CPT vs OPT: the real difference nobody explains (2026 updated guide)

Planning your study journey in the United States means understanding how work authorisation actually works. You’ve likely heard advice from seniors, online forums, and well-meaning relatives, yet the CPT vs OPT conversation still feels unclear.

This 2026-updated guide breaks it down in plain language. Whether you’re just starting an F-1 programme or planning internships and post-study work, this walkthrough gives you the clarity most students only gain after learning the hard way.

Why CPT and OPT matter more than ever

Work experience continues to play a major role in how international graduates stand out in competitive job markets. US employers value real-world exposure, whether that comes from:

• a summer internship through CPT, or

• a post-study role through OPT.

Each option has specific rules, timelines, and limits that can affect your degree planning, job search, and long-term visa prospects. Understanding these differences early can save you stress later.

CPT vs OPT at a glance

Here’s the simplest way to think about it:

Curricular Practical Training (CPT): Work authorisation during your degree, tied directly to your curriculum.

Optional Practical Training (OPT): Work authorisation after your degree, or shortly before graduation, not tied to coursework.

The real complexity sits beneath these definitions.

CPT: what students actually need to know

CPT is part of your academic programme

CPT exists because your university recognises certain work experiences as academically relevant. This means:

• The role must relate to your degree

• Your Designated School Official (DSO) must approve it

• It must appear on your I-20

CPT is academic training, not a separate work visa.

Full-time vs part-time CPT

• Part-time CPT: up to 20 hours per week

• Full-time CPT: more than 20 hours per week

The rule students often misunderstand:

• 12 months of full-time CPT removes OPT eligibility

• Part-time CPT does not affect OPT

This distinction should guide how long you accept full-time internships.

When you can use CPT

Most students must complete one academic year before using CPT, unless:

• The programme formally requires practical training from the start.

Each university sets its own CPT policy, and some apply stricter rules than USCIS.

CPT does not require a USCIS application

One major advantage of CPT is speed:

• No USCIS filing

• No government fees

• Faster approval handled by your DSO.

This flexibility helps when internship timelines move quickly.

OPT: Your bridge to post-study work

OPT is not tied to coursework

OPT allows you to work after completing your degree, or near the end of it. Students receive:

• Up to 12 months of OPT per degree level

OPT requires a USCIS application

OPT involves a formal process:

• DSO recommendation

• USCIS filing and fees

• Approval wait that can take time

Applications can be submitted:

• Up to 90 days before your programme end date

• Up to 60 days after programme completion.

Early planning remains important in 2026.

OPT requires a USCIS application

OPT involves a formal process:

• DSO recommendation,

• USCIS filing and fees, and

• Approval wait that can take time.

Applications can be submitted:

• Up to 90 days before your programme end date

• Up to 60 days after programme completion

Early planning remains important in 2026.

OPT job relevance is more flexible than CPT

Your OPT role must relate to your field of study, but:

• It does not need to be part of your curriculum

• It does not need school pre-approval

• Employers have more flexibility in role structure

This is why OPT remains the most popular route for launching a US career.

STEM OPT extends your time

Students in STEM-designated programmes can apply for a 24-month extension, bringing total OPT time to 36 months.

This additional period helps students:

• Gain deeper industry experience,

• Strengthen H-1B prospects, and

• Build long-term career momentum.

CPT vs OPT: the differences students rarely hear clearly

CPT affects your study rhythm; OPT affects your career launch

CPT requires balancing:

• Classes

• Assignments

• Work hours

OPT allows you to focus fully on employment.

Job-offer rules differ

• CPT does not require a job offer under USCIS rules, though most universities do.

• OPT does not require a job offer at the time of application.

Unemployment limits apply only to OPT

• 90 days of unemployment on standard OPT

• 150 days total across OPT and STEM OPT

CPT has no unemployment limit.

Payment rules vary

• CPT roles may be paid or unpaid, depending on school and labour rules.

• OPT roles may also be unpaid, but still count toward unemployment limits.

Mistakes have different consequences

• CPT errors can immediately jeopardise F-1 status.

• OPT errors usually affect approval timing or eligibility.

Both require careful planning.

Common CPT and OPT myths

• “CPT always reduces OPT.” Only 12+ months of full-time CPT does.

• “OPT guarantees a work visa.” OPT is not a visa category.

• “STEM OPT is automatic.” It requires a qualifying degree, an E-Verify employer, and Form I-983.

How to choose between CPT and OPT

Use CPT if you want to:

• Gain internship experience during your degree

• Complete a required practicum

• Explore industries before graduation

Use OPT if you want to:

• Start a full-time career in the US

• Build long-term professional experience

• Use the STEM OPT extension

Many students use both strategically.

Timeline planning students often overlook

• CPT rules vary widely by university.

• OPT processing times change year to year.

• Your job search strategy should align with your work authorisation type.

Planning early remains one of the biggest advantages students have.
