What Are Medical Grounds of Inadmissibility?

Under INA § 212(a)(1), the following medical conditions are grounds of inadmissibility that can result in a green card denial:

• Communicable diseases of public health significance (such as active tuberculosis, syphilis, gonorrhea, or Hansen's disease)
• Failure to present documentation of required vaccinations
• Physical or mental disorders with associated harmful behavior
• Substance use disorders (drug or alcohol abuse or addiction)

Option 1: Medical Waiver (Form I-601)

For most medical grounds of inadmissibility, a medical waiver under INA § 212(g) is available. The waiver is filed on Form I-601, Application for Waiver of Grounds of Inadmissibility.

Waivers are available for: (1) communicable disease inadmissibility — when the applicant has received or is receiving treatment and is not a danger to public health; (2) vaccination inadmissibility — when the vaccine is medically contraindicated or contrary to religious or moral beliefs; and (3) mental disorder or substance use disorder — when the disorder is in remission or under control.

Waivers are discretionary — USCIS weighs the positive and negative factors in your case. A well-documented waiver record significantly improves the chances of approval.

Option 2: Treatment and Re-Examination

For some conditions — particularly communicable diseases — treatment may resolve the inadmissibility. For example, active tuberculosis that is successfully treated is no longer a communicable disease of public health significance. After completing treatment, you can return to the civil surgeon for a new examination, which may result in a different finding.

Similarly, a substance use disorder that is in sustained remission may no longer meet the criteria for a Class A finding at a subsequent examination.

Option 3: Appeal or Motion to Reopen

If your Form I-485 was denied, you may be able to file a motion to reopen or reconsider with USCIS, or appeal to the Board of Immigration Appeals (BIA). The grounds for appeal depend on the specific basis for the denial.

An immigration attorney can evaluate whether an appeal or motion is appropriate in your case and help you build the strongest possible record.

Working With an Immigration Attorney

Medical inadmissibility cases are complex. The interaction between the clinical diagnosis, the legal standard for inadmissibility, and the waiver requirements requires careful analysis. An immigration attorney with experience in medical inadmissibility cases is essential for navigating this process successfully.
