Most Indian applicants prepare for 2-4 months; expect to book exam 6-8 weeks in advance during peak seasons (July-September). Registration at www.ets.org/toefl.
• IELTS (International English Language System): Minimum overall band 7.5 with each component (Reading, Listening, Speaking, Writing) at minimum 6.5. IELTS is offered monthly in India; some students find the speaking component (live interview with examiner) less artificial than TOEFL. Registration at www.ielts.org.
• Duolingo English Test: Minimum score 110 (out of 160). This is the fastest and cheapest option; many Indian students take it within weeks. Score released within 48 hours. Registration at englishtest.duolingo.com.
• Indian Applicant Note: TOEFL and IELTS are most widely recognized and recommended. Duolingo is acceptable but some universities still prefer traditional tests for scholarship consideration. Plan 4-6 months for TOEFL prep if you are starting from a baseline (typical for non-English-medium schooling backgrounds).

Tip for Indian Students: TOEFL 100 and IELTS 7.5 are both achievable with 3-4 months focused study if you completed English coursework in Indian schools. Many applicants take the test twice; book your first attempt 6-8 months before your target application deadline to allow retakes if needed.

University of Illinois Bachelor of Science Mathematics and Computer Science Application 2026

UIUC uses the Common Application for freshman admissions. Deadlines are listed below for the next three intake cycles; application reopens each year on September 1.

• Early Action applicants receive admission decisions by January 30, 2026 (Fall 2026) or ~January 30, 2027 (Fall 2027). Admission is binding for some universities; UIUC’s Early Action is non-binding, so you can apply to other schools and compare offers.
• Regular Decision deadlines offer more time to prepare documents (transcripts, test scores, essays) and are recommended for first-time test-takers or international credential evaluation (WES, NACES).

United States Visa and Post-Study Work Pathway 2026

International students in the Mathematics and Computer Science programme are sponsored for an F-1 Student Visa, which allows full-time study and limited on-campus work. Upon graduation, eligible graduates transition to Optional Practical Training (OPT) or skilled-worker sponsorship (H-1B).

• F-1 Student Visa Duration: Valid for the duration of your academic program plus a 60-day grace period after graduation. You must maintain enrolled status and report to International Student and Scholar Services (ISSS) each semester.
• Optional Practical Training (OPT): All Mathematics and Computer Science graduates are eligible for standard OPT (12 months) and STEM extension OPT (additional 24 months, total 36 months). STEM OPT allows you to work full-time for any employer on an E-Verify system; you apply within 90 days of your graduation date through your designated school official (DSO) at ISSS.
• H-1B Skilled Worker Visa: After OPT or directly from F-1, employers can sponsor you for an H-1B visa, which is a multi-year work permit tied to your employer. Mathematics and Computer Science graduates meet the salary threshold (US$60,000-US$104,000 minimum, depending on role); most employers offer well above this range. H-1B visa processing takes 4-6 months and requires employer sponsorship.
• Permanent Residency (Green Card) Path: H-1B visa holders are eligible to apply for permanent residency (Green Card) through employment sponsorship. Timeline is typically 5-10 years depending on country priority (Indian nationals face longer waits due to visa number caps); processing is often concurrent with H-1B renewal.

Visa Reality: STEM OPT extension is a major advantage for Mathematics and Computer Science graduates; 36 months of post-study work allows you to build significant US experience and immigration documentation before H-1B sponsorship. Indian students frequently use this period to gain seniority, relocate internally within tech companies, or secure employer-sponsored immigration pathways.
