Curricular Practical Training (CPT) Internship Rules & Eligibility
Updated 31 August 2026 Ā· 2 min read
Executive Summary: What is CPT Internship Authorization?
Curricular Practical Training (CPT) is an official federal work authorization (8 CFR 214.2(f)(10)) that allows international students on an F-1 Visa to engage in paid off-campus internships and co-op jobs directly related to their Master's degree field.
Here is what Indian families need to know upfront:
- The 9-Month Academic Requirement: You must complete one full academic year (2 consecutive semesters / approx 9 months) in the US before becoming eligible for CPT off-campus work. Fall intake students are eligible for summer CPT; Spring intake students must wait until their second summer (Fall vs Spring Intakes Guide).
- CPT Earnings Pay Off Living Outlays: Paid CPT summer internships in tech, data science, and engineering pay between $35 and $55 per hour ($5,000 to $9,000/month). Earning $12,000 to $18,000 over a 12-week summer internship allows Indian students to cover an entire year of living expenses!
- Beware of the 12-Month Full-Time CPT Trap: If you accumulate 12 months (365 days) or more of Full-Time CPT, you completely FORFEIT your post-graduation OPT and 3-Year STEM OPT work authorization! Always keep total full-time CPT under 364 days.
