Choi was a special representative forUNICEF Korea from 2015 to 2019, before being chosen as aUNICEF East Asia and Pacific Regional Office ambassador in November 2019.[3]
Choi was scouted by a talent agent fromSM Entertainment when he was 16 as he was waiting for friends in front of his high school. The agent recommended him to audition for the company'sStarlight Casting System. He auditioned without his parents' approval; his parents were notified only after he passed the auditions.[8] Although his parents allowed him to sign a contract with SM Entertainment, they did not give him any help because they wanted him to take responsibility for his actions.[9]
He later moved into dormitories with fellow trainees and was trained in areas of singing, acting, dancing as well as languages. He was featured in a music video ofThe Grace'sDana whilst he was being trained as a solo singer in 2003.[10] A year after, Choi made a brief appearance in family dramaPrecious Family,[11] and again in 2005 in the KBS romance comedy dramaEighteen, Twenty-Nine as young Kang Bong-man,[12] while in 2006 he played the supporting role of Park Sang-woo in romance melodramaSpring Waltz.[13]
Not long after Choi's first television appearance, SM Entertainment released an announcement that he would debut as one of the twelve members in a boy band.

In March 2006, SM Entertainment began to recruit new members for the next Super Junior generation. However, plans changed and the company declared a halt in forming future Super Junior generations. Following the addition of thirteenth memberKyuhyun, the group dropped the suffix "05" and became officially credited as Super Junior. The re-polished group's first CD single "U" was released on June 7, 2006, which was their most successful single until the release of "Sorry, Sorry" in March 2009, which helped them achieve global success.
In April 2008, Choi was put into seven-member sub-groupSuper Junior-M, aMandopop subgroup ofSuper Junior for the Chinese music industry. They debuted in China at the 8th Annual Music Chart Awards, simultaneously with the release of their first music video, "U" on April 8, 2008.

In 2013, Choi, along withPsy, became the first K-pop stars to attend theMet Gala.[58] In October 2015, he became the first Korean to reach 5 million Twitter followers.[59][60] In 2016, Choi was listed inForbes magazine's "30 Under 30 Asia."

In 2007, when being asked about male actors portraying sexually ambiguous roles as inThe King and the Clown (2005), Choi said: "I will respectfully refuse any such offers. While I respect all genders, I do not wish to acknowledge homosexuals as I have been taught that God created Man and Woman with specific characteristics and duties. I realize that with globalization, there are many [entertainers] who do not share my views. There are those who are value-oriented and those who are success-oriented. However shouldn't an actor deliver an image to his audience through roles he chooses to portray, based on his beliefs in life?"[69][70]
On September 11, 2015, Choi retweeted theologianJohn Piper who stated "Obergefell is not constitutional; so-called same-sex marriage does not exist." Choi also shared Piper's link to an article in support ofKim Davis, as well as two Biblical passages, confirming he remained against gay marriage. The next day he removed the retweets and posted an apology in both Korean and English. The English version went, "I apologize for my inconsiderate choice to retweet Rev. Piper's tweet. Reason I echoed Rev. Piper's thoughts was because I wished to voice a plurality of opinions. However, now I realize that my comments were hurtful to those whom I hold dearest: my fans, and their friends and families. I am truly sorry. My judgment was insensitive, thoughtless, and ill-conceived. I will do my best to learn from my mistakes and reflect on my faith. I thank everyone for their support and understanding." He later deleted the apology.[71][72]
In April 2023, Choi has been accused of transphobia over a meme he posted on Bubble, a private online discussion platform. The controversial meme shows a scene from the movieTitanic (1997) in which actorBilly Zane's character Caledon Hockley is trying to be rescued but is told "women and children first." Zane's character then claims: "I'm trans." Choi wrote "It's funny kekekekeke" along with the image.[73][74][75]
On September 30, 2017, an untied French bulldog owned by Choi's family bit their neighbor, 53-year-old businesswoman Kim who ran Hanilkwan, an upscale Korean cuisine restaurant. This resulted in the death of the victim six days after the incident. The cause was identified assepsis, brought on by the bite. Choi and his father separately wrote letters of apology on their Instagram accounts on October 21, 2017.[76] Although a family member of the deceased told media that the family were not willing to take any legal action, the Choi family received severe backlash from the public for not taking any precautionary measures with their dog.[77]
On September 11, 2025, following the death of U.S. political influencer andTrump allyCharlie Kirk, Choi posted an image on Instagram with the caption "REST IN PEACE CHARLIE KIRK, Charlie Kirk, rest in peace." The photo featured Kirk’s face alongside a cross illustration and was set to the song "Rescue" by American CCM artistLauren Daigle. Choi also shared a second photo of Kirk with his family, accompanied by the Bible verse "Well done, good and faithful servant." Both posts were deleted after drawing criticism from K-pop fans, most of whom cited Kirk’s far-right positions, including his support for gun rights, opposition to abortion, and remarks described as racist and anti-LGBT.[78][79]
On September 12, 2025, Choi addressed the controversy on the fan platform Bubble. He wrote that there had been "much discussion" about his post and that he wished to explain his intentions. He described Kirk as "a Christian, a father, and a husband." He added that "regardless of the circumstances, the fact that he lost his life in a shooting while giving a lecture in front of countless college students is a heartbreaking tragedy beyond any political stance. That is why I paid tribute to him." Choi said he deleted the posts after feeling that his "intentions were misunderstood." He explained that he believed his "sincere feelings had already been conveyed.[80]
