美国国土安全部 美国公民及移民服务局 www.uscis.gov 美国公民及移民服务局局长办公室 马里兰州斯普林斯营 20588-0009 PA-2026-06 2026年8月5日 政策提醒 主题：在发出补充证据请求时建议进行DNA检测 目的 美国公民及移民服务局（USCIS）正在《USCIS政策手册》中发布政策指南，要求官员在初级证据不可获得、不可靠或不足以证明所声称的遗传关系的情况下，且官员确定需要补充证据时，建议将脱氧核糖核酸（DNA）检测作为证明所声称的遗传关系的一种可选证据形式。
U.S. Department of Homeland Security U.S. Citizenship and Immigration Services www.uscis.gov U.S. Citizenship and Immigration Services Office of the Director Camp Springs, MD 20588-0009 PA- 2026-06 August 5, 2026 Policy Alert SUBJECT: Suggesting DNA Testing When Issuing a Request for Additional Evidence Purpose U.S. Citizenship and Immigration Services (USCIS) is issuing policy guidance in the USCIS Policy Manual to require officers to suggest Deoxyribonucleic Acid (DNA) testing as an optional form of evidence to establish a claimed genetic relationship in cases where primary evidence is unavailable, unreliable, or insufficient to establish a claimed genetic relationship, in situations where an officer determines additional evidence is necessary.
背景 USCIS就受益申请请求、审查证据以确定资格。每项受益申请均有特定的资格要求，申请人必须满足这些要求才能证明所寻求的受益应予批准。1 一般而言，受益申请必须提交初级证据以证明有资格获得所寻求的受益。2 在所需初级证据不存在或无法获得的情况下，申请人必须提供次级证据。3 某些移民受益申请要求受益申请人提交初级证据，以证明所声称的合格遗传关系的存在。此前的USCIS政策指出，官员可以在初级证据和次级证据均被认定不足以证明所声称的遗传关系之后，建议使用DNA证据。此指南导致各业务司对建议使用DNA证据（如有的话）采取不同的指导方针。
Background USCIS requests and reviews evidence in connection with a benefit request to determine eligibility. Each benefit request has specific eligibility requirements that a requestor must meet to demonstrate the benefit sought should be approved.1 In general, benefit requests must be filed with primary evidence to demonstrate eligibility for the benefit sought.2 In cases where required primary evidence does not exist or cannot be obtained, requestors must provide secondary evidence.3 Certain immigration benefit requests require the benefit requestor to submit primary evidence to demonstrate the existence of a claimed qualifying genetic relationship. Previous USCIS policy indicated that officers may suggest DNA evidence after both primary and secondary evidence are deemed insufficient to establish the claimed genetic relationship. This guidance resulted in each directorate having varying guidance on suggesting DNA evidence, if at all.
这项新指南要求官员在受益申请人未能履行其证明所声称遗传关系的举证责任且需要补充证据时，建议使用DNA证据。该新政策也符合第14165号行政命令《保障我们的边境》第九节的规定，该命令指示国土安全部“利用任何可用的技术和程序来确定所声称的家庭关系的有效性”。4 1 见8 CFR 103.2(b)(1)。
This new guidance requires officers to suggest DNA evidence when a benefit requestor does not meet their burden to establish a claimed genetic relationship and additional evidence is needed. The new policy also aligns with section nine of Executive Order 14165, Securing Our Borders, which directs the Department of Homeland Security to utilize “any available technologies and procedures to determine the validity of any claimed familial relationship.”4 1 See 8 CFR 103.2(b)(1).
2 见8 CFR 103.2(b)(1)。
2 See 8 CFR 103.2(b)(1).
3 见8 CFR 103.2(b)。
3 See 8 CFR 103.2(b).
4 见第14165号行政命令《保障我们的边境》，90 FR 8467（2025年1月20日）。
