Part of our Immigration Law FAQ. This cluster covers the mechanics of employment-based cases beyond the numerical categories already explained — labor certification, changing jobs mid-case, premium processing, and work authorization while a case is pending. For the EB-1 through EB-5 category breakdown itself, see our Green Card Categories, Quotas & Key Definitions FAQ. For specific visa categories, see our H-1B, EB-5, and L-1 pages.
What is PERM labor certification, and why does it matter?
Most EB-2 and EB-3 green card cases require the employer to first obtain a labor certification from the Department of Labor, proving that no able, willing, qualified, and available U.S. worker exists for the position at the prevailing wage, and that hiring the foreign worker will not adversely affect similarly employed U.S. workers (INA § 212(a)(5)(A); 20 C.F.R. Part 656). The employer tests the market through mandatory recruitment steps and, if no qualified U.S. applicant is found, files Form ETA-9089 with DOL. Only after certification is approved can the employer file the I-140 immigrant petition. EB-1 categories (extraordinary ability, outstanding researchers, multinational executives) and the EB-2 National Interest Waiver are exempt from this requirement.
Can I change jobs while my green card case is pending?
Often yes, once you have reached a certain stage. The American Competitiveness in the Twenty-First Century Act added INA § 204(j): if your I-485 adjustment application has been pending 180 days or more and your I-140 petition has been approved, you may move to a new job or employer in the “same or similar” occupational classification without having to restart the green card process. Timing and documentation matter — moving too early, or into a role that isn’t sufficiently similar, can jeopardize the case, so this is worth confirming with your attorney before you give notice.
What is “premium processing,” and which cases qualify?
Premium processing (INA § 286(u)) is a paid expedite option under which USCIS commits to acting on an eligible petition within a fixed period — historically 15 calendar days for most classifications, though Congress and USCIS have expanded it over time to additional employment-based categories, including many I-140 petitions and certain I-539/I-765 cases tied to them. The fee and covered classifications change periodically, so we confirm current eligibility and pricing before filing.
Can I work while my employment-based case is pending?
It depends on your underlying status. Someone in valid H-1B, L-1, E, or O status generally continues working for the sponsoring employer under that status while the green card case proceeds. Once an I-485 adjustment application has been filed, the applicant may separately apply for an Employment Authorization Document — commonly the “(c)(9)” pending-adjustment category — which is not tied to the sponsoring employer. 8 C.F.R. § 274a.12 lists the various EAD categories and the paperwork each requires.
What happens if my H-1B cap-subject registration isn’t selected in the lottery?
If your registration is not selected, you cannot file that year’s H-1B cap petition, and you re-enter your options: reapply the following registration cycle, look for a cap-exempt sponsor (higher-education institutions, nonprofit and governmental research organizations under INA § 214(g)(5)), or consider whether another category — O-1, L-1, E-3 (Australian nationals), TN (Canada/Mexico), or a green card route not tied to H-1B — fits your background. Students on F-1 OPT or STEM OPT extension should also plan around the cap-gap rules that can extend work authorization while a subsequent H-1B petition is pending.

What is a priority date, and when can I file my I-485?
Your priority date is your place in the green card line — for PERM-based cases, the date the labor certification was filed with the Department of Labor; for other petitions, the I-140 filing date. 8 C.F.R. § 204.5(d). The employment-based categories of INA § 203(b) carry annual and per-country limits (INA § 202), and the Department of State’s monthly Visa Bulletin shows which priority dates may proceed. You can file the I-485 when your date is current under the chart USCIS designates for that month — sometimes the earlier “Dates for Filing” chart, which lets you file (and get work and travel documents) before final approval is possible.
What is concurrent filing?
When your priority date is already current, the regulations let you file the I-485 adjustment application together with the employer’s I-140 petition in one package, instead of waiting for the I-140 to be approved first. 8 C.F.R. § 245.2(a)(2)(i)(B). Concurrent filing gets the employment authorization and advance parole clock running months earlier — a meaningful hedge if anything happens to your underlying nonimmigrant status while the case is pending.
Do I need an employer to sponsor me for a green card?
Not always. Two employment-based categories are self-petitioned: EB-1A extraordinary ability (INA § 203(b)(1)(A)) and the EB-2 National Interest Waiver (INA § 203(b)(2)(B)(i), applied under Matter of Dhanasar, 26 I&N Dec. 884 (AAO 2016)). Neither requires a job offer or labor certification. Everyone else in EB-2 and EB-3 needs an employer to run the PERM labor certification process and file the I-140.
What happens to my green card process if I am laid off?
It depends on the stage. A PERM or an unapproved I-140 generally dies with the job. Once the I-140 has been approved for 180 days, the employer’s withdrawal no longer revokes it automatically (8 C.F.R. § 205.1(a)(3)(iii)(C)), and you keep the priority date for a future employer’s petition (8 C.F.R. § 204.5(e)). If your I-485 has been pending 180 days, you may port to a same-or-similar job under INA § 204(j). Nonimmigrant status is the urgent problem — the 60-day grace period of 8 C.F.R. § 214.1(l)(2) starts immediately; see our H-1B layoff options guide.
