How to Get Post-Study Work Permit in the USA : OPT Explained For Indian Students

The United States doesn’t use the term “post-study work visa” the way the UK, Canada, or Australia do. What the US has instead is called OPT – Optional Practical Training. It’s not technically a separate visa.

It’s an employment authorization that operates within your existing F-1 student visa status, allowing you to work in the US for a defined period after graduation.

Understanding how it works, how to apply for it, and – importantly – what happens if you’re a STEM graduate is essential planning for any Indian student studying in the US.

What OPT Is

OPT is a period of temporary employment that is directly related to your major area of study. It’s authorized by the US Citizenship and Immigration Services (USCIS) and applied for through your Designated School Official (DSO) at your university.

There are two types: Pre-Completion OPT, which can be used before you graduate while still enrolled, and Post-Completion OPT, which is what most people refer to when they say OPT – the work authorization period after you finish your degree.

For post-completion OPT, the standard authorization period is 12 months for all international students regardless of degree level. If you have a degree in a STEM field, you can apply for a STEM OPT Extension that adds 24 months to your authorization – giving a total of 36 months of work authorization after graduation.

This 36-month window for STEM graduates is one of the most significant advantages the US has over other study destinations for Indian students in technology, engineering, data science, and the natural sciences. It gives you nearly three years to find employment, transition to an H-1B visa, and build a US career foundation.

The STEM OPT Extension: What Qualifies

Not every degree labeled “science” or “engineering” automatically qualifies for the 24-month STEM extension. Your specific degree program must appear on the STEM Designated Degree Program List published by the US Department of Homeland Security.

The DHS STEM list includes programs in computer science, information technology, electrical engineering, mechanical engineering, chemical engineering, civil engineering, biology, physics, chemistry, mathematics, data analytics, artificial intelligence, and a range of other technical and scientific disciplines.

Degrees in business management, economics, or social sciences typically do not qualify, even if they contain quantitative components.

Before assuming you qualify, verify that your specific degree program’s CIP code appears on the current DHS STEM list. Your DSO can confirm this.

Eligibility Requirements

To be eligible for OPT, you must have been enrolled full-time for at least one full academic year (nine months) on an F-1 student visa.

You must not have used more than 12 months of full-time Curricular Practical Training (CPT) at any point during your studies – using 12 or more months of full-time CPT makes you ineligible for OPT.

Your OPT employment must be directly related to your degree field. A computer science graduate working as a software developer qualifies. The same graduate working in retail does not.

The relationship between the job and the degree is assessed at the program level, not strictly at the task level – it doesn’t need to be a perfect match but it does need to be in the same general field.

You cannot be unemployed for more than 90 days total during your standard 12-month OPT period. For STEM OPT extension holders, the limit is 150 days total across the entire 36-month period.

Exceeding these unemployment limits causes your F-1 status to terminate, which has serious immigration consequences.

How to Apply : Step by Step

The OPT application process requires careful timing because the EAD (Employment Authorization Document) is the card you need in hand before you can legally start working, and USCIS processing times must be factored in.

• Step 1 : Request a new I-20 from your DSO

Visit your university’s international student services office and request an OPT recommendation from your DSO. Your DSO will update your SEVIS record and issue a new I-20 with a page showing the OPT recommendation.

• Step 2 : Complete Form I-765

Form I-765, Application for Employment Authorization, is the USCIS form for OPT. Download the current version from uscis.gov – forms are periodically updated and old versions are rejected.

Fill it out carefully. Errors on I-765 are a common source of delays and Request for Evidence (RFE) notices. Your DSO can review your completed form before submission.

• Step 3 : Compile your application package

The complete application requires: the completed I-765 form, a filing fee (currently USD 470 – verify the current fee on uscis.gov as this changes), two passport-style photographs, a copy of your passport biographical page, a copy of your F-1 visa stamp, copies of all previous I-20 forms you’ve had, copies of any previous EADs if applicable, and your new OPT-recommended I-20.

• Step 4 : Submit within the application window

You can submit your OPT application as early as 90 days before your program end date and as late as 60 days after your program end date. The ideal timing is to submit 90 days before your graduation date, which gives USCIS the maximum processing time before your employment start date.

The most common mistake students make is waiting until after graduation to apply. USCIS processing times for OPT typically run three to five months currently. If you submit after your degree ends, you may not receive your EAD until months into your post-graduation period, during which you cannot legally work.

• Step 5 : Set your employment start date

On your I-765, you choose your requested OPT start date. This date must be within 60 days after your program end date and cannot be before your program end date. Once set, this date cannot be changed. Your 12-month clock starts ticking from this date regardless of when you actually find a job.

• Step 6 : Wait for USCIS and receive your EAD

USCIS processes the application and mails your EAD to the address you listed on the form. You cannot start work until you have the physical EAD in hand and your start date has arrived.

The STEM OPT Extension Application

If you qualify for the STEM extension, you must apply before your initial 12-month OPT expires. You cannot apply for the extension after expiration.

The extension application requires a new I-765, the STEM extension filing fee, a training plan on Form I-983 completed jointly with your employer (your employer must be registered on E-Verify, the federal employment eligibility verification system), and confirmation that you have a job in your STEM field.

The employer’s E-Verify registration is a requirement that catches some students off guard. Not all US employers are registered with E-Verify, and without it, they cannot sponsor your STEM extension. Before accepting a position intending to use your STEM extension, verify the employer’s E-Verify status.

USCIS allows you to continue working beyond your initial OPT expiration for up to 180 days while your timely-filed STEM extension is pending. This automatic extension of work authorization is only available if you applied for the STEM extension before your initial OPT expired.

What Happens After OPT : The H-1B Question

For most Indian students who want to build a long-term career in the US, the H-1B work visa is the next step after OPT. The H-1B allows sponsored employment in a specialty occupation and is the most common work visa for technology and professional services workers in the US.

The complication is that H-1B visas are subject to an annual cap of 85,000 visas, and there are significantly more applicants than available visas.

Selection is done by lottery each April for employment starting October 1. The odds of selection in any given year vary but have historically been significantly below 50% for most applicants.

Indian nationals face an additional challenge. The employment-based green card backlog for Indian nationals is extraordinarily long – due to per-country caps in the immigration system, Indian nationals in the employment-based second and third preference categories face waiting times that can stretch to decades.

The honest framing: OPT gives you an opportunity to establish yourself in the US job market and apply for H-1B lottery selection.

Whether you ultimately build a long-term career in the US depends on H-1B lottery luck in the short term and eventually navigating the green card backlog.

Many Indian professionals spend years on H-1B status waiting for permanent residency progression.

For students who value certainty about long-term residency, Canada’s Express Entry or Australia’s skilled migration pathways offer more predictable timelines than the US system.
