The series has spawned over twenty spin-offs, including 90 Day Fiancé: Happily Ever After, which tracks past couples after their marriages; 90 Day Fiancé: Before the 90 Days, which features couples who met online but have not yet begun the K-1 visa process; and 90 Day Fiancé: The Other Way, where the American partner relocates to their partner's home country. Collectively, the original series and its spin-offs are referred to by TLC's parent company Warner Bros. Discovery as the "90 Day Fiancé Universe" or simply the "90 Day Universe". The show is centered around the K-1 visa process, which allows a fiancé from another country to travel to the US to live with their prospective American spouse. The K-1 visa is designed to provide time for the couple to arrange their marriage ceremony. As part of the visa process, each couple is required to sign documents affirming their intent to marry. If the couple does not marry within 90 days of entering the US, the foreign fiancé must leave the country.
