For most U.S. immigrant visa and Green Card applicants, completing the required vaccination schedule is a straightforward part of the medical exam. However, for a small number of individuals, receiving certain vaccines is not possible—either due to a genuine medical contraindication or because vaccination conflicts with sincerely held religious beliefs or moral convictions. In these cases, U.S. immigration law provides a pathway forward through a vaccine waiver. Understanding the difference between a blanket waiver (which requires no separate application) and an individual waiver (which requires filing Form I-601) is essential to avoiding unnecessary delays, additional costs, or a denial of your case. This guide explains the full vaccine waiver process for religious or medical exemptions, including who qualifies, how to apply, and what evidence you need to submit.
Key Rule: There are three types of vaccine waivers: (1) a blanket waiver for missing documentation after receiving the vaccine, (2) a blanket waiver when a vaccine is not medically appropriate, and (3) an individual waiver for religious or moral objections—which must be filed on Form I-601 with the required fee. Medical exemptions are generally handled automatically by the civil surgeon; religious or moral objections require a separate, formal application.
Types of Vaccine Waivers: Blanket Waivers vs. Individual Waivers
Not all vaccine exemptions require you to file paperwork with USCIS. In fact, the two most common scenarios are handled automatically by the civil surgeon or panel physician, requiring no separate form or fee from you.
Blanket waivers are granted by USCIS without a formal application when certain conditions are met. There are two types:
- Missing documentation waiver: If you received a required vaccine but simply lack the paperwork, you can return to the civil surgeon to have the record properly documented. Once the missing vaccine is confirmed, the officer will deem the waiver granted—no form or fee is needed.
- Medical appropriateness waiver: If the civil surgeon certifies that a vaccine is not medically appropriate for you, USCIS grants a blanket waiver automatically. The civil surgeon simply checks the appropriate box on Form I-693, and you are done. No separate filing is required.
An individual waiver is required only when you object to vaccination based on religious beliefs or moral convictions. This type of waiver is not automatic—you must file Form I-601, Application for Waiver of Grounds of Inadmissibility, and pay the required fee.
Medical Exemptions: When a Vaccine Is "Not Medically Appropriate"
Under CDC and USCIS guidelines, a vaccine is considered "not medically appropriate" in four specific situations. In each case, the civil surgeon or panel physician documents the finding on your medical exam form, and USCIS grants a blanket waiver automatically.
| Medical Reason | Explanation | Examples |
|---|---|---|
| Not age appropriate | The vaccine is not required for your age group at the time of the exam | Rotavirus vaccine for an adult; Pneumococcal vaccine for a healthy 30-year-old |
| Contraindication | A condition that would likely cause a life-threatening problem if the vaccine is given | Severe allergic reaction to a previous dose; pregnancy for live vaccines (MMR, Varicella) |
| Insufficient time interval | There is not enough time to complete the required vaccine series before the exam | Hepatitis B series requires 6 months; you only have 2 months before filing |
| Not flu season | The influenza vaccine is only required if the exam occurs during flu season (Sept 1 – Mar 31) | Exam in July—flu vaccine is not medically appropriate |
If any of these apply to you, the civil surgeon will mark the appropriate box on Part 10 of Form I-693. USCIS will then waive that specific vaccine, and you do not need to file any separate form or pay any additional fee.
Religious and Moral Exemptions: The Form I-601 Waiver Process
If your objection to vaccination is based on religious beliefs or moral convictions, you are not eligible for a blanket waiver. Instead, you must file Form I-601, Application for Waiver of Grounds of Inadmissibility. This is a formal application that requires you to prove your eligibility and convince USCIS to exercise discretion in your favor.
To qualify for a religious or moral waiver, you must meet all three of the following criteria:
- You are opposed to vaccinations in any form. The objection cannot be limited to one specific vaccine—you must object to all vaccines. If you object only to the flu shot or only to the COVID-19 vaccine, you generally do not qualify for this waiver.
- The objection is based on religious belief or moral conviction. Your opposition must stem from sincerely held religious or moral principles, not from personal preference, convenience, or general skepticism about vaccines.
- The religious belief or moral conviction is sincere. USCIS evaluates the genuineness of your beliefs based on the evidence you submit. A mere assertion of belief is not enough—you must provide supporting documentation.
The waiver is discretionary, meaning that even if you meet all three criteria, USCIS may still deny the waiver if the negative factors in your case outweigh the positive ones.
Step-by-Step: How to File a Religious or Moral Vaccine Waiver
If you are pursuing a religious or moral exemption, follow this step-by-step process to ensure your application is complete and properly filed.
- Complete your immigration medical exam. You must first be found inadmissible for failing to meet the vaccination requirement. The civil surgeon will document this on your Form I-693.
- Gather supporting evidence. You will need to demonstrate that you are opposed to all vaccinations, that your opposition is based on religious or moral convictions, and that those convictions are sincerely held. Examples of evidence include:
- A personal affidavit explaining your beliefs and why they conflict with vaccination
- Letters from religious leaders or community members attesting to your beliefs
- Documentation showing a consistent history of opposing vaccinations (e.g., school exemption forms, prior statements)
- Religious texts or teachings that support your position
- File Form I-601. Submit the completed application with the required filing fee to the appropriate USCIS lockbox or service center. You must file the waiver while your adjustment of status application (Form I-485) or immigrant visa application is pending.
- Respond to any Requests for Evidence (RFE). USCIS may request additional documentation to verify the sincerity of your beliefs. Respond promptly and thoroughly.
- Wait for USCIS discretion. Even if you meet the eligibility criteria, USCIS must decide whether to grant the waiver as a matter of discretion.
Common Mistakes That Lead to Waiver Denials
USCIS denies many religious and moral vaccine waivers because applicants fail to meet the strict eligibility criteria or do not provide sufficient evidence. Avoid these common pitfalls.
- Objecting to only one vaccine. The waiver requires opposition to all vaccinations. If you object only to the flu shot, the COVID-19 vaccine, or any single vaccine, you do not qualify.
- Failing to demonstrate sincerity. A simple statement that you are religious is not enough. USCIS looks for a consistent pattern of behavior and documentation that supports your claim. If you have previously accepted vaccines without objection, you will need to explain why your beliefs now prevent you from doing so.
- Not providing sufficient evidence. The burden of proof is on you. Vague assertions without supporting documents—such as affidavits, religious texts, or letters from community leaders—are unlikely to succeed.
- Filing too late. You must file Form I-601 while your underlying immigration application (I-485 or immigrant visa) is still pending. Filing after a final denial may not be possible.
- Confusing medical and religious waivers. Medical exemptions are handled by the civil surgeon on Form I-693. Religious and moral waivers require Form I-601. Filing the wrong form or failing to file at all will result in a denial.
Frequently Asked Questions
Q: What is the difference between a vaccine waiver and a vaccine exemption?
A: The terms are often used interchangeably. A waiver is the official immigration term for excusing the vaccination requirement. A medical exemption is granted automatically by the civil surgeon when a vaccine is not medically appropriate. A religious or moral exemption requires filing Form I-601.
Q: Do I need to file Form I-601 for a medical exemption?
A: No. If the civil surgeon certifies that a vaccine is not medically appropriate for you—due to age, contraindication, insufficient time, or it not being flu season—USCIS grants a blanket waiver automatically. You do not need to file any form or pay any fee.
Q: Can I get a waiver if I object to vaccines for personal or philosophical reasons?
A: No. The waiver is only available for religious beliefs or moral convictions. Personal preference, philosophical objections, or general skepticism about vaccine safety do not qualify.
Q: Do I have to oppose all vaccines to qualify for a religious waiver?
A: Yes. The religious or moral waiver requires that you are opposed to vaccinations in any form. If you object only to certain vaccines, you do not qualify for this waiver.
Q: How long does it take for USCIS to decide on a Form I-601 vaccine waiver?
A: Processing times vary widely depending on the service center and the complexity of your case. Form I-601 typically takes several months to over a year to be adjudicated. Filing a complete application with strong evidence can help avoid delays from Requests for Evidence (RFEs).
Q: Is the COVID-19 vaccine still required for the immigration medical exam in 2026?
A: No. Effective January 22, 2025, USCIS waived the COVID-19 vaccination requirement for adjustment of status applicants. Effective March 11, 2025, the CDC removed the COVID-19 vaccination requirement from its technical instructions for panel physicians. You do not need a waiver for the COVID-19 vaccine in 2026.
Q: Can I appeal if my Form I-601 vaccine waiver is denied?
A: Yes. You can appeal a denial to the Administrative Appeals Office (AAO) by filing Form I-290B, Notice of Appeal or Motion. However, appeals are often difficult to win, and you may want to consult an immigration attorney before filing.
Q: What evidence should I submit with my Form I-601 for a religious waiver?
A: Evidence should demonstrate that you oppose all vaccinations, that your opposition is based on sincerely held religious beliefs or moral convictions, and that you have a consistent history of this opposition. Useful evidence includes personal affidavits, letters from religious leaders, religious texts, school exemption records, and documentation of your consistent refusal of vaccines over time.
