Is it easier for Mexicans to get into Stanford University?

There's no evidence to suggest that Mexicans, or any specific nationality, have an easier time getting into Stanford University than any other. Stanford's admissions process is famously rigorous and holistic, considering a wide range of factors including academic performance, extracurricular activities, essays, letters of recommendation, and demonstrated interest. While Stanford actively seeks a diverse student body, admission is based on merit and individual qualifications, not nationality.
