The process at a glance
- 01Year 1 of OPT
Find a sponsor early
Begin applying to H-1B sponsors before your post-completion OPT begins. Filter job boards by "H-1B sponsor" or check the USCIS H-1B Employer Data Hub.
- 02Early March
Employer registers you
Your employer creates a USCIS online registration ($10 fee) listing your passport details. Selection results are released by 31 March.
- 03April–June
Employer files Form I-129
If selected, the employer has a 90-day window to file the full petition with LCA from the Department of Labor, fees, and your evidence (degree, transcripts, passport).
- 04June–September
Wait for approval
Standard processing runs 2–4 months; premium processing (extra fee) returns a decision in 15 calendar days. Cap-gap protects your F-1 status if your OPT expires in this window.
- 051 October
Start H-1B employment
You can begin H-1B work on 1 October of the same year, even if your OPT EAD expired earlier. Your DSO will not issue a new I-20 — your H-1B approval notice (I-797) is your proof of status.
Overview
For F-1 international students, understanding work authorization rules is critical to maintaining lawful status. This guide explains h1b-visa-guide-international-students: who is eligible, how to apply, and what you must do afterward to stay in status.
Eligibility and Key Requirements
To be eligible, F-1 students must maintain valid immigration status throughout the process. This means full-time enrollment, no unauthorized employment history, and SEVIS compliance. Your DSO plays a crucial role in verifying eligibility and initiating work authorization applications.
Application Process and Timelines
The work authorization process involves steps in the correct order. Your DSO recommends you in SEVIS and issues an endorsed I-20. Then compile your application package and submit within the designated window. Track progress through your USCIS online account.
Maintaining Compliance and Reporting
After approval, ongoing compliance is essential. Report address changes within 10 days, stay within authorized hours, and keep your SEVIS record active. For OPT participants, unemployment days count against your authorized period, so track employment status carefully.
Common Mistakes and How to Avoid Them
The most costly mistakes include missing filing deadlines, exceeding unemployment limits, and accepting unauthorized employment. These errors jeopardize your application and F-1 status. Understand rules thoroughly, maintain a compliance calendar, and seek professional guidance.
H-1B is not a guarantee — it is a lottery. Plan for the case where you are not selected, every year.
The H-1B cap, lottery, and registration timeline
The H-1B visa has an annual cap of 65,000 regular visas plus 20,000 reserved for applicants holding a US master’s degree or higher from an accredited US institution. Employers must first register beneficiaries in a pre-lottery registration system, usually in March. USCIS then conducts a randomized lottery to select enough registrations to fill the cap. Selected applicants receive a filing window — typically April to June — during which the employer submits a full petition with supporting documents. The entire process from registration to approval takes four to nine months, and the H-1B start date is October 1 of the same fiscal year at the earliest. If your registration is not selected, you can either use additional OPT time for another lottery attempt, explore cap-exempt H-1B options (universities, nonprofits, government research), or plan alternatives such as O-1, L-1, or day-1 CPT extensions.
Cap-exempt H-1B employers and how they differ
Certain employers are exempt from the H-1B cap: institutions of higher education, nonprofit organizations related to or affiliated with such institutions, nonprofit research organizations, and government research organizations. If you secure a job offer from a cap-exempt employer, there is no lottery — the petition can be filed at any time and approved year-round with an October 1 start date or earlier if amended. Cap-exempt petitions are still adjudicated against the same specialty-occupation criteria as cap-subject petitions, so the role must still meet the degree-and-field nexus test. Many cap-exempt employers also hire on a J-1 or O-1 basis for short-term academic roles. If you later transfer from a cap-exempt H-1B to a cap-subject employer, you may enter the cap-subject pool without being counted against the cap if you have already been counted in a prior H-1B approval — a significant strategic advantage.
Specialty occupation requirements: what the job must meet
For a position to qualify as a specialty occupation, the role must require the theoretical and practical application of a body of specialized knowledge and at least a bachelor’s degree in a specific field (or its equivalent). USCIS examines four criteria: (1) the entry-level requirement for the position in the industry is a bachelor’s or higher; (2) the employer typically requires a degree for similar positions; (3) the duties are so specialized that the knowledge needed is associated with a specific degree; or (4) the position is so complex or unique that the degree requirement is necessary. If the job description is generic — “will perform administrative tasks, data entry, and light analysis” — the petition is at risk of RFE or denial. The best practice is to write detailed, degree-specific duties (e.g., “will design statistical models using Python and R for A/B testing, requiring a degree in statistics or computer science”) that make the degree requirement clear on the face of the job description.
H-1B transfer, amendment, and what happens during a layoff
You can transfer your H-1B to a new employer through a new petition (H-1B transfer) without being re-entered in the lottery, as long as you have already been counted against the cap. You may start working for the new employer once the transfer petition is receipted by USCIS — you do not need to wait for approval. If your H-1B employer terminates your employment, you generally enter a 60-day grace period (or until your I-94 expiry, whichever is shorter) to find a new H-1B employer, file a change of status to another nonimmigrant category, or depart the US. If your employer files a material change amendment (new location, new duties, new corporate entity) and fails to file, you may be considered out of status retroactively. Keep copies of every I-797 approval notice and notify your DSO or immigration counsel within days of any job change or loss.

Frequently asked questions
What is the difference between CPT and OPT?+
CPT is authorized by your DSO during your program. OPT requires a USCIS application and is primarily for after degree completion.
Can I work for multiple employers on OPT?+
Yes, as long as all employment is related to your field of study. Report all employers to your DSO.
What happens if I exceed the 90-day unemployment limit?+
Exceeding the limit terminates your OPT and F-1 status. Track unemployment days carefully and report all employment promptly.
