Kalani, raised Mormon and always taught to save herself before marriage, lost her virginity to Asuelu and got pregnant with his baby.

Eric, 40 (Wisconsin) and Leida, 29 (Indonesia)

Divorced with three daughters, Eric met Leida after posting a personal ad on an international website. The two immediately clicked and spent much of their time video chatting until Eric was able to travel to meet Leida in Indonesia. After just two days, Eric proposed to Leida and now they are gearing up for her move to the U.S. Eric hopes that Leida and her son will help create a happy blended family along with his kids. But the age difference between them has Eric's children concerned about Leida's true intentions. In addition, Eric is fully aware that the life of luxury Leida is used to might make it challenging to adapt to his middle-class lifestyle.

Jonathan, 32 (North Carolina) and Fernanda, 19 (Mexico)

Jonathan and Fernanda met at a club in Mexico, leading Jonathan to extend his trip for an extra three days. He hadn't expected to meet someone during his trip, so he shocked everyone, including himself, when he proposed after just three months. Jonathan has made the most of his bachelor lifestyle and must prepare for the big adjustment of sharing his life with someone else. Fernanda jokes that Jonathan is robbing her of her youth by tying her down at such a young age, but Jonathan sometimes wonders if their 12-year age difference could be the demise of their relationship.

Ashley, 31 (Pennsylvania) and Jay, 20 (Jamaica)

Ashley met Jay when she went to Jamaica for her friend's wedding. While out with her girlfriends the two met at a club. Ashley didn't expect to talk to him again, but Jay tracked her down on social media. Six months later, Ashley went back to visit, and after spending just eight days together, Jay proposed. Ashley has had two failed engagements, so she's hoping the third time is a charm--but with Jay being so young and having had a wild lifestyle, she's hoping he can be serious about their relationship so that she'll finally be able to stop searching for long lasting love.

Colt, 33 (Nevada) and Larissa, 31 (Brazil)

Colt wasn't having any luck with American women, so he decided to look elsewhere and met Larissa via social media. Colt and Larissa both traveled to meet up in Mexico, and Colt proposed after just five days. Colt is a mama's boy and is used to his mom taking care of him and everything he needs, so they both must make adjustments to fit Larissa into their everyday life. Colt worries that Larissa has the wrong impression of what it means to be American after all of her high-priced demands, while Colt's family worries that Larissa is just using Colt for a ticket into the U.S.

Steven, 20 (Maryland) and Olga, 20 (Russia)

When Steven and Olga met on the beach, Olga was only in the U.S. for the summer and the two of them were just having fun.
