Just days prior of the Olympic entry deadline, Seniuk and two other athletes were faced with passport issues. This occurred since Seniuk was not a permanent resident in Israel, preventing the Israeli Olympic Committee from naming her to the team. "The Times of Israel" shared that "after a regulation passed in 2023 mandated that immigrants can receive a full passport only after a year of residency during which they prove that the centre of their life is in Israel." Only the interior minister has the overall authority to grant passports for those who do not meet the qualifications of this law. However, there had been no interior minister since October 2025 after Yariv Levin<nowiki/>s' temporary post had concluded. One day before the Olympic entries deadline, on the 25th of January 2026, Seniuk was officially named to the Olympic team. Additionally, she was named the flag bearer for the Olympic Opening Ceremony.
Seniuk made her Olympic debut at the 2026 Olympic Winter Games. She placed 22nd in the short program. In the free skate, she struggled on multiple jumping passes; she finished 24th overall.
On the 18th of March 2026, one week before the competition, Mariia withdrew from the 2026 World Championships.
