Rachel Corsie is a captain for Kansas City.
The deal for the centre-back is Villa's third of the window.
It follows moves to take both England and Manchester City players on loan from the same team.
After moving to the United States in March of last year, Corsie played the early part of the last season on a loan at Villa's local rivals.
She signed a two-and-a-half year deal at Villa and the move is subject to international clearance.
When we heard of her availability during the transfer window, we simply couldn't ignore her leadership and overall quality.
She will guide our young talent and give us another aspect at the back. We are delighted to add her to the squad.
Villa are in ninth place in the Women's Super League and broke a run of four consecutive league defeats with a last-minute win atLeicester on Sunday.
