How E-Verify works in Maryland
E-Verify is voluntary for private employers in Maryland. No state law requires most businesses to enroll. Federal contractors working on covered contracts, however, must use E-Verify for new hires assigned to that work regardless of what state law says. In practice, this means E-Verify enrollment is especially common among Maryland's large defense contractors, federal agency contractors, and NIH-funded research institutions. For F-1 students pursuing a STEM OPT extension, this matters directly: your employer must be enrolled in E-Verify regardless of state rules. The list below reflects employers who meet that requirement.
Frequently Asked Questions
Does Maryland require employers to use E-Verify?
Maryland doesn't require most private employers to use E-Verify. Enrollment is voluntary unless the employer holds a federal contract covered by the FAR E-Verify clause, which requires E-Verify use for employees assigned to that contract. This means you'll find high E-Verify enrollment among Maryland's large defense and government contractors, particularly in the Baltimore-Washington corridor, but smaller private employers in the state may not be enrolled at all.
Does my employer need to be in E-Verify for my STEM OPT extension?
Yes. Federal rules require your employer to be enrolled in E-Verify before you can qualify for the 24-month STEM OPT extension. This isn't a state requirement or a preference. It's a hard federal condition. If your employer isn't enrolled when you apply for the extension, your DSO can't sign the updated I-20, and USCIS won't approve the extension. Confirm E-Verify enrollment before accepting any job offer you plan to use for a STEM extension.
How do I confirm a Maryland employer is actually enrolled in E-Verify?
Ask your HR contact directly whether the company is enrolled in E-Verify and whether your specific work location is covered. You can also search the E-Verify employer search tool on the DHS website, which lets you look up enrollment by employer name and state. For STEM OPT purposes, your DSO will also verify enrollment before signing your updated I-20. Don't rely on a job posting that mentions E-Verify, since postings sometimes reflect company policy in other states rather than the hiring location.
What happens if I start a job and my employer turns out not to be enrolled in E-Verify?
If you're on initial OPT, you can still work legally. E-Verify enrollment only becomes a hard requirement when you apply for the 24-month STEM OPT extension. If your employer isn't enrolled at that point, you can't get the extension approved. Your options are to ask your employer to enroll, which takes a few days, or find a new employer who is already enrolled.

Do H-1B, TN, or E-3 workers need an E-Verify employer in Maryland?
There's no federal rule requiring your employer to be enrolled in E-Verify specifically because you hold an H-1B, TN, or E-3 visa. E-Verify enrollment doesn't affect your eligibility for those statuses. That said, many of Maryland's largest employers in defense, federal contracting, and healthcare are enrolled anyway due to their contract obligations. For those visa types, E-Verify enrollment is a reasonable indicator that an employer handles employment verification compliance consistently, but it isn't a requirement the way it is for STEM OPT.
