A chest X-ray for a U.S. immigration medical exam is not a routine part of the process for everyone—it is a follow-up step triggered by specific results from your initial tuberculosis (TB) screening. The initial screening, which is mandatory for all applicants aged 2 and older, typically involves an Interferon Gamma Release Assay (IGRA) blood test (such as QuantiFERON-TB Gold) or, less commonly, a tuberculin skin test (TST). The chest X-ray is only required if your initial screening test comes back positive, if you have signs or symptoms of TB, or if you have certain risk factors like immunosuppression. For applicants aged 15 and older undergoing consular processing overseas, a chest X-ray is often mandatory as the primary screening method. This guide explains exactly when and why you need this X-ray, how the process works, what it costs, and what the results mean for your green card or visa application.
Key Rule: A chest X-ray is not required for everyone. It is mandatory only if your initial TB screening test (IGRA or TST) is positive, if you have TB symptoms, or if you are immunosuppressed. For consular processing, applicants aged 15 and older typically undergo a chest X-ray as the initial screening. The civil surgeon cannot perform a chest X-ray without first conducting an initial screening test, unless a valid exception applies.
When Is a Chest X-Ray Required for Your Immigration Medical Exam?
The requirement for a chest X-ray depends on your age, your initial screening results, and the location of your application (inside the U.S. vs. abroad). The rules are specific and non-negotiable.
For adjustment of status (Form I-693) inside the U.S.:
- Applicants aged 2 and older must undergo an initial TB screening test—either an IGRA blood test or a TST skin test.
- A chest X-ray is required if:
- The IGRA test is positive.
- The TST reaction is 5mm or greater of induration.
- You were not required to take the initial screening test due to a valid exception.
- You have signs or symptoms of TB, regardless of the initial test result.
- You are immunosuppressed (e.g., HIV-positive), regardless of the initial test result.
- For children under 2 years of age, the civil surgeon follows special Technical Instructions.
For consular processing (visa physical) outside the U.S.:
- Applicants aged 15 and older are generally required to undergo a chest X-ray as part of the initial screening.
- Younger applicants may be screened with an IGRA test or TST, with a chest X-ray following if results are positive.
Step-by-Step Process for Getting Your Chest X-Ray
The chest X-ray is integrated into your immigration medical exam workflow. Here is exactly what to expect:
- Complete the initial TB screening test – The civil surgeon will perform either an IGRA blood test or a TST skin test as the first step.
- Receive your test results – IGRA blood test results typically take 2 to 5 business days. TST results are read 48 to 72 hours after placement.
- If the test is positive – The civil surgeon will order a chest X-ray to determine whether you have latent TB infection (LTBI) or active TB disease.
- Undergo the chest X-ray – The X-ray is typically performed at a radiology facility affiliated with the civil surgeon's office or at a designated imaging center. The civil surgeon cannot perform the X-ray without a valid initial screening test result or a documented exception.
- X-ray interpretation – The X-ray must be interpreted by a radiologist or physician trained in reading chest radiographs for TB and lung diseases. The full and formal report must be signed on official letterhead.
- Civil surgeon reviews the report – The civil surgeon will review the X-ray findings and determine your TB classification (Class A or Class B).
- If the X-ray is normal – You are diagnosed with latent TB infection (LTBI) (Class B). The civil surgeon can immediately sign your Form I-693 and provide it in a sealed envelope.
- If the X-ray is abnormal – Further evaluation (such as sputum tests) may be required to rule out active TB. If active TB is confirmed (Class A), you must complete treatment before the civil surgeon can sign your Form I-693.
Costs and Fees for the Chest X-Ray
The cost of the chest X-ray is typically not included in the civil surgeon's base exam fee. It is an additional charge, and the price varies significantly depending on your location and the facility performing the X-ray.
| Cost Component | Estimated Range | Notes |
|---|---|---|
| Civil surgeon exam fee | $200 – $500 | Base fee; varies by location |
| Chest X-ray (additional) | $50 – $200+ | Typically billed separately by the imaging facility |
| IGRA blood test | $100 – $190 | Often included in the exam fee, but may be billed separately |
| Total realistic cost | $300 – $800+ | Includes exam, tests, and any required vaccines |
For consular processing abroad, the cost of the chest X-ray is typically bundled into the panel physician's total exam fee, which can vary widely by country.
When scheduling your exam, ask the civil surgeon's office for a complete cost estimate that includes the base exam, the IGRA blood test, the chest X-ray (if needed), and any vaccines you may require. Some clinics offer package pricing that includes all components.
What Happens If Your Chest X-Ray Is Abnormal or Positive?
A positive or abnormal chest X-ray does not mean your green card or visa application is automatically denied. It simply triggers a more detailed evaluation to determine whether you have active, contagious TB or latent TB infection.
Scenario 1: Positive IGRA / TST + Normal Chest X‑Ray
- You are diagnosed with Latent TB Infection (LTBI) (Class B condition).
- You are not contagious and not inadmissible.
- The civil surgeon can immediately sign your Form I-693 and provide it in a sealed envelope.
- The civil surgeon may recommend that you visit the local health department for further assessment and preventive treatment, but this is not required for USCIS clearance.
Scenario 2: Positive IGRA / TST + Abnormal Chest X‑Ray Suggestive of TB
- Further evaluation is required, typically including sputum smear and culture tests.
- If sputum tests are negative, you are classified as Class B1 (active, non-infectious) and are generally admissible.
- If sputum tests are positive, you are diagnosed with active TB disease (Class A condition).
- Active TB is a Class A condition that renders you inadmissible.
- You must complete treatment (typically 6 months) before the civil surgeon can sign your Form I-693.
- Once treatment is completed and you are cleared, the civil surgeon can complete and sign your form.
If you are diagnosed with active TB, do not panic. This is a treatable condition, and thousands of immigrants successfully complete treatment and receive their green cards every year. Work closely with your civil surgeon and local health department to complete the required treatment and documentation.
Special Considerations: Pregnancy and Immunosuppression
Pregnancy: If you are pregnant and your initial TB screening test is positive, you are still required to undergo a chest X-ray. You may choose to defer the X-ray until later in pregnancy or after delivery, but the civil surgeon cannot sign Form I-693 until the X-ray is performed and interpreted. If you proceed with the X-ray while pregnant, the facility will provide abdominal and pelvic shielding (double-layer, wrap-around lead shields) to protect the fetus.
Immunosuppression: If you are immunosuppressed (for example, due to HIV or certain medications), you are required to undergo a chest X-ray regardless of your initial TB screening result. This is because immunosuppressed individuals are at higher risk of developing active TB.
Common Mistakes to Avoid
Avoid these common errors that can delay your medical exam and green card application:
- Getting a chest X-ray without a referral. The X-ray must be ordered by the USCIS-designated civil surgeon (or panel physician) as part of the official exam process. An X-ray from an outside facility without the civil surgeon's referral will not be accepted.
- Skipping the initial screening test. The civil surgeon cannot perform a chest X-ray without first conducting an initial TB screening test (IGRA or TST), unless a valid exception applies.
- Assuming a positive test means denial. A positive IGRA or TST is common and does not mean you are inadmissible. It simply means you need a chest X-ray to determine whether you have latent or active TB.
- Not bringing your vaccination records. While not directly related to the chest X-ray, missing vaccination records can delay your exam and add unnecessary costs.
- Opening the sealed envelope. Once the civil surgeon completes your Form I-693, it is placed in a sealed envelope. Do not open it (unless filing online, in which case you must open it to upload the form).
- Delaying the X-ray if you are pregnant. While you can defer the X-ray, this will delay your entire application. Discuss the risks and options with your civil surgeon and obstetrician.
Frequently Asked Questions
Q: Is a chest X-ray required for everyone who takes the immigration medical exam?
A: No. For adjustment of status (I-693) inside the U.S., a chest X-ray is only required if your initial TB screening test (IGRA or TST) is positive, or if you have TB symptoms or are immunosuppressed. For consular processing abroad, applicants aged 15 and older typically undergo a chest X-ray as the initial screening.
Q: Do I need to fast before the chest X-ray?
A: No. Fasting is not required for a chest X-ray. You can eat and drink normally before the procedure.
Q: How long does it take to get the chest X-ray results?
A: The X-ray itself takes only a few minutes. The radiologist's report is typically available within 1 to 3 business days. The civil surgeon will review the report and complete your Form I-693 once all results are available.
Q: What if my chest X-ray shows scarring or old TB?
A: Old, healed TB (scarring) is common and does not make you inadmissible. The civil surgeon will classify this as a Class B condition (latent TB) and can sign your Form I-693 immediately. You may be referred for preventive treatment, but it is not required for USCIS clearance.
Q: Can I get a chest X-ray at my own doctor's office?
A: No. The chest X-ray must be ordered by and coordinated through the USCIS-designated civil surgeon (for I-693) or the panel physician (for consular processing). An X-ray from an outside provider will not be accepted unless the civil surgeon specifically refers you to that facility.
Q: What happens if I am diagnosed with active TB?
A: Active TB is a Class A condition that makes you inadmissible. You must complete treatment (typically 6 months) before the civil surgeon can sign your Form I-693. Once treatment is completed and you are cleared, your application can proceed.
Q: Is the chest X-ray report still required to be submitted with Form I-693?
A: No. As of 2013, the chest X-ray report is no longer required to be submitted with Form I-693. The civil surgeon records the findings directly on the form. However, the X-ray must still be performed and interpreted by a qualified radiologist.
