全面收紧、系统升级：2025-2026 美国移民审查新变化全解析
Comprehensive Tightening & System Upgrade: A Full Guide to U.S. Immigration Vetting Changes in 2025–2026

⚡ 一句话核心总结 / TL;DR：
2025–2026 年，USCIS 以国家安全与反欺诈为由，对移民审查进行了全面升级——从"一次性审核"变为"持续性监控"，从"统一标准"变为"国别风险分级"，从"纸面材料"扩展到"社交媒体、资金流、社区访谈"的全维度调查。无论您正在申请 H-1B、NIW国家利益豁免、EB-1A 杰出人才，还是等待 I-485 绿卡身份调整，都必须做到材料真实完整、逻辑自洽，并提前构建完善的"解释体系"。新未名律所（New Weiming Law Group）建议大华府DMV地区的华人申请人尽早咨询靠谱华人移民律师，以有效应对这一轮系统性审查升级。

In 2025–2026, USCIS has rolled out sweeping vetting enhancements under the banners of national security and anti-fraud. Reviews have shifted from one-time adjudication to continuous monitoring, from uniform standards to country-based risk tiering, and from paper-only review to full-spectrum investigation covering social media, finances, and community interviews. Whether you are pursuing an H-1B, NIW, EB-1A, or I-485 Adjustment of Status, your filings must be truthful, complete, and internally consistent. New Weiming Law Group advises applicants in the Washington D.C. / DMV Area to consult an experienced immigration attorney as early as possible.

新未名律所持续跟踪美国移民局（USCIS）最新政策变动。2025–2026 年期间，USCIS 以国家安全（National Security）和反欺诈（Anti-Fraud）为核心理由，推出了一系列强化审查措施。这些变化审查更频繁、范围更广、技术更先进、风险分级更精细化，几乎影响到每一位在美国境内的移民申请人，尤其是美国首都华盛顿地区高校、科研机构和高科技公司中的华人留学生、博士后以及 H-1B/O-1/L-1 持有者。以下我们以 Q&A 形式逐一解读。

New Weiming Law Group closely tracks the latest USCIS policy shifts. Throughout 2025–2026, USCIS has unveiled a series of enhanced vetting measures citing national security and anti-fraud objectives. These changes affect nearly every immigration applicant in the U.S.—especially Chinese students, postdocs, and H-1B/O-1/L-1 holders at universities, research institutions, and tech companies across the Washington D.C. metropolitan area (Maryland & Virginia). Below is a detailed Q&A breakdown.

1. 工卡（EAD）有效期缩短意味着什么？
What Does the Shortened EAD Validity Period Mean?

过去，一次 EAD（Employment Authorization Document）审批通过后，申请人可能数年不再接受重新审查。如今，USCIS 缩短了部分工卡有效期，目的是增加"定期重新检查背景 + 身份"的频率。这意味着即使您已拿到 EAD combo 卡，也需要更频繁地面对续期审查——每次续期都相当于一次全新的安全背景核查。

Previously, once an EAD was approved, applicants might go years without further review. Now, USCIS has shortened certain EAD validity periods to increase the frequency of periodic background and identity re-checks. Even if you already hold a valid EAD combo card, you will face renewal reviews more often—and each renewal effectively constitutes a fresh security background check.

2. 身份核查如何变得更严格？
How Has Identity Verification Become Stricter?

USCIS 加强了对护照格式照片重复使用的限制。新申请往往要求申请人重新打指纹（biometrics appointment），或进行生物识别验证（biometric verification），以防止冒用身份。对于正在办理 I-140、I-485、H-1B 转换或 F-1/J-1 身份变更的申请人来说，这意味着额外的时间成本和出行安排。

USCIS has tightened restrictions on the reuse of passport-style photos. New filings increasingly require fresh fingerprinting (biometrics appointments) or biometric verification to prevent identity fraud. For applicants processing I-140, I-485, H-1B transfers, or F-1/J-1 status changes, this translates to additional time costs and scheduling logistics.

3. 审查范围如何从"纸面"扩展到"真实生活行为"？
How Has the Scope of Review Expanded from Paper to Real-Life Behavior?

审查范围的扩大体现在三个维度：

• 社交媒体审查（Social Media Screening）——审查申请人公开社交平台上的言论是否存在安全风险。
• 财务信息审查（Financial Review）——核实资金来源是否合理，是否存在异常大额转账。
• 社区访谈调查（Community Interviews）——调查是否存在虚假婚姻关系或虚假就业安排。

这些维度对婚姻绿卡、EB-2/EB-3 雇主担保（PERM 劳工证）以及 L-1 跨国公司调动申请尤其具有影响。

The expansion manifests in three dimensions: social media screening (checking for security-risk statements), financial review (verifying legitimacy of fund sources), and community interviews (investigating potentially fraudulent marriages or sham employment). These dimensions are particularly impactful for marriage-based green cards, EB-2/EB-3 employer-sponsored cases (PERM Labor Certification), and L-1 intracompany transfer applications.

4. 难民/庇护审查升级（Operation PARRIS）对其他移民类别有何连带影响？
How Does the Asylum Review Upgrade (Operation PARRIS) Affect Other Immigration Categories?

USCIS 针对难民/庇护类别推出了 Operation PARRIS，包括额外背景调查（additional background checks）、再面谈（re-interview）和实质性复审（merit review）。即使已批准或正在等待审理的案件，也可能被重新审查。虽然这一行动主要针对庇护类别，但其所建立的"持续性审查"逻辑和技术基础设施已经开始辐射到职业移民类别（EB 类），包括 NIW国家利益豁免 和 EB-1A 杰出人才案件——尤其在 I-485 阶段。

Under Operation PARRIS, USCIS has introduced additional background checks, re-interviews, and merit reviews for refugee and asylum cases—even previously approved or pending ones. While primarily targeting asylum categories, the "continuous vetting" logic and technical infrastructure are radiating to employment-based categories (EB), including NIW and EB-1A cases—particularly at the I-485 stage.

5. 政府系统联通后，"实时数据更新"会怎样影响申请人？
How Does Real-Time Data Sharing Between Government Agencies Affect Applicants?

移民局（USCIS）、国务院使领馆（DOS）、海关与边境保护局（CBP）等多个政府部门已建立系统联通，实现生物识别自动匹配通知和新犯罪信息自动更新。USCIS 可实时获取申请人最新情况。一旦出现任何新记录——哪怕是轻微违规——都可能影响正在审理或已获批的案件。持有 H-1B、O-1 签证或正在等待 I-140 优先日（Priority Date）排期的申请人务必格外谨慎。

USCIS, the Department of State (DOS), and Customs and Border Protection (CBP) have established system interconnections enabling automated biometric matching alerts and real-time criminal record updates. Any new record—even a minor infraction—may impact pending or already-approved cases. Applicants holding H-1B or O-1 visas, or those waiting for I-140 priority date advancement, must exercise extra caution.

6. 最终审批前增加"最后一轮审查"是怎么回事？
What Is the New "Final Review" Before Approval?

USCIS 现在要求在最终批准前必须完成两项额外核查：

• 逮捕记录审查（Final Arrest Check）——确认申请人在审理期间没有新的逮捕记录。
• 国务院数据库核查（Consular Consolidated Database / CCD Check）——与国务院签证数据库交叉比对。

这意味着即使案件已接近批准，也可能在最后一刻被搁置甚至否决。"最后一刻否决"的可能性明显增加。对于 I-485 身份调整、EB-1A/NIW 批准后的最终绿卡发放，以及 H-1B/L-1 的 I-129 审批，都可能受到影响。

USCIS now requires two additional checks before final approval: a Final Arrest Check (confirming no new arrest records) and a CCD Check (cross-referencing the State Department's visa database). This means cases may be held or denied at the very last moment. The probability of "last-minute denial" has noticeably increased, affecting I-485 AOS, post-approval EB-1A/NIW green card issuance, and H-1B/L-1 I-129 petitions.

7. 内部"冻结与解冻机制"（Hold Mechanism）对审理时间有何影响？
How Does the Internal "Hold & Release" Mechanism Affect Processing Times?

USCIS 已设立内部机制，可以随时暂停（hold）任何案件，然后交由多个部门联合审核后再决定是否恢复处理。这使得案件处理：

• 更不透明——申请人和律师往往无法得知案件被冻结的具体原因。
• 可变性更高——同类案件的处理节奏可能截然不同。
• 审理时间更不确定——无法依赖历史数据预估时间线。

USCIS has established an internal mechanism to place a hold on any case at any time, then subject it to multi-departmental joint review before deciding whether to resume processing. This makes adjudication less transparent (applicants and attorneys often cannot learn the specific reason for a hold), more variable (similar cases may follow entirely different timelines), and less predictable (historical processing data becomes unreliable).

8. "按国家风险分级审查"对中国大陆申请人意味着什么？
What Does Country-Based Risk Tiering Mean for Applicants from Mainland China?

USCIS 现对不同国家进行风险分析，涵盖欺诈风险、公共安全风险和国家安全风险三个维度。审查已进入"国别差异化时代"：不同国家申请人的审查强度不同、面谈概率不同、收到 RFE（Request for Evidence，补件通知）的概率也不同。对于来自中国大陆的 NIW国家利益豁免、EB-1A 杰出人才、H-1B 以及 F-1 转换身份的申请人，建议做好比以往更充分的材料准备。

USCIS now conducts country-specific risk analyses covering fraud risk, public safety risk, and national security risk. Adjudication has entered an era of "country-differentiated vetting": applicants from different countries face varying scrutiny levels, interview probabilities, and RFE (Request for Evidence) rates. Applicants from mainland China pursuing NIW, EB-1A, H-1B, or F-1 status changes should prepare documentation more thoroughly than ever before.

9. "分层审查系统"（Layered Vetting）和审理官指引升级具体包含哪些内容？
What Does the "Layered Vetting" System and Updated Adjudicator Guidance Include?

USCIS 正在建立多层审查体系（Layered Vetting），包括：

• 分类信息审查（机密 + 非机密）
• 扩展犯罪记录检查（expanded criminal record checks）
• 临时安全审查（ad hoc security checks）

同时，USCIS 向审理官提供了更具体的操作指引：哪些国家要重点面谈、哪些材料可信度低、哪些组织（如 FTO，Foreign Terrorist Organization）需要重点关注。审理更加"精准打击"：高风险群体被重点审查，而低风险群体可能更快通过。

USCIS is building a multi-layered vetting system that includes classified and unclassified information review, expanded criminal record checks, and ad hoc security checks. Additionally, updated adjudicator guidance specifies which countries warrant focused interviews, which documents carry lower credibility, and which organizations (e.g., FTOs) require heightened scrutiny. Adjudication has become more "precision-targeted": higher-risk groups face intensified review, while lower-risk groups may see faster processing.

11. 对申请人的实际建议：如何应对这些变化？
Practical Advice for Applicants: How to Navigate These Changes?

✔ 材料必须真实、完整、逻辑一致 / Filings Must Be Truthful, Complete, and Internally Consistent

• 资金流（fund flow）——每笔大额转账都应有清晰来源说明。
• 工作经历——职位描述、薪资记录、W-2/1099 表格需相互印证。
• 身份状态——确保 F-1/J-1/H-1B 等签证身份在每个时间节点均合法有效。

✔ 避免"灰色操作" / Avoid "Gray Area" Practices

• F-1 身份期间的未授权工作问题（unauthorized employment）。
• 资金解释不清——大额现金存款、第三方代持等。
• 虚假关系或虚假职位——这些在社区访谈中极易暴露。

✔ 做好"被深挖"的准备 / Be Prepared for Deep Investigation

• 审查并清理社交媒体内容（Social Media Audit）。
• 整理资金来源证明链条。
• 核实历史记录的一致性——包括出入境记录、I-94、签证历史。

✔ 提前构建"解释体系" / Build a Proactive Explanation Framework

不是只提交材料，而是要能解释每一个细节。遇到 RFE（补件通知）或 NOID（拒绝意向通知）时，能够迅速提供完整、有说服力的回复。拥有双重意图（Dual Intent）签证如 H-1B 和 L-1 的申请人，也需准备好解释身份规划的合理性。
Don't just submit documents—be able to explain every detail. When an RFE or NOID arrives, respond quickly with a complete, persuasive narrative. Applicants with Dual Intent visas such as H-1B and L-1 should also be prepared to justify their immigration planning rationale.
