TLC announced the couple's Season 7 debut in an extended preview at the end of Sunday night's 90 Day Fiance episode as well as an additional promo that aired during a commercial break of the night's subsequent Pillow Talk broadcast.
In the brief promo that aired during Pillow Talk, an on-screen graphic read, "Look who's back next Sunday," with footage of Angela.
Angela tells the cameras in the clip, "We applied for the K-1 visa and Mike could be here within a month. What a party we're going to have!"
The Georgia native and Michael from Nigeria were also shown kissing.
At the end of 90 Day Fiance's Season 7 episode on Sunday, Angela was shown FaceTiming Michael on her phone.
"I'm sweating to death worrying about this visa now," Angela admits.
"Don't worry. I got this," Michael replies.
"You know the consequences if you screw up," Angela says, before telling the cameras in a confessional, "It's either the K-1 or K-done."
However, Angela and Michael had not appeared in Season 7's first five episodes.
Additional footage of 90 Day Fiance's sixth Season 7 episode was teased in both promo videos.
Anna Campisi's two eldest sons were shown saying they didn't want their mother and Mursel Mistanoglu to go through with their wedding, and Sasha Larin cried at the airport in Russia as he said goodbye to his parents in order to move to America.
Syngin Colchester was also shown tearing up as he said goodbye to Tania Maduro, who was heading to Costa Rica for one month to learn herbalism. Although Syngin had just arrived in America, he was being forced to spend a month alone.
"Syngin definitely is the clingiest man I've ever met in my life," Tania tells the cameras.
In addition, Blake Abelard was shown revealing he and Jasmin Lahtinen must spend their 90 days apart because his "old school" parents won't allow them to live together under their roof.
"I didn't move here [to America] to be in a long-distance relationship," Jasmin vents.
And Michael Jessen apparently brings up the idea of a prenuptial agreement to fiancee Juliana Custodio de Sousa, before his ex-wife Sarah Jessen admits, "I hope I didn't stir the pot in any way."
Angela, a 54-year-old from Hazlehurst, GA, and Michael, a 30-year-old from Lagos, Nigeria, just appeared on the third season of 90 Day Fiance: Before the 90 Days that finished airing on TLC in October.
Their story ended on the Tell-All special with Angela revealing she and Michael were still together and in the midst of the K-1 visa application process that would allow Angela to bring Michael to America and give the couple 90 days to get married.
Michael was preparing for his K-1 visa interview at the time and Angela was saving up money for Michael's arrival into the United States. During the Tell-All -- which was filmed this past summer -- Angela told the cameras Michael would probably be moving to America by the end of 2019.
Angela and Michael, whose formal name is Kehinde Ilesanmi, initially starred on Season 2 of 90 Day Fiance: Before the 90 Days before also appearing on Season 3 of the TLC spinoff.
Angela, a divorced grandmother of six children, met Michael for the first time on Facebook. The pair talked on the phone for several months until Angela decided to travel to Nigeria in order to meet Michael in person.
Despite having received warnings from friends that Michael might be scamming her, Angela intended to propose marriage right away.
But once the pair got to know each other better in Nigeria, Angela discovered some red flags, and so she realized she needed more time to get to know Michael and his intentions.
Angela's trust issues in her relationship with Michael worsened as time went on because she accused him of lying over and over again. The couple fought constantly and broke up but reconciled multiple times.
The main problem for Angela and Michael, however, is that Michael wants to have a baby so his family name will continue on. Given Angela's age, there isn't much hope she can carry a baby herself.
"I would be lying if I tell her I can be happy without a child," Michael confessed to cameras during the third season of 90 Day Fiance: Before the 90 Days.
