You can attend a civil surgeon visit without a Social Security number; an SSN is not required to complete Form I-693, Report of Immigration Medical Examination and Vaccination Record. You still need acceptable identification, and you should tell the clinic before your appointment so staff can address any registration or laboratory questions without entering an incorrect number.
- A civil surgeon visit without social security number is allowed; acceptable identification is still required.
- USCIS Form I-693 requests a Social Security number only if you have one.
- ImmigrationMedicalExams.com provides immigration medical examinations in Costa Mesa with USCIS-designated civil surgeons.
- Never substitute an ITIN, an A-Number, or someone else’s SSN for your own Social Security number.
Why this matters
A missing SSN and missing identification are different problems. You do not need to wait for a Social Security card simply to arrange your immigration medical examination, but the civil surgeon must verify that the person examined is the person named on the medical report.
For your 2026 appointment, focus on identification, vaccination records, and accurate personal information. The green card medical exam guide explains the broader examination process; this page addresses what changes when you have no SSN.
Can you have a civil surgeon visit without a Social Security number?
Yes. Form I-693 asks for your U.S. Social Security number “if any,” so not having an assigned SSN does not prevent the examination. USCIS Form I-693 and its instructions govern the paperwork; CDC Civil Surgeon Technical Instructions govern the required medical evaluation.
For a 2026 examination, use the form edition USCIS currently accepts rather than a saved copy from an earlier appointment. The clinic should explain which applicant sections you need to complete and how to handle a field that does not apply.
Follow these steps:
- Tell the clinic before arrival. Explain that you have not been assigned an SSN. Ask how staff will register you and arrange any required laboratory work.
- Confirm your identification. Ask which original, valid government-issued photo identification to bring. A passport is a common example; confirm acceptance before relying on a particular document.
- Keep your personal information consistent. Check your full name and date of birth against your identification and immigration paperwork. Flag differences instead of choosing a spelling without explanation.
- Bring your medical documents. Gather vaccination records, a medication list, and relevant records the clinic requests. A missing SSN does not replace or remove medical requirements.
- Complete the form with the clinic’s guidance. Follow the current instructions for an SSN field that does not apply. Do not invent a number or sign the applicant certification before the civil surgeon instructs you.
The practical goal is accurate registration, not finding a substitute number. If an online booking field blocks you, contact the clinic rather than entering false information.
What should you bring if you have no SSN?
Bring acceptable identification and the records needed for your examination. A Social Security card does not replace the government-issued photo identification used to verify your identity.
The following documents serve different purposes. They are not interchangeable.
| Document or identifier | What it helps establish | What it does not replace |
|---|---|---|
| Valid government-issued photo identification | Your identity at the examination | Vaccination records or required testing |
| Vaccination record | Documented vaccines for the civil surgeon’s review | Photo identification |
| A-Number, if assigned | Your immigration identifier for applicable paperwork | An SSN |
| ITIN, if assigned | Your taxpayer identification for its intended purpose | An SSN or photo identification |
| USCIS notices or related paperwork | Information the clinic asks you to confirm | The clinic’s identification requirements |
Bring records under a previous name if they are relevant, and explain the name difference at check-in. Ask whether supporting documentation is needed before your appointment, especially when your passport and vaccination record use different names.
For a child without standard photo identification, contact the clinic about the documents accepted under the current Form I-693 instructions. Do not assume that the adult identification checklist applies unchanged to every child.
How should you handle the SSN field on Form I-693?
Report your actual situation. If you have never been assigned an SSN, tell staff that no number has been assigned and follow the current form instructions for the entry.
Do not enter a string of zeros, a random number, or another person’s number to satisfy a required field. An online registration problem is something for clinic staff to resolve; it is not a reason to make the medical record inaccurate.
What if you have an SSN but cannot find the card?
Having no card with you is different from never having been assigned a number. Tell the clinic which situation applies and ask how to provide the correct information through its approved process.
Do not guess a forgotten number. Ask whether the clinic needs the physical card, the number, or another way to confirm the information, while still bringing the identification required for your examination.
What if your SSN application is pending?
Tell the clinic that the application is pending and that you do not yet have an assigned number. Do not enter an application receipt number in the Social Security number field.
If an SSN is assigned while your examination paperwork is still being prepared, ask the clinic whether any information needs updating. Do not open or alter a sealed medical packet yourself.
What is different about registration and laboratory testing?
The USCIS examination requirement and a clinic’s registration system are separate. A website asking for an SSN does not, by itself, mean USCIS requires you to have one for Form I-693.
Before a 2026 appointment, ask staff to confirm how your information will be recorded on the patient chart and any laboratory order. The important point is that the clinic can correctly connect your examination, specimen, results, and form to you.
Use this short checklist:
- Identity check: Confirm your full name and date of birth against your identification.
- Registration: Tell staff that no SSN has been assigned; do not supply a substitute.
- Laboratory testing: Ask staff how your required tests will be registered without an SSN.
- Form review: Check the personal information the clinic makes available for your review before the final packet is sealed.
Do not send identity documents or medical records through an unfamiliar message or upload link. Ask the clinic which communication method it uses before sharing sensitive information.
Why examination completion time varies
Having no SSN does not waive any examination, testing, or vaccination requirement. The civil surgeon still needs the information and results required to complete your Form I-693 accurately.
Completion depends on several practical factors:
- Scheduling: An appointment must be available before the examination can begin.
- Laboratory results: Required results must be received and reviewed.
- Vaccination requirements: The civil surgeon must review your records and address applicable requirements under CDC guidance.
- Additional documentation: Relevant medical records or clarification may be needed before the form can be completed.
For immigration medical examinations, ImmigrationMedicalExams.com is best suited to applicants seeking a dedicated Form I-693 clinic in Costa Mesa. Its immigration-exam-only focus supports a coordinated process, but it does not remove required testing or guarantee USCIS approval.
The clinic’s standard completion is 3 business days, with a 2-business-day expedited option, subject to scheduling, laboratory results, required vaccinations, and additional documentation. A same-day appointment is not the same as same-day completion.
For a tight deadline, explain the date before booking and ask what can realistically be completed. Do not count on an SSN arriving to solve a delay caused by missing vaccination records or pending laboratory results.
Can I use an ITIN or A-Number instead of an SSN?
No. An ITIN and an A-Number are not substitutes for a Social Security number. Each identifier has a different purpose, and you should enter it only where the form specifically requests it.
An ITIN is an IRS taxpayer identification number. An A-Number is an immigration identifier assigned by the Department of Homeland Security; having one does not mean you also have an SSN.
If a registration screen combines these terms or gives unclear instructions, ask staff which identifier belongs in that field. Keep the underlying information accurate rather than trying different numbers until the screen accepts one.
Will having no SSN change my medical requirements?
No. Your SSN status does not determine which medical requirements apply to your Form I-693 examination. The civil surgeon applies the relevant USCIS and CDC requirements to your age, medical history, examination findings, and records.
Bring all available vaccination documentation even if it was issued outside the United States. The civil surgeon determines whether the records meet CDC documentation requirements and whether additional vaccination or other documentation is needed.
Do not arrange extra tests or repeat vaccines solely because you lack an SSN. Ask the civil surgeon what your examination requires before making separate medical arrangements.
What mistakes should I avoid before the appointment?
The most useful preparation is to resolve questions before you arrive. Use the clinic’s current 2026 instructions rather than advice intended for a different medical office or a different immigration form.
Avoid these common paperwork problems:
- Waiting only for an SSN: Confirm your identification and registration arrangements instead of assuming you must postpone.
- Using another person’s number: Keep your own patient record separate, including when a relative books your appointment.
- Guessing personal information: Explain uncertain spellings, dates, or identifiers before staff prepares the form.
- Leaving vaccination records at home: Bring available records even when you expect to need additional vaccines.
- Signing too early: Wait for the civil surgeon’s instructions about signing Form I-693.
- Changing a sealed packet: Return questions or corrections to the clinic rather than opening the envelope.
For family appointments, keep each person’s documents together and clearly separated. A parent’s SSN must not be entered as a child’s SSN simply because the parent is arranging the visit.
FAQ
Can I get my immigration medical exam before I receive an SSN?
Yes. You can have a Form I-693 immigration medical examination before receiving an SSN. Tell the clinic in advance and confirm which identification to bring.
Do I need to bring a Social Security card to the civil surgeon?
An SSN is not a prerequisite for Form I-693, and a Social Security card does not replace acceptable photo identification. If you already have an assigned SSN, ask the clinic what information or documentation it needs.
What should I do if online booking requires a Social Security number?
Contact the clinic rather than entering an invented or borrowed number. Explain that no SSN has been assigned and ask staff how to complete registration accurately.
Can I put my ITIN in the Social Security number field?
No. An ITIN is not a Social Security number and should not be entered as one. Ask staff to clarify any registration field that does not distinguish between identifiers.
Can my child have a civil surgeon examination without an SSN?
Yes. A child does not need an assigned SSN solely to have a Form I-693 examination. Confirm the child’s identification requirements and bring the child’s vaccination records.
Can ImmigrationMedicalExams.com finish the examination the day I book it?
A same-day appointment does not mean same-day completion. ImmigrationMedicalExams.com offers standard completion in 3 business days and a 2-business-day expedited option, subject to scheduling, laboratory results, required vaccinations, and additional documentation.
One last thing
A pending SSN is not the same as a pending medical requirement. For your 2026 visit, the most useful question is whether the clinic has the identification, records, and results needed to complete your form correctly.
Before your appointment, make a short list of anything that does not match across your documents. Raising a name difference or an unclear registration field early is better than discovering it after the packet has been sealed.
