So You Need to Fill Out the I-693
The Form I-693 is the Report of Medical Examination and Vaccination Evaluation. It's the paperwork that proves you've been screened for communicable diseases and don't have any of the grounds of inadmissibility that USCIS looks for during green card applications. Most people get handed this form by their immigration attorney or find it as a link in an email from someone who processed their case before. The form itself is blank. It stays blank until a licensed civil surgeon fills it out and signs it.Here's how the actual process works in practice. You find a civil surgeon in your area. Not every doctor who does physicals can complete this form. You have to call around and ask if they perform USCIS medical exams. The ones that do usually run between $200 and $400 depending on the state. You schedule an appointment, show up, and they do a tuberculosis test, blood work for syphilis and other treatable conditions, a physical exam, and a vaccination review. If you're missing vaccines, they can administer them at the appointment. If you have a reactive TB test, that triggers additional follow-up. Most people get cleared in under an hour. I've had more people come to me with problems after the fact than people who get it right the first time. The most common failure point is the vaccination section. Civil surgeons aren't required to verify vaccine records through a titers database or state immunization registry. They usually just ask if you know whether you got the vaccines, and if you shrug, they check the box saying you received them. That sounds fine until USCIS flags it six months later and requests additional evidence. I had a client whose civil surgeon marked Hepatitis B as administered when he clearly hadn't received it. We ended up having to get actual lab titers done through a separate lab, print the results, and submit them as a supplemental document. That cost another $120 and took three weeks. The workaround is simple: bring your actual vaccination records to the appointment. Print them out, highlight the dates, and hand them directly to the surgeon. It takes twenty seconds on their end and saves you from a Request for Evidence down the line. The filing window for the form is another thing people mess up. The I-693 is valid for two years from the date the civil surgeon signs it. But here's the counter-intuitive part that nobody tells you: if you file your adjustment of status application without the I-693 and request a deferral, the two-year clock starts ticking the moment the surgeon completes the exam, not the moment you file. So if there's a three-month gap between your exam and when you actually submit your I-693 to USCIS along with your I-485, you're losing three months of validity for no reason. File the form as close to the exam date as possible. If you're doing a consular processing route instead, you have more flexibility because the form goes to the National Visa Center and the expiry is tracked differently.
There are also situations where the medical exam itself creates a problem that could be avoided entirely. Prior to 2021, certain drug-related offenses made you permanently inadmissible regardless of what the civil surgeon found on the exam. The rules shifted, but the TB screening section still catches people off guard. A reactive PPD skin test doesn't automatically mean you have active tuberculosis. It means you need a chest X-ray and possibly a sputum culture. The civil surgeon handles the initial screening. If you test positive, they send you for the follow-up testing. That additional work is not included in the standard exam fee. Expect to pay extra, usually between $150 and $350 depending on what diagnostics are needed. Some surgeons build a buffer into their pricing. Most don't. Ask upfront whether the quoted price includes TB follow-up or if that's billed separately. Another practical detail: civil surgeons can fill out the I-693 digitally through the USCIS online system now. The old paper forms are still accepted, but digital submission has a 30-day lockout period. Once the surgeon submits the form electronically, they cannot make changes to it. If there's a mistake on the form, you have to go back to the surgeon and ask them to void the submission and resubmit a corrected version. I watched one person waste eight days waiting for a surgeon to process a correction after they realized the vaccine dates were wrong. Surgeons are busy and often slow to respond to these requests because it's unpaid work for them. Double-check everything on the form before the surgeon finalizes it. Look at every page. Make sure the name, date of birth, and A-number match exactly what's on your immigration documents. A mismatch on the A-number between the I-693 and your I-485 is a classic cause of delays. The form also requires you to list all prior immigration history including previous visa denials, prior adjustment applications, and any previous medical examinations submitted to USCIS. This is where people get confused. You don't need to re-submit I-693 forms from past applications. The current form has a section asking about prior exams just for transparency. Mark it accurately. If USCIS already has your previous medical on file from an earlier filing, flag that clearly so the officer doesn't waste time looking for it. I've seen cases where incomplete answers to that section triggered secondary review and added two weeks to processing.
For people with chronic conditions like HIV, hepatitis, or a history of substance abuse, the civil surgeon still marks the form as admissible in most cases because these aren't grounds of inadmissibility unless they're untreated and pose a public health risk. But if you're on medication for a condition, bring a current letter from your treating physician describing the treatment and confirming compliance. The civil surgeon may ask for it. Having it ready prevents unnecessary delays at the appointment. Without it, they might defer the exam and ask you to return with additional documentation, which means paying for a second visit. One edge case worth noting: if you're applying from outside the United States through consular processing, the medical exam is done at an authorized panel physician, not a civil surgeon. The exam is fundamentally the same, but the panel physician is located in your home country and the results go directly to the embassy or consulate. The two-year validity still applies. If your medical expires before your visa interview, you need to retake the exam. Factor that timeline in. If your priority date has been current for a long time and your case is nearing interview, schedule the medical closer to the interview date rather than months ahead. The downside to everything I've described is that there's no quality control over the exam process. Different civil surgeons have different standards. One might carefully verify every vaccine record. Another might rubber-stamp everything and move to the next patient. There's no audit that catches these discrepancies before USCIS sees them. The best approach is to treat the appointment like a formal evaluation, not a routine checkup. Come prepared. Ask questions. Verify that everything on the form is correct before it's submitted. The exam itself is straightforward. The paperwork surrounding it is where the real problems live.

If you need the form, it's available on the USCIS website as PDF. Download the current version before your appointment. Older versions get rejected and you'll have to redo the exam. The form is updated periodically with new sections or revised questions. Using a superseded version adds days or weeks to your case. Check the revision date at the bottom of the form. If it's older than two years, you probably need the latest one.
