Navigating the Medical Exam for Green Card Applicants
A Clear, Step-by-Step Guide to the I-693 Process
Applying for a green card in the United States involves several important steps—and one of the most commonly misunderstood is the medical exam requirement.
If you’re searching for answers about the immigration medical exam, you’re not alone. Many applicants feel overwhelmed by:
- What the exam includes
- Which tests are required
- How to prepare
- Where delays typically happen
At Lab On Demand, we’ve streamlined the process for patients across Indiana—including Indianapolis, Carmel, Fishers, Zionsville, and Westfield—by offering a lab-integrated approach that reduces delays and confusion.
This guide will walk you through everything you need to know.
What Is the Green Card Medical Exam?
The green card medical exam—officially documented on Form I-693—is required by U.S. immigration authorities to ensure applicants do not have:
- Communicable diseases of public health significance
- Missing required vaccinations
- Medical conditions that may impact admissibility
The exam must be completed by a USCIS-designated civil surgeon.
Why This Exam Matters
The I-693 form is not just paperwork—it is a critical component of your application.
Errors, delays, or missing lab work can:
- Delay your green card approval
- Trigger Requests for Evidence (RFEs)
- Require repeat visits

Step-by-Step: The Green Card Medical Exam Process
Understanding the sequence helps reduce stress and avoid delays.
Step 1: Schedule Your Appointment
You must visit a USCIS-approved civil surgeon.
At Lab On Demand, we coordinate lab work and medical exam requirements to create a more efficient process.
Step 2: Complete Required Lab Testing
Most applicants will need:
- Tuberculosis (TB) screening
- Syphilis blood test
- Gonorrhea screening
Why Lab Integration Matters
One of the biggest causes of delay is:
- Sending patients to separate lab facilities
- Waiting days for results
Our integrated model helps:
- Reduce turnaround time
- Improve accuracy
- Minimize repeat visits
Step 3: Vaccination Review
You will need to show proof of required vaccinations, which may include:
- MMR (measles, mumps, rubella)
- Varicella (chickenpox)
- Tdap
- Influenza (seasonal)
- COVID-19 (depending on current requirements)
What If You’re Missing Vaccines?
You can:
- Receive them during the process
- Provide documented immunity
Step 4: Physical Examination
The civil surgeon will evaluate:
- General health
- Medical history
- Signs of communicable disease
This is typically straightforward and non-invasive.
Step 5: Form I-693 Completion
Once everything is complete:
- The doctor fills out Form I-693
- The form is sealed in an envelope
🚫 Do NOT open this envelope—it must be submitted as-is.
Common Delays (And How to Avoid Them)
Many applicants experience unnecessary delays.
1. Missing Lab Results
- Results not completed before appointment
- Incorrect or incomplete testing
2. Incomplete Vaccination Records
- No documentation
- Uncertainty about prior vaccines
3. Fragmented Care
- Lab in one location
- Doctor in another
- Lack of coordination
How Lab On Demand Solves This
We streamline:
- Lab testing
- Documentation
- Communication
This reduces:
- Wait times
- Errors
- Stress
Understanding the Science Behind Required Tests
The I-693 exam is grounded in public health protocols.
Tuberculosis (TB) Testing
Typically done via:
- Blood test (IGRA)
Why it matters:
- TB is a communicable disease
- Screening ensures early detection
Syphilis Testing
Blood test required for:
- Applicants aged 18–44
Gonorrhea Screening
Performed using:
- Urine testing or swab
These tests are designed to:
- Protect public health
- Ensure early treatment if needed
How Long Does the Process Take?
With efficient coordination:
- Lab results: 1–3 days
- Exam completion: Same or next visit
- Final form: Typically within a few days
Without coordination, this can extend significantly.
Choosing the Right Provider
Many applicants search for:
- “immigration medical exam near me”
- “I-693 doctor near me”
But the better question is:
