一、移民体检在哪里做？普通医院可以吗？
Where to Get the Medical Exam? Can I Go to a Regular Hospital?

中文解析：移民体检绝对不能随便找医院。即便您目前持有 F-1 或 H-1B 签证，也不能在校医院或普通家庭医生处体检。必须在 USCIS 指定的移民医生 (Civil Surgeon) 处完成，只有他们有权签署 I-693 表格。您可以通过移民局官网的 "Find a Civil Surgeon" 工具查找。

English Explanation: You cannot go to a random hospital for an immigration medical exam. Even if you are on an F-1 or H-1B visa, school clinics or standard family doctors are not authorized. It must be completed by a USCIS-designated Civil Surgeon. You can find one using the "Find a Civil Surgeon" tool on the USCIS website.

二、体检会检查哪些核心项目？
What Key Health Items Are Tested During the Exam?

• 疫苗记录：必须符合 CDC 要求（MMR、Tdap、水痘、乙肝、流感等），疫苗不全需补打。注意：自2025年底起，COVID-19 疫苗不再是必需项目。
• 传染病筛查：包括结核病 (TB) 测试（阳性需拍胸片）、梅毒检测及淋病检测。
• 身体与精神评估：常规血压心肺检查，以及评估是否存在可能危害他人或社会的精神疾病史。

• Vaccine Records: Must meet CDC guidelines (MMR, Tdap, Varicella, Hepatitis B, Influenza). Missing vaccines must be administered. Note: Starting late 2025, the COVID-19 vaccine is no longer required.
• Communicable Diseases: Includes Tuberculosis (TB) tests (chest X-ray if positive), Syphilis, and Gonorrhea screening.
• Physical & Mental Assessment: Basic vital checks and an evaluation of any mental disorders associated with harmful behavior.

三、去体检需要准备什么材料？费用如何？
What to Bring & How Much Does It Cost?

中文解析：去诊所时请携带护照原件、所有疫苗记录本、既往重大病史资料，如果您之前在做 J-1豁免 时查过相关医疗记录也建议带上。体检没有全美统一价格，通常在 200 到 600 美元范围波动，若需额外抽血查抗体或补打疫苗需另收费。建议打电话货比三家。

English Explanation: Bring your passport, complete vaccination records, and significant medical history documents. Pricing is not standardized across the U.S. and generally ranges from $200 to $600. Additional fees apply for administering missing vaccines or drawing blood for antibody titers. It is highly recommended to call several doctors to compare prices.

四、【2026年最大变革】I-693 必须如何提交？
[2026 Major Change] How Must the I-693 Be Submitted?

中文解析：当您的优先日排到后，递交 I-140/I-485（或单独递交 I-485）时，必须随附 I-693 表格一起提交。体检报告将由医生密封在信封里，您绝不能私自拆封！如果提交包裹中没有附上该体检信封，I-485 会被邮件室直接拒收，不会进入审理阶段。您不能再像过去几年那样先交申请然后干等移民局发 RFE。

English Explanation: Once your priority date is current, your I-485 application must include the I-693 form at the time of filing. The medical report will be given to you in a sealed envelope—do not open it! If filed without it, the I-485 will be rejected at the mailroom outright. You can no longer file merely the application and wait for a Request for Evidence (RFE) to supply the medicals later.

五、【2026年新规】体检的“2年有效期”还有效吗？
[2026 New Rule] Is the "2-Year Validity" Still Applicable?

中文解析：好消息是，“2年有效期”和要求医生签字不超过提交前“60天”的严苛规则都被永久取消了。现在的规则是：I-693 的有效期完全与它所附属的那份 I-485 深度绑定；只要处于 双重意图 Dual Intent 的审理期中，它就一直有效。但需要警惕的是，如果你的这第一份 I-485 被拒、撤回或你换类别重新递交了一份新的 I-485，旧的 I-693 将自动作废，必须重新体检！

English Explanation: The good news is that both the "2-year validity" and the "60-day signature requirement prior to filing" have been permanently eliminated. The I-693's validity is now strictly tied to the specific I-485 application it was filed with. As long as that I-485 is pending, the medical is valid. However, if your I-485 is denied, withdrawn, or if you file a brand new I-485 under a different category, the original I-693 becomes void, and you must undergo a new medical exam!
