Where can I find DHS or Department of State official tables for immigration statistics 2021–2024?

1. Where DHS publishes its canonical tables — the Yearbook and OHSS portal

DHS’s Office of Homeland Security Statistics (OHSS) is the Department’s central statistical office and the primary place to download comprehensive tables: the Yearbook of Immigration Statistics (individual year pages including 2021, 2022, 2023 and 2024) and other annual flow reports are on OHSS’s Yearbook topic page ^{[1] [2]}. OHSS explicitly describes the Yearbook as “a collection of tables about lawful immigration (green cards, etc.) and immigration enforcement (deportations)” and maintains historical year pages and downloadable tables ^{[2] [6]}.

2. Monthly enforcement and legal-process tables — new regular release from OHSS

For month-by-month enforcement metrics (encounters, arrests, book‑ins, removals, credible‑fear referrals, parole, etc.), OHSS now publishes "Immigration Enforcement and Legal Processes Monthly Tables." OHSS public pages describe these monthly tables as standardized, validated, and covering CBP, ICE, and USCIS components, and note that data come from the OHSS Persist Dataset ^[3]. OHSS announced the first monthly tables release in January 2024, which covered data through September 2023 ^[7].

3. Component agencies: CBP, ICE, USCIS links and component-specific tables

OHSS links to component reports and notes each DHS immigration component collects and publishes its own statistics — CBP (encounters/encounter counts), ICE (ERO removals and interior enforcement), and USCIS (adjustments, naturalizations, processing metrics) — and OHSS pages aggregate or point to those sources ^{[8] [9] [10]}. For USCIS operational tables (naturalizations, adjustments, pending cases), see USCIS’s "Immigration and Citizenship Data" pages; USCIS also posts naturalization totals (e.g., 818,500 new citizens in FY2024 on USCIS pages) ^{[11] [10]}.

4. Department of State visa statistics and the Visa Office report

Visa issuance and consular‑level statistics come from the Department of State (Visa Office). The State Department’s "Report of the Visa Office" (annual visa statistics, e.g., 2021–2024 reports) is hosted on travel.state.gov under Visa Statistics and is explicitly cited as the official source for immigrant and nonimmigrant visa issuances ^[5]. OHSS Yearbook tables sometimes draw on DOS data for refugee or admissions counts ^[4].

5. Topic‑specific OHSS reports and data portals (refugees, adjustments, state data)

OHSS also issues topic‑specific reports: Refugees Annual Flow Reports (e.g., FY‑24 Refugees flow report) and quarterly "Legal Immigration and Adjustment of Status" reports through 2024; OHSS publishes state‑level data sheets with multi‑year counts of LPR arrivals, naturalizations, I‑94 arrivals, and asylum grants ^{[4] [12] [13]}. These are useful when you need finer geographic breakdowns or admission‑class detail ^{[13] [12]}.

6. Practical navigation and downloads: where to click and what to expect

Start at the OHSS landing pages (Yearbook / Immigration topic / monthly tables), then open the specific year (Yearbook 2021–2024) or the monthly tables page to download Excel/CSV tables; OHSS emphasizes tables are produced as data become final and that some tables are updated iteratively ^{[1] [3] [14]}. For visa counts by consulate and visa class, go to DOS’s Visa Office "Report of the Visa Office" page on travel.state.gov ^[5]. USCIS reports and datasets are available from USCIS’s "Immigration and Citizenship Data" toolbox pages ^[10].

7. Caveats, timing, and comparability across sources

OHSS warns that component reporting methodologies and as‑of dates can differ — component tables may not match OHSS standardized tables because OHSS converts component data to common standards and the Persist Dataset is the OHSS system of record ^[3]. OHSS releases provisional monthly tables and then finalizes annual Yearbook tables once all component inputs are finalized ^{[7] [14]}. For refugee ceilings and DOS-based counts, OHSS and DOS may both be cited; check which dataset and fiscal year a table uses ^{[4] [5]}.

8. If you need consolidated third‑party portals or synthesized dashboards

Several think tanks and advocacy groups compile government data into single portals (example: the Center for Immigration Studies Data Portal or Migration Policy Institute summaries), which can be faster for comparative or historical queries — but the original DHS and DOS tables remain the authoritative official sources and should be used when precision or original methodology matters ^{[15] [16]}.

If you want, I can:

• Provide direct OHSS and DOS URLs for the specific Yearbook pages (2021–2024) and the monthly table download page listed in the search snippets ^{[1] [2] [3] [5]}, or
• Pull specific tables (e.g., FY2021–FY2024 total encounters, removals, LPRs) and list the exact filenames and table numbers referenced on the OHSS Yearbook pages ^{[1] [2]}.
