Actually, no non-citizen in a U.S. ice dance team got a break in reduction of the arduous and long U.S. citizenship process, especially not Christina Carreira! She would have had her citizenship a number of years ago, had she went the normal route from the beginning. Her initial immigration atty suggested she try for an Extraordinary Person visa which drastically reduces the citizenship process. But she was much younger then with a lot fewer athletic career accomplishments. And that type of visa is usually not given to athletes. It's more often for vastly accomplished scientists, notable VIPs in industry or politics, classical musicians, or well-connected celebrity entertainers. Christina certainly did not fit the requirements. Thus, she had to start the entire process over again, losing several years at least. What might have taken her 8 years, ended up being around 11 years! Plus, all the commuting back-and-forth from Canada after she and Anthony switched coaches and relocated.
In Vadym's case, he has followed the lengthy citizenship process that began when he first came to the U.S. in his youth and partnered with Avonley Nguyen -- they had a successful and exciting junior career. The citizenship process was not sped up for him as a result of his career wins, though. Vadym and Christina are just fortunate that the end of their long U.S.citizenship quests fortuitously came to successful closure last fall in time for the 2026 Olympics. Neither received any special reduced time waivers, like typically happens in other countries for figure skaters, e.g., Deanna Stellato; Laurence Fournier-Beaudry; Bruno Massot; Nikita Volodin; and Tim Dieck, et al. Albeit that Massot and Volodin had to pass the difficult German language test.
