On 12 September 2024, Internacional announced that it had reached an agreement with Liga MX Femenil side Club América to transfer Priscila to América for a $497,403 usd fee plus performance-based bonuses, making this the largest transfer fee received by a Brazilian women’s football club, the most expensive acquisition by a Liga MX Femenil club, and one of the most expensive transfers in women’s football. Inter also stated that they would receive a 20 percent fee of any future transfer of Priscila from América to another club.[6][7]
Priscila made her debut with América on 26 September 2024, coming as a substitute in a week 12 league match against Santos Laguna as part of the Apertura 2024 tournament.[8] She scored her first goal with América four days later on 30 September 2024, in a week 13 league match against Club Tijuana in which she was part of the starting line-up.[9]
Priscila played in the 2024 Summer Olympics, winning the silver medal. She helped Brazil open the score in the semifinal against Spain, as she advanced on goalkeeper Cata Coll doing a goal kick, and the ball bounced on Priscila before hitting defender Irene Paredes, leading to an own goal. Priscila's taunting celebration screaming at Coll's face received great repercussion, with her later explaining that it was "a way of letting out all of the emotions that had built up over those few days”, particularly after hearing the Spanish players mocking the Brazilians on the way to the pitch.[11][12]
