Is TLC's 90 Day Fiancé fake? That's what fans are wondering ahead of the Season 2 premiere of the spinoff 90 Day Fiancé: Happily Ever After, since it's rumored that many of the couples from the show have since split. But franchise star Anfisa Arkhipchenko — who appears to still be together with her husband Jorge Nava — took to Instagram to clarify what intentions the couples have when signing up for the show.

"I see a lot of people saying '90 days is not enough to get married,' '90 days is not enough to get to know somebody,' or asking 'Did you guys date before getting married?'" she wrote in the caption of a screengrab from tonight's season premiere. "What they don't understand is how the show actually works."

She explains that the show does not match people from other countries with singles in the United States and then begin filming their relationships. Instead, the show finds its subjects through an application process. The show features couples who have already started or are hoping to begin the process of applying for the K-1 Fiancé Visa, which means the couples have already been involved in long distance relationships with their significant others and have already met in person at least once, since it is a requirement in order to apply for the Visa.

"The show doesn't help with anything related to immigration," the 21-year-old wrote in her caption. "They just start filming on the day foreign fiancé(e) arrives to the USA and continue until the couple gets married."

She also explained that while the Visa allows the couples to spend 90 days together before they tie the knot, it's not a requirement to wait the whole 90 days but it is a rule that they must get married before 90 days has passed.

"This '90 days' are definitely not to get to know your partner because you already know the person you've had long enough relationship with and decided you want to marry them," the aspiring model continued. "That's why all of the couples end up married every season."
