What Employers Should Know About Hiring International Students


Many employers are concerned about liability issues related to the employment of international students in the United States due to changes in federal laws governing non-citizens. This information addresses concerns employers might have about international students and employment.

Getting permission for international students to work in the US is not as difficult as many employers think. Most international students are in the US on non-immigration student visas (F-1 and J-1), and these international students are eligible to accept employment under certain conditions.

Practical Training for F-1 Students is a legal means by which F-1 students can obtain employment in areas related to their academic field of study. Students, in general, must have completed one academic year (approximately 9 months) in F-1 status and must maintain their F-1 status to be eligible for practical training. There are two types of practical training:

  1. Optional Practical Training (Post-Completion)
  2. Curricular Practical Training

Optional Practical Training (OPT) must be authorized by the US Citizenship & Immigration Services (USCIS) based on a recommendation from the designated school official (DSO) at the school which issued the I-20 to the student. Form I-20 is a government document which verifies the student's admission to that institution. Students are eligible for 12 months of OPT for each degree level. Students who obtain a degree in Science, Technology, Engineering, and Mathematics (STEM) may be eligible for an additional 24 months of OPT. Post-Completion OPT can be authorized for full time employment after completion of the course of study.

STEM OPT Extension can be authorized for an additional 24 months if student:

  • is currently on post-completion OPT
  • has completed all course requirements (excluding thesis or equivalent) for a bachelor's, master's or doctoral degree in STEM
  • has a job or jon offer (must be at least 20 hours per week) from an employer registered in the USCIS E-verify program

Employer responsibilities for STEM:

  1. report to Designated School Officials (DSO) within 5 business days if the student has been terminated from, or otherwise leaves, employment prior to the end of the authorized period of OPT
  2. participate in the E-verify program
  3. have a Federal Employer Identification Number
  4. agree to the terms of STEM OPT by completing their sections of the Training Plan (I-983)

Cap-Gap OPT can be granted if student (1) is in period of authorized post-completion OPT, and (2) is the beneficiary of a timely filed H-1B petition requesting change of status and an employment start date of October 1 of the following fiscal year. The Cap-Gap OPT is an automatic extension of duration of status and employment authorization to bridge the gap between the OPT and the start of the H-1B status. The automatic extension of OPT is terminated upon the rejection, denial, or revocation of the H-1B petition.

Employment Authorization Document (EAD): Students who have recieved OPT permission will be issued an EAD by the USCIS. Their name, photo and valid dates of employment are printed on the EAD. Employers should note that the average processing time for USCIS to issue the EAD is two or three months, and students may begin employment only after they recieve the EAD which will indicate the start and end dates of employment. Students who have a pending STEM extension application can continue working for up to 180 days while the application is pending.

Curricular Practical Training (CPT) may be authorized in the institution (NOT by USCIS) for F-1 students participating in curricular-related employment such as cooperative education, work study, practicum and internship programs.

Authorization is indicated on page 2 of the I-20 and includes the name of the company, start and end dates, and signature of the designated school official (DSO). Since each institution has different policies related to curricular-related employment, students should speak to the DSO at their institution. Processing time for the authorization of CPT varies at each institution, and students may begin employment only after they receive the CPT work authorization on their I-20. International students on F-1 visas are eligible for both CPT before finishing their studies, as well as 12 months of OPT. However, students who work full-time on CPT for one year or more are not eligible for OPT.

Academic Training for J-1 Students:

International students on J-1 visas are eligible for up to 18 months of work authorization, called academic training. Post-doctoral students may apply for an additional 18 months of academic training. Some J-1 program participants are also allowed to work part-time during the academic program. Students should consult with the Responsible Officer (RO) or Alternate Responsible Officer (ARO) at their institution.

Minimal Paperwork for the Employer: Fortunately, there is little paperwork for an employer who hires F-1 or J-1 students. All paperwork is handled by the students, the school, and USCIS (for OPT).

Continuing Employment after the Practical/Academic Training Period: Federal regulations require that students terminate their employment at the conclusion of the authorized practical or academic training. However, students on an F-1 visa, or students on a J-1 visa who are not subject to the two-year home residency requirement, may continue to be employed, if they recieve approval for a change in visa category - usually to an H-1B. Students must have a minimum of a bachelor's degree in order to quality for the H-1B status.

Individiuals may be work in the US for a maximum of six years under an H-1B visa. This visa is only valid for employment wiht the company that petitioned for them. They must re-apply to the USCIS if they wish to change employers. As soon as the initial job offer is made, they should petition for an H-1B visa if employment is likely to extend beyond the practical training period.

What about Taxes: Unless exempt due to a tax treaty, F-1 and J-1 students earning income while working on practical training are subject to applicable federal, state, and local income taxes. Information on tax treaties may be found in Internal Revenue Services Publication 519, US Tax Guide for Aliens, and 901, US Tax Treaties.

Generally, F-1 and J-1 students are exempt from Social Security and Medicare tax requirements. However, if the F-1 and J-1 students are considered "resident aliens" for income tax purposes, Social Security and Medicare taxes should be withheld. Chapter 1 of the Internal Revenue Services Publication 519, US Tax Guide for Aliens explains how to determine the residency status of international students. More information on Social Security and Medicare taxes can be found in Chapter 8 of Internal Revenue Services Publication 519, US Tax Guide for Aliens and in Section 940 of Social Security Administration Publication No. 65-008, Social Security Handbook.

Frequently Asked Questions:

Isn't it illegal to hire international students because they do not have a green card? No. Federal regulations permit the employment of international students on F-1 and J-1 visas within certain limits. These visas allow students to work in jobs related to their major field of study. F-1 students can work on "practical training"; J-1 students may work on "academic training".

Even if it's legal to hire international students, won't it cost a lost of money and involve a lot of paperwork? No. The only cost to the employer hiring international students is the time and effort to interview and select the best candidate for the job. The international students office handles the paperwork involved in securing the work authorization for the F-1 and J-1 students. In fact, a company may save money by hiring international students because the majority of them are exempt from Social Security (FICA) and Medicare tax requirements.

How long can international students work in the United States on a student visa? F-1 students are eligible for curricular practical training before completing their studies, as well as an additional 12 months of optional practical training following graduation. Students who complete a bachelor's, master's or doctoral degree in a STEM field may work for an additional 24 months of optional practical training with an E-verify employer. However, if they work full-time for one year or more of curricular practical training, they are ineligible to apply for Optional Practical Training. Students with a J-1 visa are usually eligible to work up to 18 months following graduation. They may also be eligible to work part-time during their program of study. The Responsible Officer (RO) or Alternate Responsible Officer (ARO) will evaluate each student's situation to determine the length of time for which they are eligible to work.

Don't international students need work authorization before I can hire them? No. International students must have the work authorization before they begin actual employment, but not before they are offered employment. In fact, J-1 students must have a written job offer in order to apply for the work authorization. Many F-1 students will be in the process of obtaining work authorization while they are interviewing for employment. Students can give employers a reasonable estimate of when they expect to recieve work authorization.

What does the work authorization look like? For Optional Practical Training, F-1 students receive from USCIS an Employment Authorization Document (EAD), a small photo identity card that indicates the dates for which they are permitted to work. For Curricular Practical Training, F-1 students recieve authorization from the school (NOT from USCIS) on the back of the students I-20. "No Service Endoresement is necessary" - per 8CFR 274a.12(b)(6)(iii). For Academic Training, J-1 students receive work authorization from the RO or ARO at their institution on the student's DS-2019.

What if I want to continue to employ international students after their work authorization expires? With a bit of planning ahead, an employer can hire international students to continue to work for them in the H-1B visa category for a total of six years (authorization is granted in two, three-year periods). The H-1B is a temporary working visa for workers in a "specialty occupation". The application procedure to the USCIS is straightforward. The job must meet two basic requirements:

  1. The salary must meet the prevailing wage as defined by the Department of Labor
  2. A bachelor's degree is a minimum normal requirement for the position

Doesn't an employer have to prove that international students are not taking jobs from a qualified American? No. American employers are not required to document that a citizen of another country did not take a job from a qualified American if that person is working under an F-1, J-1 or H-1B visa. Employers must document that they did not turn down a qualified American applicant for the position only when they wish to hire foreign citizens on a permanent basis and sponsor them for a permanent resident status ("green card").

Can I hire international students as volunteer interns? Normally, if the internship involves no form of compensation and is truly voluntary, the students may volunteer without having to do any paperwork with the USCIS. If, however, the internship provides a stipend or any compensation, students must obtain permission for practical training or academic training prior to starting their internship. Students should check with their employers to ensure that the company is allowed by law to offer unpaid internships. More information about unpaid internships can be found on the DOL website at

What is the cost of the E-verify program and how can I enroll in the E-verify program? There is no cost to register in the E-verify program. Information on E-verify and the enrollment procedure can be found on the USCIS website at
