She started her career as a model but quickly decided to pursue her dream of becoming an actress. Her career in Poland was gaining momentum. TV viewers might remember her from roles in "Samym życiu" and "BrzydUla." She also co-hosted the national Eurovision pre-selection and the New Year's Eve Power of Hits 2007/2008. She was at the peak of her popularity but decided to take a big risk. She made the decision to fly to the United States.
Katarzyna Sowińska wanted to complete her acting studies at the Warsaw Theatre Academy, but her age was a barrier. So, in 2010, she decided to try her luck in Los Angeles, where there are no age restrictions for students. "I made a quick decision. I sold my apartment, my car, took my savings, and left," she said in an interview.
Everything was going according to plan. Katarzyna Sowińska completed her studies at the Howard Fine Acting Studio and later at the Margie Haber Studio. She planned to spend two years overseas, and just when she was about to return to Poland, she met Luis Miguel, a Latin singer, and started touring with him. They performed in several states across the USA, in Argentina, Colombia, and Venezuela. However, Sowińska did not give up on her acting career. She attended auditions but with little success.
I made it to the final stage of casting for the TV productions 'Spartacus' and 'NCIS,' I participated in screen tests for one of the James Bond films and for a role in the series 'Luck,' which was ultimately played by Weronika Rosati"
- she admitted. Eventually, she decided it was time to return home.
She spent six years in the United States, and although she could have pursued a musical career, she wanted to establish herself as an actress. After returning to Poland, she had to find her place again, but she quickly landed a role in "Pierwsza miłość" and a position at the Komedia Theatre. "I feel like I’m just at the beginning of my professional journey in Poland" - she said after returning. Today, Katarzyna Sowińska guards her privacy. It is known that besides acting in TV series, she is also involved in recording audiobooks.
