The Eleventh Circuit has found that federal courts lack jursidiction to review USCIS’s policy of deferring adjudication of an adjustment of application when the underlying visa category has retrogressed. “We conclude that the challenged USCIS action here—delaying the grant of Form I-485 applications when the Department of State indicates that annual visa limits have been reached—falls within § 1255(a)’s statutory grant of discretion. And challenges to that delay are barred by § 1252(a)(2)(B)(ii).”
