Day One CPT (Curricular Practical Training) is becoming an increasingly popular option for international students in the United States, especially those pursuing graduate programs while looking to gain immediate work experience. This guide will walk you through the key details of Day 1 CPT, the application process, important immigration rules like the 150-day and 60-day rules, and how it relates to H1B sponsorships and job flexibility.
What Is Day 1 CPT?
Day 1 CPT allows eligible international students in F-1 visa status to begin Curricular Practical Training (CPT) from the first day of their academic program. Unlike traditional CPT, which typically requires completion of at least one academic year before engaging in off-campus work, Day 1 CPT is offered by certain U.S. universities through programs where practical training is a core part of the curriculum. It is particularly appealing to working professionals seeking to maintain legal work authorization while pursuing further education.
Day 1 CPT Application Step-by-Step Procedure
Applying for Day 1 CPT requires careful attention to detail and compliance with university and immigration guidelines. Here is a step-by-step procedure:
- Choose a CPT-Eligible University
Look for SEVP-approved universities that explicitly offer Day 1 CPT programs. Some popular options include Harrisburg University, University of the Cumberlands, and Campbellsville University. - Apply and Get Admitted
Submit your application with required documents like transcripts, test scores (if needed), résumé, and a Statement of Purpose. Once admitted, you’ll receive an I-20 form with CPT noted on it. - Secure a Job Offer Letter
CPT is employment-specific, so you must have a job offer directly related to your field of study. The letter should include details such as job title, duties, start date, location, and supervisor information. - Request CPT Authorization from DSO
Your Designated School Official (DSO) will review your job offer and program eligibility, then update your SEVIS record and issue a new I-20 with CPT authorization. - Begin Working Legally from Day 1
Once you receive your CPT-authorized I-20, you may start working on or off campus from the first day of your program.

What is the 150-Day Rule?
The 150-day rule affects students who are applying for a change of status (such as F1 to H1B). According to USCIS, if an individual files a change of status application, they must be in valid status for at least 150 consecutive days before their H1B petition is approved with a change of status.
For Day 1 CPT students, this means your F1 status, maintained through continuous enrollment and CPT authorization, must be valid for at least 150 days leading up to the H1B filing window (usually April).
What is the 60-Day Rule?
The 60-day rule applies to F1 students after completing their program or when they stop attending school. You are given a 60-day grace period to:
- Leave the U.S.
- Transfer to another school
- Change your visa status
If your Day 1 CPT program ends and you do not take action within this 60-day window, you risk falling out of status.
What Are the Well-Known Companies That Sponsor H1B Visas for Day 1 CPT Employees?
Many reputable companies sponsor H1B visas, and hiring candidates on Day 1 CPT is not unusual, provided everything is legally compliant. Well-known H1B sponsors include:
- Amazon
- Microsoft
- IBM
- Apple
- Deloitte
- Infosys
- TCS
- Capgemini
- Cognizant
It’s crucial to work with companies that have a good track record of H1B filings and understand the nuances of Day 1 CPT employment.
Can You Switch to a Different Company During CPT?
Yes, you can switch employers during CPT, but you must:
- Obtain a new job offer letter that aligns with your field of study.
- Inform your DSO immediately.
- Get a new CPT authorization and updated I-20 before starting with the new employer.
Working without updated authorization is a violation of your F1 status and could have serious immigration consequences.
When Can You Apply for CPT?
You can apply for CPT as soon as:
- You are enrolled in a CPT-eligible program where practical training is an integral part of the curriculum.
- You have a valid job offer.
- The university policy allows Day 1 CPT (i.e., from the first day of the program).
Make sure to submit your CPT request before beginning any work. Retroactive CPT is not allowed.
Conclusion
Day One CPT can be a strategic option for international students who want to work while studying in the United States. However, it’s essential to stay informed, work with accredited universities, maintain your F1 status, and follow USCIS regulations strictly. Whether you’re planning to transition to an H1B visa or simply want to enhance your career while studying, understanding the full scope of Day 1 CPT will help you make smarter, safer decisions.
