Day 1 CPT is technically legal under USCIS regulations, but it is not without risk. Your employer must be certified for CPT participation.

Does Day 1 CPT affect my OPT eligibility?

No. Day 1 CPT does not reduce your OPT period. You still get 12 months of OPT after graduation, regardless of any prior CPT.

Can I do Day 1 CPT after I've already used OPT?

No. Once you're on post-completion OPT, you cannot go back to CPT. However, you can switch during school if the opportunity arises.

What Is Day 1 CPT?

Day 1 CPT refers to programs at certain universities that authorize Curricular Practical Training from the first day of enrollment. Unlike traditional CPT (which requires one academic year of enrollment first), Day 1 CPT programs integrate employment into the curriculum as a mandatory or elective component.

How it works

You enroll in a masters or doctoral program that includes a practicum/co-op component from Day 1. The school authorizes CPT on your I-20, and you can start working immediately.

Common degrees

MBA, MS in Computer Science, MS in Information Technology, MS in Data Science at specific universities offering Day 1 CPT.

School examples

Several smaller private universities offer Day 1 CPT programs. Popular ones include programs in the MBA and tech space.

Risks of Day 1 CPT

12 months of full-time CPT eliminates OPT eligibility

If you use 12+ months of full-time CPT, you are NOT eligible for post-completion OPT. This eliminates your 12-month (or 36-month STEM) OPT pathway.

USCIS scrutiny on H-1B and green card applications

USCIS may request extensive evidence about the legitimacy of your Day 1 CPT program when reviewing future immigration benefits.

School accreditation concerns

Some Day 1 CPT schools have faced scrutiny from SEVP. If a school loses its SEVP certification, students' SEVIS records can be terminated.

Tax and legal complications

Some Day 1 CPT arrangements may create tax complications or questions about the legitimacy of the educational program.

When OPT Is the Better Choice

You want the standard, safest immigration pathway (OPT → STEM OPT → H-1B)

You have a STEM degree and want 36 months of work authorization

You plan to pursue long-term immigration (green card, O-1)

You don't want additional tuition costs for a second masters program

You want no extra scrutiny on future USCIS applications
