U.S. student IDs are generally not recognized for discounts in Cuba, as most student discounts are reserved for Cuban citizens or students at Cuban institutions. However, it’s worth asking at museums or tourist sites, though discounts for foreign students are rare. The best option for U.S. students is to carry an International Student Identity Card (ISIC), which is more widely accepted and may help secure discounts on entry fees, transportation, or accommodations, though it’s not guaranteed.
