How to Get Visa Sponsorship in Janitor
Confirm the role falls within your OPT authorization
Janitorial work is generally classified under building and grounds cleaning occupations. Verify your OPT employment authorization covers this category and that your job offer aligns with the work type listed on your EAD before starting.
Report your employer to your DSO immediately after accepting
You must report any new job to your Designated School Official within ten days of starting. Provide the employer name, address, and job title to keep your SEVIS record current and maintain valid F-1 status.
Understand the 90-day unemployment limit
OPT students may not accumulate more than 90 days of unemployment during their authorization period. If you are between janitorial positions, track your gap days carefully and prioritize securing your next role quickly.
Target employers with consistent facility needs
Large employers such as hospitals, universities, and commercial property management companies tend to have ongoing custodial staffing needs. These organizations are more likely to offer stable hours and longer-term positions suited to your OPT window.
Clarify full-time versus part-time requirements with your school
OPT requires you to work at least 20 hours per week to maintain valid status. Confirm your janitorial position meets this threshold, especially for roles offered as seasonal, on-call, or variable-hour contracts.

Get Access To All JobsFrequently Asked Questions
Can F-1 OPT students legally work as janitors in the United States?
Yes. F-1 students on post-completion OPT can work in janitorial and custodial roles as long as the position is related to their field of study or qualifies under their authorized employment category. You must have a valid EAD before starting work, and the job must meet the minimum 20-hours-per-week threshold to count toward your OPT period.
Do janitor jobs qualify for STEM OPT extension?
No. Janitorial and custodial occupations are not classified as STEM fields, so they do not qualify for the 24-month STEM OPT extension. Students in this role are limited to the standard 12-month OPT authorization period. If extending your time in the U.S. is a priority, you would need to transition to a qualifying visa category before your OPT expires.
How do I find janitor jobs that are open to OPT students?
Browse Migrate Mate to find janitorial and facilities maintenance positions posted by employers familiar with OPT work authorization. Many employers in healthcare, education, and commercial real estate regularly hire custodial staff and are accustomed to working with candidates who hold EADs. Filtering by employment type and authorization on Migrate Mate helps narrow results to roles suited to your status.
Does my degree field need to match a janitor job for OPT eligibility?
USCIS requires OPT employment to be directly related to your major field of study. Janitorial work may qualify for students with degrees in facilities management, environmental services, or related areas. If your degree is in an unrelated field, consult your DSO before accepting the position, as a mismatch could jeopardize your OPT status and future immigration applications.
What happens to my OPT if my janitorial job ends before my EAD expires?
You can remain on OPT and look for a new position, but you may not accumulate more than 90 days of unemployment during your authorization period. Each day without qualifying employment counts toward that limit. Start your job search immediately after your position ends, track your gap days carefully, and notify your DSO of any change in employment status within ten days.
