"90 Day Fiance" offers a unique look into the world of international dating and matrimony.

Using a unique 90-day fiance visa, the K-1 visa, four women and two men will travel to the U.S. to live with their overseas partners for the first time. The couples must marry before their visas expire in 90 days, or the visiting partner will have to return home. They'll have to overcome language barriers, culture shock and skeptical friends and family -- all with a clock that starts ticking the moment they step foot on U.S. soil.

The stakes are incredibly high as these couples are forced to make a life-altering decision: get married or send their international mate home.
