Both routes end at the same EB-2 visa queue and differ in everything before it. A PERM is an employer proving to DOL that no U.S. worker was available for a specific job. A national interest waiver is a worker proving to USCIS that their own work matters enough to skip that proof. The person and the job decide which one fits, more than which is faster in the abstract. To see which categories your job points to, answer a few questions in PERM Tracker's free green card chooser, which works from the regulation's own definitions.

	PERM (EB-2 or EB-3)	National interest waiver (EB-2)
Who files	The employer, for a specific job	The worker, for themselves. An employer may also file
Job offer	Required, at the prevailing wage	Waived
Labor certification	Required: DOL's finding that no U.S. worker was available	Waived
Recruitment	The mandatory steps under 20 CFR 656.17, inside 180 days of filing	None
Prevailing wage	A determination before recruitment, valid 90 days or to June 30	None
Standard	The job's minimum requirements against the applicants who came forward	Dhanasar: substantial merit and national importance, well positioned, and on balance better to waive
Category	EB-2 or EB-3, set by the job's requirements	EB-2 only
Changing jobs	The certification is for one job. A new job means a new PERM	The petition is the person's. The endeavor has to continue
DOL's queue	Yes: DOL's published average is 300 days as of October 31, 2026 for an analyst-review decision, plus the wage queue before it	No DOL stage at all
Premium processing	On the I-140 only, after DOL	On the I-140, 45 business days
Who can pay	The employer pays the PERM stage. 20 CFR 656.12 forbids passing it to the worker	The worker may pay everything

What the PERM requires

The employer defines a job and gets a prevailing wage determination for it. Then it advertises the job under the recruitment rules and files the ETA-9089, attesting that no able, willing, qualified and available U.S. worker applied. DOL decides that application in filing order. The certification then supports an I-140 in EB-2 or EB-3. The category depends on what the job requires, and the worker's own qualifications don't decide it.

The wait is the PERM's defining cost. The wage determination has its own queue, and recruitment takes two to six months. After that, DOL's queue is the better part of a year. The green card timeline draws each stage to scale.

What the waiver requires

INA 203(b)(2)(B) lets USCIS waive the job offer and the labor certification when it would be in the national interest. The test is Matter of Dhanasar (2016). It asks whether the proposed endeavor has substantial merit and national importance, and whether the person is well positioned to advance it. It also asks whether, on balance, it would benefit the United States to waive the requirements. Evidence is the person's record: publications, patents, letters from people who know the field, a plan, and proof the plan is underway.

There's no DOL stage. The I-140 is filed directly, with premium processing available, and the priority date is the day USCIS receives it. Everything after the I-140 is the same as a PERM case: the same EB-2 cutoff, the same I-485 or consular process.

Where the two routes converge

The two routes converge on the visa queue, the I-140's rules and the H-1B extensions.

The visa queue. Both are EB-2 for the same country of chargeability, and the cutoff date doesn't care which route set the priority date. The priority date history is the same chart for both.
The I-140's rules. An approved petition from either route retains its priority date under 8 CFR 204.5(e) and gains the 180-day protections. The retention calculator applies to both.
The H-1B extensions. AC21's 106(a) counts a labor certification or an I-140 on file for 365 days. A waiver petition is an I-140, so it qualifies. The six-year limit calculator takes either.

What the record can show

USCIS publishes I-140 receipts, approvals and denials by subtype each quarter, and the waiver has its own line. The I-140 trends page shows how the two compare in volume and outcome over time, with the quarter each figure was published for. It shows rates over populations. It can't predict the outcome for one person.

What this comparison can't tell you

It can't tell you whether your record meets Dhanasar, whether your job puts a PERM in EB-2 or EB-3, or which route is faster for you.

Whether your record meets Dhanasar. That's a judgment about a body of work, and the attorneys who file waivers are the people who can make it.
Whether your job's requirements put a PERM in EB-2 or EB-3. That's on the ETA-9089, and EB-2 vs EB-3 covers the difference.
Which is faster for you. A waiver skips DOL, but a denied waiver has no queue position at all, and the EB-2 cutoff is the wait that dominates either route for an oversubscribed country.
