior and romantic interest. Neither Stacy nor Cuddy becomes House’s wife; Dominika is the character connected to the marriage plot.
