Overview: Studying in the USA
The United States is home to the largest number of world‑ranked universities and offers unmatched academic diversity. Its higher education system includes public state universities, private research universities, liberal arts colleges, and community colleges. This page focuses on 4‑year degree‑granting universities relevant to international students seeking bachelor’s, master’s, and doctoral degrees.
Because the US uses a 4.0 GPA scale while many countries use percentage or CGPA systems, understanding how your grades convert is essential before applying. This guide covers university rankings, GPA conversion, tuition, deadlines, scholarships, and visa/work rules for international applicants.
How Many Universities Are in the USA?
According to the National Center for Education Statistics (NCES) IPEDS 2025–26 collection, the United States has 3,798 degree‑granting institutions. When including all Title IV postsecondary institutions (including non‑degree‑granting), the total rises to approximately 5,600 institutions.

US Grading System & GPA Conversion
The standard US grading scale is the 4.0 GPA. Most universities convert international grades using this scale or their own internal evaluation. The table below shows the typical letter grade to percentage and GPA mapping.
| Letter Grade | GPA Points | Percentage Range (typical) |
|---|---|---|
| A | 4.0 | 90–100% |
| A− | 3.7 | 87–89% |
| B+ | 3.3 | 83–86% |
| B | 3.0 | 80–82% |
| B− | 2.7 | 77–79% |
| C+ | 2.3 | 73–76% |
| C | 2.0 | 70–72% |
| C− | 1.7 | 67–69% |
| D | 1.0 | 60–66% |
| F | 0.0 | Below 60% |
Some universities assign A+ = 4.3 for exceptional work. For international transcripts, universities may use a credential evaluation service like WES or their own internal conversion. Visit our U.S. GPA page for a complete explanation.
Tuition Fees for International Students
For the 2026–2027 academic year, undergraduate tuition for international students averages approximately $33,000 per year at public universities and $47,000 per year at private universities. Ivy League and elite private institutions typically exceed $65,000 per year for tuition alone, with total cost of attendance often above $85,000 including housing, meals, and fees.
| Institution Type | Average Annual Tuition (USD) | Typical Range |
|---|---|---|

⚠️ Important: Tuition is only part of the cost. You must also budget for housing, meals, health insurance, books, and personal expenses. International students at public universities usually pay out‑of‑state tuition, which is significantly higher than in‑state rates.

Most US universities require proof of English proficiency for international students. Common minimum scores are shown below.

| Duolingo English Test | 105–125 |
| PTE Academic | 53–65 |
No IELTS pathways: Some universities waive English proficiency if you completed previous education in English (e.g., 3+ years in an English‑medium school). Alternative tests like Duolingo, TOEFL, and PTE are widely accepted. Conditional admission with English language programs is also available at some institutions.
