What changed
The American Competitiveness in the Twenty-First Century Act of 2000 (AC21), Public Law 106-313, signed October 17, 2000, was the operative response to the multi-year employment-based priority-date backlogs that had begun to emerge in the late 1990s. AC21 created the two procedural mechanisms — H-1B extension beyond the sixth year, and I-485 portability — that today let backlogged beneficiaries live and work in the United States during waits that now exceed a decade for some chargeability areas.
AC21 § 104(c) permits H-1B extensions in three-year increments past the sixth-year statutory cap at INA § 214(g)(4) for an H-1B beneficiary who is the beneficiary of an approved I-140 and who cannot adjust status because of per-country oversubscription. AC21 § 106(a) permits one-year H-1B extensions past the sixth-year cap when 365 days have elapsed since the filing of a PERM or I-140. AC21 § 106(c) — codified at INA § 204(j) — permits the beneficiary of an approved I-140 to “port” the I-485 to a new employer in the same or similar occupation when the I-485 has been pending 180 days.
Child status protection comes from a different statute. The Child Status Protection Act, Public Law 107-208, signed August 6, 2002, added INA § 203(h) to freeze an unmarried child’s age, for derivative-beneficiary purposes, by reference to the time the I-140 was pending. The arithmetic — biological age at visa availability minus time I-140 was pending, with the result locked in if the child “sought to acquire” lawful permanent resident status within one year — drives most child-status-protection planning. The USCIS Policy Manual, Volume 7, Part A, Chapter 7 walks through the CSPA calculation; the Supreme Court’s decision in Scialabba v. Cuellar de Osorio, 573 U.S. 41 (2014), governs aged-out derivative beneficiaries’ eligibility for parents’ later F-2B petitions.
The operative monthly artifact is the Department of State Visa Bulletin. Each bulletin lists, for each employment-based and family-based preference category and each chargeability area, two dates: the “Application Final Action Date” (when visa numbers may be issued / adjustments approved) and the “Dates for Filing Applications” (when applicants may submit adjustment applications). USCIS publishes a monthly notice indicating which of the two charts adjustment applicants may use that month — the “Dates for Filing” chart in some months, the “Final Action” chart in others.
Why it matters
For a U.S.-employer-sponsored Indian or Chinese national in EB-2 or EB-3, the practical operative facts of the current visa-bulletin regime drive every immigration decision they will make over a decade or more.
EB-2 India sits at 2013. The November 2024 Visa Bulletin’s EB-2 India Final Action Date was January 1, 2013; the May 2026 issue’s date varies slightly by month but remains in the same year-band. EB-3 India has been similarly retrogressed, fluctuating with periodic downgrade movement. EB-2 China and EB-3 China are less extreme but still multi-year. EB-2 worldwide and EB-3 worldwide have been current much of the time, but have retrogressed in some months. Filing strategy for an Indian or Chinese beneficiary should assume a multi-year wait between PERM filing and I-485 approval, plan for H-1B extensions in three-year increments throughout, and plan around the children’s CSPA age trajectory.
AC21 § 104(c) is the durable H-1B extension mechanism. Once a beneficiary has an approved I-140 and the per-country backlog precludes adjustment, the beneficiary may extend H-1B in three-year increments indefinitely under § 104(c). The USCIS Policy Manual, Volume 2, Part I, Chapter 5 walks through the I-129 evidence USCIS expects — the approved I-140, evidence of per-country backlog (the DOS Visa Bulletin attachment), and the new employer’s job-offer letter. Some employers prefer one-year § 106(a) extensions for procedural simplicity; the strategic question is whether the beneficiary wants three-year stability or one-year flexibility.
§ 204(j) porting is the off-ramp. A beneficiary with an approved I-140 and a pending I-485 (180 days or more) may take a new job with a new employer in the same or similar occupation. The new employer does not need to file a new I-140. USCIS evaluates the same-or-similar standard using the Standard Occupational Classification (SOC) codes and the duties described in the original PERM. The implementing regulation is at 8 CFR 245.25. Form I-485 Supplement J (Form I-485J) is the operative confirmation document. Practitioners who advise on porting should match the new role’s SOC code and duties to the original PERM closely; mismatches draw RFEs and occasional denials.
CSPA arithmetic is unforgiving. Under INA § 203(h)(1), the child’s “age” for derivative-beneficiary purposes is the child’s biological age at the time a visa number is available, reduced by the time the I-140 was pending. If the result is under 21, the child remains a derivative; if it is 21 or over, the child has aged out. The child must “seek to acquire” lawful permanent resident status within one year of visa availability to lock in the calculated age. USCIS issued an important policy update on February 14, 2023 clarifying that the “visa availability” used in the calculation is the date the visa first becomes available based on whichever chart (Final Action or Dates for Filing) USCIS authorizes for filing in that month — a change that effectively gave many India-EB-2 derivative children a substantially younger CSPA age. The CSPA’s mechanics are notoriously fact-specific; the agency guidance at Volume 7, Part A, Chapter 7 is the operational starting point.
A note on EB-2/EB-3 downgrades. In some Visa Bulletin months, EB-3 India’s Final Action Date runs ahead of EB-2 India’s. Beneficiaries whose PERMs support both classifications have downgraded by filing concurrent EB-3 I-140s and amended I-485s. The downgrade strategy is permitted under 8 CFR 204.5(e) (priority-date retention) and is documented in the USCIS Policy Manual, Volume 6, Part E. When EB-2 again moves ahead of EB-3, beneficiaries upgrade back. Tracking the relative dates is the operational task.
Way forward
For practitioners managing a backlogged employment-based pipeline in 2026:
- Map the AC21 calendar at the outset. For an Indian or Chinese H-1B beneficiary expected to face multi-year retrogression, calendar the PERM-filing date plus one year (the § 106(a) eligibility trigger), the I-140 approval date (the § 104(c) eligibility trigger), and the per-country I-140 backlog status. Brief the employer’s HR / immigration ops team on which extension type they will be filing at each H-1B renewal.
- Calendar the child’s CSPA trajectory. For each derivative child under 21, calculate the I-140-pending offset and the projected age at visa availability. If a child is on track to age out, evaluate alternative pathways early — F-2B chargeability, B-1/B-2 visit during gaps, or independent F-1 status. The USCIS CSPA calculator and policy guidance is the source; the calculation is mechanical but error-prone.
- Use the Dates for Filing chart strategically. When USCIS announces that adjustment applicants may use the Dates for Filing chart for a given month, file I-485s early to obtain EAD and advance parole even though final adjustment will not occur until the Final Action Date catches up. This is materially valuable: EAD detaches the beneficiary’s spouse from H-4 dependency and gives the principal occupational flexibility under § 204(j).
- Port carefully. If using § 204(j) to take a new job, document the new role’s SOC code, duties, and salary. File Form I-485 Supplement J promptly. The same-or-similar standard is forgiving in most cases but tightens for material differences in seniority or occupation.
- Watch for downgrade windows. Subscribe to the DOS Visa Bulletin RSS feed and check the monthly bulletin within 24 hours of publication. When EB-3 India runs materially ahead of EB-2 India, evaluate whether your beneficiary’s PERM supports an EB-3 downgrade filing.
- Brief clients on the timeline candidly. Indian and Chinese EB-2 and EB-3 beneficiaries are committing a decade or more of their working lives to this process. Front-load the conversation about what that means — children’s CSPA risk, job-change constraints, the H-4 spouse’s EAD pathway, the practical equivalence of an approved I-140 with no visa number. Expectation management is the single highest-leverage thing a practitioner does in this space.

Visa retrogression management is fact-intensive and turns heavily on the beneficiary’s chargeability area, the child’s birth date relative to I-140 filing, the PERM’s SOC code and duties, and the monthly visa-bulletin movement.
