In financial terms, studying in the USA is much more expensive than in Europe. Each university establishes its own tuition fee, with the average ranging between $15,000 and $30,000 per year. Food and accommodation cost an additional $15,000 per year. Add also health insurance. In practice, many universities offer scholarships and social support to cover the expenses; you can find the information on each university’s website. Besides, many Polish and international foundations offer grants for studying in the USA; examples of such grants can be found here: http://pso-usa.org/studia-w-usa/informator/stypendia/.
