USCIS-authorized physicians in Houston (Civil Surgeon)

What a civil surgeon is, why only they can sign your I-693, how to check a doctor is USCIS-designated and what to ask before your visit in Houston.

Searching for "immigration exam doctor in Houston" returns plenty of results, but not all of them can help. For the I-693 exam you need a specific kind of doctor: a civil surgeon. Here is what that means, how to check it and what to ask before you pay.

What is a civil surgeon?

A licensed physician officially designated by USCIS to perform immigration medical exams inside the United States. The designation comes from USCIS, not from the state or a medical board, and it can be revoked. A doctor without it can treat you for anything else, but their signature on Form I-693 is not valid.

What do they do, and what don't they do?

They do:

  • Review your medical history and vaccination records.
  • Perform the physical exam and order the tests the CDC requires, such as tuberculosis and, depending on age, syphilis and gonorrhea.
  • Give or refer you for any missing vaccines.
  • Complete, sign and hand you Form I-693 in a sealed envelope.

They don't:

  • Decide whether your green card is approved; USCIS does.
  • Give legal advice or prepare your I-485. That is your attorney's or accredited representative's job.
  • "Fix" results or skip required tests.

How can I check that a doctor is designated?

USCIS has an official civil surgeon locator. Open the USCIS Find a Doctor tool, enter your ZIP code (for example, 77092) and check that the doctor's name appears. If a clinic says it has a civil surgeon, ask for the doctor's name and look it up there.

What should I ask before booking?

  1. What is the total cost? USCIS does not set the price. Ask what is included and what is extra (tests, vaccines, X-ray).
  2. Do you give vaccines at the clinic? That saves you a trip elsewhere.
  3. How many days do results take? Some tests take a few days, so the form is usually not ready the same day.
  4. Can I be seen in Spanish? Understanding every history question avoids mistakes.
  5. Do you use the current edition of the form? Since July 2025 USCIS only accepts the 01/20/25 edition.

Red flags

  • They offer the form without an exam or without tests.
  • They cannot tell you the name of the doctor who signs.
  • They guarantee your case will be approved.

When is the best time for the exam?

Since December 2024, Form I-693 must be filed together with Form I-485. The best time is when your package is almost complete, so you do not have to repeat steps.
