First-time international applicants face a wall of acronyms and jargon. This reference guide demystifies the most important terms you will encounter throughout the DS admissions and immigration journey.
- GRE
- Graduate Record Examination. Required by most US MS DS programs. Scoring range is 130–170 per section. Target 165+ in the Quantitative section for CMU, Stanford, and MIT. Strong Analytical Writing (4.0+) also matters for research-focused programs.
- GMAT
- Graduate Management Admission Test. Required for business-oriented DS programs such as Bocconi DS and Analytics, and HEC Paris. Score range is 200–800. Target 680+ for top European programs offering DS specialisations.
- F-1 Visa (USA)
- US student visa for full-time degree programs. Permits 20 hrs/week of on-campus work during term. Issued with an I-20 form from the university. Serves as the basis for OPT and STEM OPT post-graduation work authorisation.
- OPT — Optional Practical Training (USA)
- Post-graduation US work authorisation. Standard duration is 12 months. Extended to 36 months under STEM OPT for qualifying programs. Data Science MS programs are almost universally STEM-designated, making the 36-month extension standard for Indian graduates.
- STEM OPT Extension (USA)
- US extension giving DS graduates 36 months total post-graduation work authorisation. The employer must be registered in E-Verify. This is the critical bridge between graduating and securing H-1B sponsorship. Apply no later than 90 days before standard OPT expires.
- H-1B Visa (USA)
- US specialty occupation work visa with an annual lottery cap of 85,000. Success rate is approximately 15–20% per year for Indian applicants. The primary risk for long-term US residency after STEM OPT. Many Indian DS graduates face two to three lottery cycles before receiving selection.
- CPT — Curricular Practical Training (USA)
- Allows F-1 students to work off-campus for a company as part of their curriculum, typically for internships. Must be authorised by the Designated School Official (DSO). Does not reduce OPT months unless used full-time for 12 or more months.
- PGWP — Post-Graduation Work Permit (Canada)
- Open work permit allowing work with any Canadian employer after graduation. Duration matches the length of the study program, up to a maximum of 3 years for a 2-year MSc. This is the cornerstone of Canada's attractiveness for Indian DS graduates pursuing immigration.
- Express Entry and CRS (Canada)
- Canada's federal immigration selection system. The Comprehensive Ranking System (CRS) scores candidates on age, education, language proficiency, and Canadian work experience. Data Scientists under TEER 1 (NOC 21211) receive priority. Canadian study and work experience adds 50–200+ CRS points toward an Invitation to Apply for PR.
- TEER 1 and NOC 21211 (Canada)
- National Occupational Classification for Data Scientists in Canada. TEER 1 represents the highest-skilled occupation tier. This classification qualifies graduates for all Federal Express Entry streams and most Provincial Nominee Programs — the core of Canada's immigration advantage for DS graduates.
- Graduate Visa (UK)
- UK's 2-year post-study work visa (3 years for PhD graduates). Automatically available after completing a UK degree. No employer sponsorship is required during this period. Graduates may work at any skill level, then transition to the Skilled Worker Visa with employer sponsorship after 2 years.
- Subclass 485 — Temporary Graduate Visa (Australia)
- Allows Australian DS graduates to live and work in Australia for 2–4 years after graduation. Duration depends on institution type and whether regional study was undertaken. This visa is the platform for skilled migration PR applications via Subclass 189 (Skilled Independent) or 190 (State Nominated).
- MLTSSL (Australia)
- Medium and Long-Term Strategic Skills List. Data Scientists and closely related roles are listed — enabling the Skilled Independent Visa (189), Employer Nominated (186), and various State Nominated (190) migration pathways. This designation confirms DS as a national immigration priority occupation in Australia.
- EU Blue Card
- EU-wide work and residence permit for highly-qualified non-EU workers. Requires a job offer above a defined salary threshold (Germany: €56,400 in 2024). Valid across most EU member states. Leads to permanent residence eligibility in Germany in 21 months, or 33 months under the standard pathway.
- Green List Tier 1 (New Zealand)
- New Zealand Immigration's highest-priority occupation category. Data Scientists are listed on Tier 1, enabling the Straight to Residence Visa without requiring a prior job offer. This is one of the world's most favourable immigration positions for skilled DS graduates.
- SOP — Statement of Purpose
- Critical admissions essay for DS programs, particularly in the USA, Canada, UK, and Germany. Must clearly articulate research interests, technical expertise, and career goals. Typically 500–1,000 words. Among the most heavily weighted factors in competitive DS program admissions decisions.
- IELTS, TOEFL, and PTE
- English language proficiency tests. Most DS programs require IELTS 6.5–7.0 overall, or TOEFL iBT 90–100+. PTE Academic is accepted by most Australian and Canadian universities. The Duolingo English Test (DET) is increasingly accepted by US programs since 2020.
- MEXT Scholarship (Japan)
- Japanese Government scholarship for international students. Covers 100% of tuition plus a JPY 147,000/month living stipend and return airfare. One of the most generous academic scholarships in the world. Applied through the Indian Embassy. Requires 8.5+ CGPA and a strong research background to be competitive.
- MBZUAI Scholarship (UAE)
- Mohamed Bin Zayed University of AI fully-funded scholarship for MSc and PhD students. Covers 100% of tuition, accommodation, a monthly living stipend, and comprehensive health insurance. Open to Indian applicants. Regarded as one of the best-funded AI/DS scholarships globally, and one of the rarest opportunities for Indian students in 2024–25.
