RIA Section S is an uncodified provision of the EB-5 Reform and Integrity Act of 2022, signed March 15, 2022 as part of H.R. 2471 (117th Cong.). Practitioners commonly refer to it as "Section S" or "Subparagraph S." The provision is statutory rather than regulatory; USCIS has not promulgated implementing regulations addressing the mechanics of grandfathering, though the agency has signaled in informal communications that it will honor the cutoff and continue processing protected petitions.
The text of Section S directs DHS to continue processing I-526E petitions filed before the deadline, plus the downstream I-829 petitions that follow from those timely-filed I-526Es. AILA practitioners (Jennifer Hermansky, Ron Klasko, Carolyn Lee) confirm that the protection extends to pending immigrant-visa applications at the State Department and to concurrent adjustment-of-status (I-485) applications that flow from a timely-filed I-526E. Direct EB-5 (the standalone program) is unaffected by Section S because the standalone program is permanent and not subject to the September 30, 2027 statutory expiration.
There is a one-year disconnect between the grandfathering date (September 30, 2026) and the regional-center program's statutory expiration (September 30, 2027). The reason for the one-year gap is not stated in legislative materials and is, by Carolyn Lee's characterization, unknown. IIUSA is lobbying to synchronize the two dates by extending grandfathering to coincide with program expiration, but as of March 2026, no legislation has advanced.
The inflation adjustment provision, mandated by INA § 203(b)(5)(C), takes effect for the first time on January 1, 2027. The post-RIA investment minimums of $800,000 (TEA) and $1,050,000 (non-TEA) will adjust automatically every five years beginning on that date. Petitions filed before January 1, 2027 are at the current minimums; petitions filed on or after that date will be at the adjusted minimums. The interaction between the September 30, 2026 grandfathering deadline and the January 1, 2027 inflation adjustment creates a three-month window (October 1, 2026 to December 31, 2026) where filings are not grandfathered but are still at current minimums; filings on or after January 1, 2027 are not grandfathered and are at adjusted minimums.
