Jessica was born in San Francisco, California in the same hospital as her fellow Girls’ Generation member Tiffany.While on vacation in South Korea, she and her sister were scouted in a shopping mall by S.M. Entertainment and joined the company in 2000. She spent seven years as a trainee before debuting as part of the Korean girl group Girls’ Generation. Jessica attended Korea Kent Foreign School in her teenage years.
Her younger sister Krystal is a member of the Korean girl group f(x).
Krystal was born as Chrystal Soo Jung in San Francisco, California, where her family from South Korea settled in the 1980s. During a family trip to South Korea in early 2000, at the age of five, she and her older sister Jessica were spotted by talent agency S.M. Entertainment, which earned her a cameo appearance in Shinhwa’s “Wedding March“ music video. The agency saw potential in both Krystal and her sister and offered them singing and dancing lessons, opting to professionally train them in a singing career. However, the offer was turned down by her parents, reasoning that Krystal was too young. Therefore, her parents at first only allowed her older sister to join the agency, who debuted as a member of the girl group Girls’ Generation. Since then, the Jung sisters have appeared together in many events.
In 2002, Krystal began appearing in television commercials. She first appeared in a Lotte commercial with Korean actress Han Ga In.
In 2006, her parents finally allowed her to join S.M. Entertainment, and the agency then enrolled her in dance classes, including jazz and ballet. Krystal was trained for 3 years before debuting as a part of f(x) in 2009.
In early April, Jessica and her sister Krystal were announced to have their own reality television show.Jessica & Krystal was premiered on June 3 and consisted of ten episodes. The show featured the daily lives of the sisters.
During one interview segment, the two sisters addressed their public “cold“ image together. Jessica explained “The average person thinks of idols’ bright images, but my sister and I tend to not have strong expressions. If I’m not so lively, other people could get in a bad mood or misunderstand. I wish they wouldn’t think me as rough.“
Jessica & Krystal takes the viewers behind the scenes, to unveil Jung Soo Yeon and Jung Soo Jung’s normal, everyday life as sisters and friends. The use of the pair’s Korean names implies that the viewers will be seeing an up-close and personal side of the two sisters, instead of their stage appearance as Jessica & Krystal. CJ E&MOnStyle’s CP Kim Ji Wook stated, “The one-of-a-kind Jung sisters’ real lifestyle will be unveiled. We ask that you show a lot of interest and anticipation for the reveal of the lovely sisters’ private stories.
Jessica & Krystal, featuring Krystal and her sister, Jessica Jung, premiered on June 3 and consisted of 10 episodes. The show took on a more close-up and personal side of the two sisters, showing their affection towards one another, featuring their daily life activities, as well as never-before-seen footages.
During one interview segment, the two sisters addressed their public “cold“ image together. Jessica explained “The average person thinks of idols’ bright images, but my sister and I tend to not have strong expressions. If I’m not so lively, other people could misunderstand. I wish they wouldn’t think me as rough.“ and Krystal added “I don’t particularly want to explain. This is us, so what could we do?“ They also expressed their sisterly bond, saying “If we didn’t work in the same business, we wouldn’t be this close...we understand each other more than anyone else. If we didn’t have each other, it would have been difficult.“

Jessica是韩国籍的，Krystal是美韩双国籍的。
Tiffany是韩国籍的。
在韩国是允许艺人双重国籍的。
至于为什么Jessica是韩国籍，Krystal是双重国籍，是组合原因。
少女时代刚出道的时候是不允许艺人双重国籍的。
并且在韩国外国籍艺人会有很多限制，所以J和T国籍都改为韩国。
f（x）出道的时候，韩国允许了艺人双重国籍，并且对外国国籍艺人没有什么限制了。
所以队内宋茜是中国国籍，Amber是美国籍，Krystal是双重国籍。
