Day 1 CPT vs. OPT: Key Differences Every Student Should Know

If you’re an international student on an F-1 visa, you’ve likely heard about both Curricular Practical Training (CPT) and Optional Practical Training (OPT). But what about Day 1 CPT? How is it different from OPT? Which is better for your situation?

This guide explains the key differences between Day 1 CPT and OPT, helping you make informed decisions for your education and career.

What is Day 1 CPT?

• Curricular Practical Training (CPT) allows students to work in roles directly related to their degree.

• At Day 1 CPT universities, eligible graduate students can begin CPT work authorization from their first semester.

• Often structured in hybrid programs, where students attend on-campus classes once per semester.

What is OPT?

• Optional Practical Training (OPT) is temporary work authorization after completing your degree.

• Standard OPT = 12 months.

• STEM OPT Extension = up to 24 additional months.

• OPT can only begin after your program completion (post-completion OPT) or after one academic year (pre-completion OPT).

Day 1 CPT vs. OPT: Key Differences

Feature	Day 1 CPT	OPT
When You Can Start	From the first semester	After 1 year of study or post-graduation
Authorization Type	Part of degree program	Post-completion work authorization
STEM Extension	Not applicable	Yes, up to 24 months
Duration	Program-specific	12 months (plus STEM extension if eligible)
Purpose	Practical training as part of curriculum	Work experience after studies

Which One is Right for You?

• Choose Day 1 CPT if you want to start working while studying.

• Choose OPT if you want to focus on full-time work after graduation.

• Many students actually benefit from both—CPT during studies and OPT after graduation.

Many students benefit from engaging in both day 1 CPT and OPT. To remain eligible for OPT you must limit any full-time CPT to under 12 months. Thus, allowing you to gain practical experience while you study and after graduating.

Final Thoughts

Understanding Day 1 CPT vs. OPT is essential for planning your U.S. education and career pathway. Each option has its advantages, and the best choice depends on your program and long-term goals.
