Why the visa route may fit
The student is abroad, needs a visa for initial travel, and is prepared for the consular application and interview.
Pathway comparison
Both routes can lead to F-1 student status, but the agencies, procedures, travel consequences, and timing are different. A visa is requested through a U.S. embassy or consulate. Change of status is requested from USCIS by an eligible applicant already in the United States.

Interview preparation, temporary study purpose, finances, and travel
Current status maintenance, I-94 timing, changed circumstances, finances, school deferrals, and travel risk
The student is abroad, needs a visa for initial travel, and is prepared for the consular application and interview.
The applicant is already in the United States in an eligible classification, can maintain status, does not need near-term travel, and has a credible new academic plan.
A USCIS change-of-status approval is not an F-1 visa. After departure, a student generally needs the appropriate visa before returning in F-1 status.
