Federal student loans in the United States are authorized under Title IV of the Higher Education Act as amended.

These loans are available to college and university students via funds disbursed directly to the school and are used to supplement personal and family resources, scholarships, grants, and work-study. They may be subsidized by the U.S. Government or may be unsubsidized depending on the student's financial need. The U.S. Department of Education published a booklet comparing federal loans with private loans.[5] In this same document, the government describes what you may use the loan for:

You may use the money you receive only to pay for education expenses at the school that awarded your loan. Education expenses include school charges such as tuition; room and board; fees; books; supplies; equipment; dependent childcare expenses; transportation; and rental or purchase of a personal computer.

Both subsidized and unsubsidized loans are guaranteed by the U.S. Department of Education either directly or through guaranty agencies. Nearly all students are eligible to receive federal loans (regardless of credit score or other financial issues). Both types offer a grace period of six months, which means that no payments are due until six months after graduation or after the borrower becomes a less-than-half-time student without graduating. Both types have a fairly modest annual limit. The dependent undergraduate limit effective for loans disbursed on or after July 1, 2008 is as follows (combined subsidized and unsubsidized limits): $5,500 per year for freshman undergraduate students, $6,500 for sophomore undergraduates, and $7,500 per year for junior and senior undergraduate students, as well as students enrolled in teacher certification or preparatory coursework for graduate programs. For independent undergraduates, the limits (combined subsidized and unsubsidized) effective for loans disbursed on or after July 1, 2008 are higher: $9,500 per year for freshman undergraduate students, $10,500 for sophomore undergraduates, and $12,500 per year for junior and senior undergraduate students, as well as students enrolled in teacher certification or preparatory coursework for graduate programs. Subsidized federal student loans are only offered to students with a demonstrated financial need. Financial need may vary from school to school. For these loans, the federal government makes interest payments while the student is in college. For example, those who borrow $10,000 during college will owe $10,000 upon graduation.
