Optional Practical Training



Optional Practical Training (OPT) is a temporary job training opportunity that must be directly related to an F-1 student's major area of study. It is intended to provide a student with practical experience in his or her field of study upon completion of a degree program.

You may apply for OPT and, if approved, you will be authorized to engage in OPT on the dates listed on your Employment Authorization Document (EAD).

The two types of OPT are:

1. OPT for STEM (Science, Technology, Engineering, Mathematics) field students. These students are eligible for an initial 12 months of post-completion OPT and may be eligible for a 24-month STEM extension.

2. Non-STEM field students. These students are eligible for 12 months of post-completion OPT. There is no extension available.

  • OPT is available to you, if you are a F-1 student who has completed a degree program.
  • OPT is available to you, if you have been in valid immigration status for nine months.
  • If you are eligible and wish to apply for post-completion OPT, you must complete an online OPT workshop offered by International Affairs (IA). You must also pass an OPT quiz following the OPT workshop. The workshop and quiz can be logged into in your Canvas account.

Regular paid employment

  • You must work at least 20 hours per week.
  • You may work for multiple employers, as long as all employment is directly related to your program of study.

Work for hire

  • Student and Exchange Visitor Program regulations (SEVP) state, "This work for hire is also commonly referred to as 1099 employment where an individual performs a service based on a contractual relationship rather than an employment relationship. If requested by Department of Homeland Security (DHS), students should be prepared to provide evidence showing the duration of the contract periods and the name and address of the contracting company."

Self-employed business owner

  • SEVP regulations state, "Students on OPT may start a business and be self-employed. The student should be able to prove that he or she has the proper business licenses and is actively engaged in a business related to his or her degree program."

Employment through an agency or consulting firm

  • SEVP regulations state, "Students on post-completion OPT must be able to provide evidence showing they worked an average of at least 20 hours per week while employed by the agency."
  • STEM OPT extensions are not allowed for multiple employer arrangements, sole proprietorships, employment through “temp” agencies, employment through consulting firm arrangements that provide labor for hire, and other relationships that do not constitute a bona fide employer-employee relationship. STEM OPT rule states that "students cannot qualify for STEM OPT extensions unless they will be bona fide employees of the employer signing the Training Plan, and the employer that signs the Training Plan must be the same entity that employs the student and provides the practical training experience.”

Volunteers or unpaid interns

  • SEVP OPT policy guidance states that "Students may work as volunteers or unpaid interns, where this practice does not violate any labor laws. The work should be at least 20 hours per week for students on post-completion OPT. A student should be able to provide evidence, acquired from the student's employer, to verify that he or she worked at least 20 hours per week during the period of employment."
  • Although volunteering may appear simple, it can be very complex and could have many pitfalls that could result in risking your international immigration status. Please refer to the IA's Employment and Volunteering page.
  • You may apply for post-completion OPT up to 90 days before your program end date and up to 60 days after your program end date. The application must be properly filed and in a timely manner with the correct USCIS Service Center.
  • If the application is not received by USCIS by the 60-day deadline, you will lose OPT eligibility. In addition, the application must be properly filed within 30 days of the date your International Student Advisor recommends OPT in SEVIS and creates an OPT I-20.
  • Once you have completed your academic program, you may not engage in any type of unpaid/paid employment until you have received your approved OPT/EAD card.
  • If you are an undergraduate or non-thesis MS graduate student, the completion date for you is the date of graduation for that semester.
  • If you are a MS or PhD graduate student in a thesis or dissertation program, the completion date for you is defined as the date when you submit the library copy of your thesis or dissertation.
  • You may only work during the dates authorized on your EAD.
  • You may not accrue more than 90 days of unemployment during the initial 12 month OPT period in order to remain in valid F-1 status.
  • Participate in the online OPT workshop offered by IA in your Canvas account.
  • Pass the OPT quiz which follows the Canvas workshop.
  • Obtain the OPT application packet from the OPT workshop.
  • Complete the OPT application using black ink.
  • Obtain required signatures from your academic advisor, your department chair, and the Office of Graduate Studies. (Signatures from the Office of Graduate Studies are only required for graduate students.)
  • Submit completed forms to either the front desk of International Affairs or directly to your International Student Advisor. Your advisor will review the OPT packet and, if accurate and complete, will process an OPT I-20.
  • When the I-20 is complete, you will collect the new OPT I-20.
  • You are responsible for mailing OPT application and other required documents to USCIS.

  • Travel during the application pending period is not advised since the your OPT application could be considered abandoned and, therefore, invalid. This could result in you not being allowed re-entry to the United States.

 After OPT is approved

  • If you travel outside the United States after the OPT is approved and you do not have a job offer, you may be denied re-entry into the United States.
  • If you are employed, time spent outside the United States during OPT counts as unemployment against the 90-day limit, unless you are either:
    • Employed during a period of leave authorized by an employer.
    • Traveling as part of your employment.
  • While traveling outside the U.S. you should have in your possession your original I-20 with travel authorization signature, OPT/EAD card, and proof of employment (letter from employer or most recent pay stub).
  • Academic department contacts
  • Internet search
  • Networking

On March 11, 2016 the Department of Homeland Security (DHS) published new regulations for F-1 STEM (Science, Technology, Engineering, and Mathematics) OPT employment authorization. The new regulations became effective on May 10, 2016. In summary, key aspects of the new regulations consist of the following:

  • STEM extension was increased to 24 months from 17 months previously. That means that total OPT time is 36 months (12 for the original post-completion OPT benefit and 24 months for the STEM extension).
  • There is a second STEM extension after a student completes a subsequent higher STEM degree. The new 24-month extension permits students to have two STEM extensions in their lifetimes based on two separate STEM eligible degrees. For example, if a student has received a STEM extension for a BS degree, and then completes a higher degree in a STEM field, the student will qualify for a second STEM extension in the higher degree field.
  • STEM extensions may be based on a previous degree. In short, if a student has never applied for the STEM extension for a lower STEM-based degree, the student can qualify for a STEM extension as long as he/she is eligible for post-completion OPT for the new non-STEM based degree. Please review the number 4 criteria below to determine if you qualify for a STEM extension based on a previous degree.
  • The limit on unemployment has been expanded from 30 days to 60 days for the  24-month STEM OPT extension period.
  • Consulting, self-employment, and volunteering do not qualify as eligible employment for STEM. NAFSA-81 FR 13079 – “There are several aspects of the STEM OPT extension that do not make it apt for certain types of arrangements, including multiple employer arrangements, sole proprietorships, employment through “temp” agencies, employment through consulting firm arrangements that provide labor for hire, and other relationships that do not constitute a bona fide employer-employee relationship”.
  • The I-765 filing deadline is increased from 30 to 60 days after the Designated School Official’s (International Student Advisor’s) recommendation on the OPT I-20.
  • A new Form I-983 Training Plan is required to be completed by the OPT STEM extension employer in order to qualify both the student and the employer for STEM OPT eligibility.

You are currently eligible to apply for the 24-month STEM OPT extension

The new rules governing STEM OPT extension took effect on May 10, 2016. If you are currently on post-completion OPT and you are in a STEM field and you applied on or after May 10, 2016, you are eligible for the STEM OPT 24-month benefit.

  • You must apply for the STEM OPT extension prior to the expiration of your current OPT.
  • Your employer will have to complete the Form I-983, Training Plan, before you can submit the STEM OPT application to USCIS.

How to qualify for a STEM extension based on a prior STEM degree

  • You received both degrees from currently accredited and SEVP-certified institutions.
  • Your previous degree cannot have been conferred more than ten years ago at the time of your OPT extension application.
  • You have not already received STEM OPT extension based on this previous degree.
  • Your practical training opportunity is directly related to the previous obtained STEM degree.
  • With the exception of the requirement that your employer participate in the eVerify program and the employer’s completion in the I-983 Training Plan, the process for the STEM extension is the same as the process of the post-completion OPT.
  • If you are eligible and interested in applying for the 24-month STEM OPT extension, it is important that you and your employer begin working on the Form I-983 Training Plan now, as it will require additional time to prepare the form for submission with the rest of the STEM OPT extension application. For more information about the new Form I-983 Training Plan for STEM OPT students, you may visit Form I-983 Overview
  • Once you have completed your STEM OPT application packet, and your employer has completed the Form I-983, you may submit the packet to your International Student Advisor. Your International Student Advisor will review all forms for completion and accuracy, and will begin preparing your recommended updated I-20 for the additional time you request or for the 24-month period.
  • You will be contacted by International Affairs when your STEM OPT I-20 form is ready. 
  • For more information about the new STEM OPT extension regulations, and a step-by-step guide to completing the Form I-983 Training Plan, you may visit the STEM OPT hub

If you were physically in the U.S. in F or J status anytime between January 1 - December 31, 2018, you're obligated to send one form, Form 8843, to the U.S. tax agency Internal Revenue Service (IRS), even if you had no income. For the 2018 tax season, if you earn $1 of U.S. source income or greater, you may need to file a federal tax return with the IRS. Depending on your individual circumstances, you may also need to file a state tax return(s).  You may also visit the IRS webpage for more information on taxation of Nonresident Aliens.



April 15th is the last day for residents and non-residents who earned U.S. income to file Federal tax returns for each calendar year.



Generally, most international students & scholars who are on FJM or Q visas are considered non-residents for tax purposes. International undergraduate students on J1 & F1 visas are automatically considered non-resident for their first 5 calendar years in the US, whilst Scholars/Researchers on J visas are automatically considered non-residents for 2 out of the last 6 calendar years in the US. If you’ve been in the US for longer than the 5 or 2 year periods, the Substantial Presence Test will determine your tax residency.



You may qualify for tax exemptions if your home country has a tax treaty with the United States. 



The Office of International Affairs (OIA) has partnered with Sprintax to assist international students and scholars at Missouri S&T to complete their federal income tax forms.  Once the software is available, OIA will email all international students the current tax year’s access code and instructions for utilizing Sprintax.  Sprintax access codes used in previous years will not work for utilizing the software for the current tax year.  Sprintax is typically available by the end of February each year.  Please note that OIA and all other university staff are not qualified or allowed to provide individual tax advice.



**DISCLAIMER: The Office of International Affairs and the university are NOT permitted to assist any student/scholar with any IRS tax form preparation or tax-related questions.  The information provided is intended for your benefit.  Any questions or concerns should be directed to Sprintax, a certified tax preparer or a local IRS field office.
