Can outstanding students apply for a UAE golden visa and what is required?

Yes, outstanding secondary-school students can be considered for a UAE golden visa, typically a five-year permit. The published route for high-school students rests on top academic performance, with a very high minimum grade in the final certified results, combined with identification through the education authorities rather than grades alone; in practice the Ministry of Education and emirate-level education bodies identify qualifying students, and the family then completes the application through the federal ICP or the relevant residency authority with the certificates and identity documents. So both things you mention matter: the grades make her eligible in principle, and the official listing or nomination is the mechanism that unlocks the application. University students can also qualify later through a separate strand based on attending well-ranked universities with a strong academic record, which is worth knowing if the school route does not land this cycle. On timing, the application follows the final certified results, so the window opens once her grades are formally issued; ask her school now whether it submits nominations and what the current cycle requires, since the criteria are reviewed between years. An immigration specialist or licensed UAE lawyer can confirm the current requirements before results day.
