asp.net mvc - MVC Form Required base on select

Question

I have a MVC form that has a required option for the City control but in JQuery I have it hide/show base on the Country dropdown. So if the Country is US the City control will display and the user will need to enter the city. The problem I am running into is that the form will only post if the city is enter. Is there around this?

[Required]
public string City { get; set; }
