Petitions USCIS decided for Zefr's H-1B workers, by federal fiscal year (October to September). This is the employer's filing record, separate from what any one posting says.
* Partial year: FY2026 (Oct 1, 2025 – Jun 30, 2026). Drawn lighter because the year is not complete in its source.
| Fiscal year | New employment approved | Continuing approved | Total approved | Denied | Source |
|---|---|---|---|---|---|
| FY2019 | 4 | 2 | 6 | 1 | USCIS yearly file |
| FY2020 | 1 | 1 | 2 | 0 | USCIS yearly file |
| FY2021 | 0 | 4 | 4 | 0 | USCIS yearly file |
| FY2022 | 2 | 6 | 8 | 0 | USCIS yearly file |
| FY2023 | 0 | 3 | 3 | 0 | USCIS hub |
| FY2024 | 1 | 3 | 4 | 0 | USCIS hub |

| FY2026 · partial (Oct 1, 2025 – Jun 30, 2026) | 0 | 2 | 2 | 0 | USCIS hub |
Zefr is below our H-1B filer threshold (at least 10 new-employment approvals in the latest full fiscal year, or at least 25 approvals in FY2026 to date), so its postings don't carry an “H-1B filer” note.
Source: USCIS H-1B Employer Data Hub. Each number counts workers on petitions USCIS decided that year (first decisions only), for the petitioner name ZEFR INC. It counts petitions decided, not job openings, and it does not say whether a particular role will be sponsored. FY2019–FY2022 come from USCIS's yearly files; FY2023 onward from the live hub, which USCIS updates quarterly. Matched on the exact legal name, with one consistent tax ID. Search the USCIS hub
