USCIS has been falling farther and farther behind on adjudication of EB-5 filings. Last week USCIS suddenly announced that, starting March 31, 2020, it will adjudicate first I-526 petitions from investors for whom a visa number will be immediately or soon available. The rationale is that investors from visa backlogged countries (mainland China, Vietnam, and India) would not be able to use the I-526 approval if USCIS adjudicated them more quickly, so the agency is allocating resources where they will be more immediately useful.
