Avoid I-693 Delays: 3 TB Records for Applicants With Prior TB
If you have verifiable records showing you completed TB or LTBI treatment, and your current chest x-ray is normal with no symptoms, the civil surgeon can usually complete Form I-693 as “No Class A or Class B TB.” The three items that decide this outcome: signed IGRA or TST reports, your prior chest x-ray image or report, and documentation showing you finished treatment. Show up without them, or with an abnormal chest x-ray, and you’re looking at a mandatory referral to the local health department that can stall your case for weeks.
TL;DR:
- Proper documentation of prior TB treatment, including signed lab reports, chest x-ray images, and treatment records, prevents delays and referral to health authorities.
- A current positive TB test or abnormal chest x-ray prompts a referral to the local health department, which can extend processing times by weeks.
- Missing or incomplete records often cause RFEs or delays; requesting and reviewing records before the exam can streamline the process.
- IGRA tests like QuantiFERON or T-Spot are now preferred over TST due to faster results and no need for a return visit, especially if prior TB records are available.
- A straightforward case with documented treatment and a normal current chest x-ray usually results in an uncomplicated “No Class A or Class B TB” outcome, with no further TB actions needed.

Previous TB History on I-693: What USCIS and the CDC Require
Every applicant age 2 and older must undergo an initial TB screening as part of the immigration medical exam, using either an IGRA blood test or a TST skin test. This isn’t optional, and it isn’t something a civil surgeon can waive on their own judgment. The rules come from the CDC Technical Instructions for Civil Surgeons, and every USCIS-designated civil surgeon in the country works under them.
For applicants with a previous TB infection form or history of treated TB, the screening rules don’t disappear. They just interact differently with your paperwork. If you already have a documented prior positive IGRA or TST, you generally don’t repeat that same test; the civil surgeon shifts focus to a chest x-ray and a symptom review instead. There’s one narrow carve-out: applicants with a documented history of a severe reaction to a prior TST may be screened differently to avoid triggering another reaction.
Chest x-ray becomes mandatory once you’re 2 or older and either test positive for TB infection or already carry a diagnosis of prior TB disease. The civil surgeon reads the film against a specific set of criteria. Most old, calcified scarring passes without issue. Anything that looks active does not.
Here’s what determines whether your exam proceeds smoothly or gets kicked to a referral:
- A negative or appropriately explained TB test plus a clear chest x-ray usually clears you the same day.
- A positive TB test with a normal current chest x-ray, combined with documented completed treatment, typically supports a “No Class A or Class B TB” finding.
- A chest x-ray suggestive of active disease triggers automatic referral to the local health department, regardless of how the TB test came back.
- Symptoms consistent with active TB (persistent cough, unexplained weight loss, night sweats) can trigger further workup even with a clean x-ray.
The civil surgeon’s job is essentially detective work: piece together your test history, your imaging, and your treatment records into a picture that matches CDC classification criteria. Missing pieces don’t get guessed at. They get investigated, and that investigation takes time.
Documents to Bring for a Prior TB Diagnosis or LTBI
This is the part most applicants underestimate. A verbal statement of “I took medication for TB in 2019” means nothing to a civil surgeon without paper behind it. The CDC’s own guidance ties classification outcomes directly to documentation quality, and that means the burden of proof sits with you, not the clinic.
Bring these, in this priority order:
- Signed laboratory reports for any IGRA or TST performed previously, showing the test date, the test type (QuantiFERON, T-Spot, or TST), and the numeric or qualitative result. A text message from a doctor’s office confirming “you tested positive” does not meet this bar.
- Prior chest x-ray films or official radiology reports, dated and signed by the facility or radiologist. If you can get the actual image on a disc or through a patient portal, bring that too. A written report alone is useful, but a civil surgeon comparing it against today’s film for signs of stable old scarring versus new findings benefits enormously from the original image.
- Treatment records showing which drugs you took, start and end dates, and a provider or pharmacy signature. Standard LTBI treatment runs through regimens like isoniazid for several months or a shorter rifapentine combination; active TB disease treatment typically runs longer. What matters to the civil surgeon isn’t the specific drug name as much as proof the full course was completed.
- Any discharge summary from a hospital or TB clinic, if your treatment involved inpatient care or public health department supervision.
When original medical records aren’t available, pharmacy dispensing histories and discharge summaries often serve as secondary evidence. Civil surgeons will still typically want a current IGRA and chest x-ray in that scenario, but documented, itemized attempts to secure your original records upfront tend to shorten the review rather than lengthen it.
Pro Tip: Call your former provider’s medical records department before your exam, not after. Most offices take 5 to 10 business days to process a records request, and showing up to your civil surgeon appointment with that paperwork already in hand is the single biggest thing you can do to avoid a second visit.
One more detail people miss: a single calcified nodule on an old chest x-ray is specifically called out in CDC guidance as a finding that does not require referral on its own. If your prior x-ray report already mentions that kind of stable, healed scarring, it’s worth highlighting to the civil surgeon rather than assuming they’ll dig it out of a paragraph of radiology language.
TB Testing and Chest X-Ray During Your Civil Surgeon Visit
IGRA and TST accomplish the same basic goal, screening for TB infection, but they work differently in practice. TST requires a skin injection and a return visit 48 to 72 hours later to read the reaction, which means two appointments. IGRA is a single blood draw, read in a lab, with no return visit required. That’s why IGRA tests like QuantiFERON and T-Spot have become the default at many civil surgeon clinics: applicants get results faster and don’t have to come back.
A chest x-ray isn’t a general health screening. It exists specifically to distinguish active TB disease from old, inactive infection or no infection at all. The findings a radiologist and civil surgeon are hunting for:
- Infiltrates or consolidation suggesting active infection
- Cavitary lesions
- Non-calcified nodules
- Pleural effusion
Findings that typically do not require referral include a single calcified granuloma or stable, longstanding scarring that matches a prior film.
At a typical civil surgeon appointment, the sequence runs: medical history review, IGRA blood draw (results often same-day or next-day depending on the lab), chest x-ray if your history or test results call for one, then a final review once everything is back. Special cases change the sequence slightly. Children under 2 generally aren’t screened with IGRA or TST for I-693 purposes. HIV-positive applicants face closer scrutiny of chest x-ray findings because latent infection is more likely to progress in immunocompromised patients. And anyone with prior treated TB disease needs that treatment documentation squared away before the civil surgeon can finalize a classification, no matter how the current tests come back.
Health Department Referrals: What Triggers Them and How Long They Take
A civil surgeon who sees a chest x-ray suggestive of TB has no discretion here. USCIS policy requires referral to the local health department, and the civil surgeon cannot sign Form I-693 until that health department evaluation is completed and returned to the clinic. This is the single biggest source of unexpected delay for applicants with a history of treated TB.
Findings that commonly trigger this referral, per CDC guidance, include:
- Infiltrates or consolidation
- Cavitary lesions
- Non-calcified nodules
- Pleural effusion
- Any pattern the radiologist flags as indeterminate between old scarring and active disease
Once referred, the local health department typically runs its own evaluation: sputum collection for smear and culture (or a molecular NAT test), a clinical exam, and sometimes a treatment plan if active TB disease is confirmed. If treatment is required, USCIS generally won’t consider the case resolved until that treatment is documented as complete or the applicant is on an approved public health monitoring plan.
Timeline expectations vary widely. Sputum culture results alone can take two to eight weeks depending on the lab and the health department’s workload; a rapid molecular test can return in a day or two. Health departments in high-volume counties tend to move slower simply due to case volume, not any special scrutiny of your file. If you’re already carrying complete records of a past, fully treated TB episode, this whole referral pathway is usually avoidable, since a normal current x-ray with documented past treatment doesn’t hit the referral triggers in the first place.
How the I-693 Form Records TB Findings and What Classifications Mean
Form I-693 captures TB findings across several sections: the medical history review, the physical exam, and a dedicated section for tuberculosis screening results, chest x-ray determination, and any health department referral notes. The I-693 instructions walk civil surgeons through exactly how to annotate each outcome.
The classifications that matter to you:
- No Class A or Class B TB: the most common outcome for applicants with a documented, completed treatment history, a negative current chest x-ray, no symptoms, and no known HIV infection. This clears you with no further TB-related action needed.
- Class B1 or B2 TB: used when there’s a history of TB infection or old inactive disease that doesn’t require immediate treatment but needs to be noted for U.S. public health tracking.
- Class A TB: reserved for active, untreated TB disease. This blocks admissibility until treatment is completed and documented.
USCIS updated its validity guidance for Form I-693 in 2023: forms signed on or after November 1, 2023 no longer expire and retain their evidentiary value indefinitely, while forms signed before that date generally retain value for two years from the signature date. That distinction matters here because a referral to the health department can push your signing date back. If a health department evaluation takes six weeks, your civil surgeon simply can’t sign until it’s resolved, which pushes your I-693 completion date later than you may have planned around your filing deadline.
If USCIS issues a Request for Evidence tied to TB findings, it’s almost always because the submitted I-693 shows an incomplete referral note or missing treatment documentation. The fix is the same as avoiding the RFE in the first place: complete records, submitted at the exam, not after.
Common Mistakes That Delay I-693 for Applicants With Prior TB
The mistakes here are predictable, and almost all of them are avoidable with a little advance planning.
- Relying on memory instead of paperwork. Telling the civil surgeon “I was treated for TB a few years back” without a single signed document behind it forces the clinic to treat you as if you have no history at all, meaning fresh testing and imaging from scratch.
- Assuming a BCG vaccine scar exempts you from TB screening. It doesn’t. BCG can affect how a TST is interpreted, but it has no bearing on IGRA results and doesn’t exempt anyone from the initial screening requirement.
- Showing up with incomplete treatment records. A pharmacy printout showing three months of a six-month regimen raises more questions than it answers.
- Not requesting prior chest x-ray images, only the written report. A civil surgeon comparing old and new films side by side can often confirm stable scarring in minutes; working from a report alone sometimes isn’t enough to rule out referral.
Pro Tip: Request your records the same week you schedule your civil surgeon appointment, not the week before. Health departments and hospital records offices routinely take longer than clinics, and the records request is almost always the longest step in this entire process, not the exam itself.
Clinics that focus exclusively on immigration exams tend to catch these gaps before they become referrals, because reviewing TB history is something staff handle daily rather than occasionally. Schedule your civil surgeon visit only after you’ve gathered records, or at minimum requested them, so your exam date isn’t wasted on a visit that ends in “come back once you have X.”
If You Have No Prior TB Records at All
Sometimes the records genuinely don’t exist, or the provider who treated you has closed, moved, or can’t locate the file. This isn’t rare, and civil surgeons see it regularly enough to have a standard approach.
Without documentation, the civil surgeon follows CDC Technical Instructions as if you have no known history: an IGRA for anyone 2 or older, and a chest x-ray if that test comes back positive or your history suggests prior TB. There’s no penalty for not having records; the process simply defaults to full screening rather than accepting a shortcut.
A few practical paths forward:
- Contact the original treating clinic, hospital, or health department directly and request a full records release; most turn these around in 5 to 15 business days, though public health departments can run slower.
- If original records are truly unobtainable, pharmacy dispensing histories and discharge summaries can serve as secondary evidence of past treatment, though the civil surgeon will typically still run current testing regardless.
- Ask your pharmacy for a printed medication history going back as far as their system allows; many retain records for several years and can produce this same day.
- Consider scheduling your civil surgeon appointment at a clinic that offers on-site IGRA testing and coordinates radiology directly, since that alone removes one full round trip from a process that already has enough moving parts.
There’s no time limit on how old your prior treatment can be for it to count, but the absence of documentation means the civil surgeon has to rebuild your TB status from current evidence rather than accepting your history at face value.
Our Take on Prior TB History and I-693 Delays
The pattern we see most often isn’t dishonesty. It’s applicants who genuinely believe a verbal history or a half-remembered treatment course will be good enough, and it simply never is. USCIS built the I-693 process around documentation, not applicant testimony, and that’s not going to change.
We’ve specialized exclusively in immigration medical exams since 2007, which means TB history questions come up in nearly every week’s appointments. What consistently works is treating the records-gathering phase as part of the exam itself, not a footnote before it. Our standard processing runs about 3 days, with a 2-day expedited option when a filing deadline is close, but neither timeline means much if a referral is sitting in the middle of it.
Most prior-TB cases resolve without complication once complete records are on the table at the first visit. The rare cases that spiral into RFEs or long delays are almost always missing one of the three items we mentioned at the outset: signed test results, prior imaging, or treatment completion proof.

FAQ
Are TB tests required for the I-693 form?
Yes. Every applicant age 2 and older must undergo an initial TB screening using IGRA or TST as part of the I-693 medical examination. A prior positive test with proper documentation may change what happens next, but it doesn’t remove the screening requirement entirely.
What are the most common I-693 errors related to TB history?
The most frequent mistakes are relying on verbal history instead of signed lab reports, bringing incomplete treatment records, and assuming a BCG vaccine scar exempts an applicant from screening. Each of these typically forces a civil surgeon to restart testing from scratch or, in the case of an abnormal chest x-ray, trigger a health department referral that delays the exam.
Can you get a green card if you have had TB?
Yes, a prior TB diagnosis doesn’t block a green card on its own. Applicants with documented completed treatment, a normal current chest x-ray, no symptoms, and no known HIV infection are typically classified “No Class A or Class B TB” and proceed with no further TB-related requirement.
How do I prove my TB status for the immigration exam?
Bring signed laboratory reports for any prior IGRA or TST, your original chest x-ray images or radiology reports, and documentation showing you completed treatment, including drug names and start and end dates. If original records aren’t available, pharmacy dispensing histories or discharge summaries can sometimes serve as secondary evidence, though the civil surgeon will likely still run a current test.
How much does an I-693 exam with prior TB history cost?
Pricing depends on which tests and services your specific case requires, since prior TB history sometimes means additional imaging or record review. Current pricing and package details are available on the Immigrationmedicalexams pricing page.
