Long-distance relationships have challenges that are sometimes difficult to overcome but consider if the distance traveled was halfway around the world and a couple had just 90 days to decide whether the courtship should conclude with marriage. That's the situation facing the men and women profiled in this series, which includes bonus footage not seen in episodes of "90 Day Fiancé." Using a visa that allows foreign sweethearts of American citizens to travel to the U.S., the men and women experience life in the States with their prospective mates for the first time. Culture and language barriers must be overcome -- not to mention the stigma of being thought of as mail-order spouses -- but here's the elephant in the room: The couples must marry before the visas expire in 90 days, or else the visitors have to immediately return to their countries. With the clock ticking, these couples discover if their "happily ever after" is meant to be.
