Immigration Medical Exam (I-693) Complete Guide
The Immigration Medical Exam (I-693) is a critical step in many immigration applications, especially for those applying for adjustment of status. This exam ensures applicants meet U.S. health standards and do not pose public health risks. Understanding how the process works, what documents are required, and how to avoid delays can significantly improve your chances of approval.
For applicants in the Houston area, including Harris County, navigating the I-693 process can feel overwhelming due to physician availability and documentation requirements. Many individuals searching for immigration help in Houston or immigration paperwork assistance in Harris County benefit from working with experienced professionals who understand how to properly organize and submit sealed medical exam forms without errors.

What Is Form I-693 and Why It Matters
Purpose of the Immigration Medical Exam
Form I-693, officially titled Report of Immigration Medical Examination and Vaccination Record, is required by U.S. Citizenship and Immigration Services (USCIS) to verify that applicants are admissible on health-related grounds. The exam is conducted by a USCIS-designated civil surgeon.
Who Needs to Complete Form I-693
Most applicants applying for a green card from within the United States must complete Form I-693. This includes family-based applicants filing through Adjustment of Status services and those following the process outlined in the Adjustment of Status checkllist.
What Happens During the Medical Exam
Required Health Screening
The immigration medical exam typically includes a physical examination, tuberculosis screening, vaccination review, and testing for communicable diseases. The civil surgeon will also review your medical history.
Vaccination Requirements
Applicants must show proof of required vaccinations. Missing vaccinations may be administered during the appointment. Proper documentation is essential to avoid delays.
Sealed Envelope Requirement
Once completed, the doctor provides a sealed Form I-693. Do not open it. USCIS will reject the form if the seal is broken.
Common Mistakes That Delay I-693 Processing
Submitting an Expired Form
Form I-693 has a validity period. Submitting an outdated medical exam can lead to Requests for Evidence (RFEs). Learn how to respond effectively in the RFE Response Guide.
Incomplete Vaccination Records
Missing documentation or incomplete immunization history is one of the most common issues applicants face.
Improper Submission Timing
Applicants can submit Form I-693 with their application or bring it later to an interview. Strategic timing can help avoid expiration issues.
