When Is a Medical Waiver Required?

A medical waiver under INA § 212(g) is required when an applicant receives a Class A inadmissibility finding on Form I-693. Class A findings can result from: (1) a communicable disease of public health significance (§ 212(g)(1)), (2) failure to present documentation of required vaccinations (§ 212(g)(2)), or (3) a physical or mental disorder with associated harmful behavior (§ 212(g)(3)).

Each ground has different waiver requirements and standards. Attorneys must identify the specific ground of inadmissibility before building the waiver record.

Waiver for Communicable Disease (§ 212(g)(1))

A waiver for communicable disease inadmissibility (including active TB) requires a showing that: (1) the applicant has received or is receiving treatment for the condition, (2) the condition is under control or in remission, and (3) the applicant is not a danger to public health.

The waiver is discretionary. USCIS weighs the applicant's medical status, treatment compliance, family ties in the United States, and the potential public health impact. A strong waiver record includes current medical documentation from the treating physician, evidence of treatment compliance, and a public health assessment.

Waiver for Vaccination Requirement (§ 212(g)(2))

A waiver for failure to present vaccination documentation is available on two grounds: (1) the required vaccine is medically contraindicated for the applicant, or (2) the required vaccine is contrary to the applicant's religious beliefs or moral convictions.

The medical contraindication waiver requires documentation from a physician (typically the civil surgeon) certifying that the vaccine is contraindicated. The religious/moral objection waiver requires a detailed personal statement explaining the basis for the objection and evidence that the objection is sincere and longstanding.

Waiver for Mental Disorder With Harmful Behavior (§ 212(g)(3))

A waiver for inadmissibility based on a physical or mental disorder with associated harmful behavior requires a showing that: (1) the applicant has received or is receiving treatment for the condition, (2) the condition is in remission or under control, and (3) the applicant is not likely to engage in harmful behavior in the future.

This waiver is the most complex of the three medical waivers. The record must include current psychiatric or psychological evaluation, evidence of treatment compliance, documentation of any prior harmful behavior and its resolution, and a prognosis from the treating clinician.

Building the Medical Documentation Record

The foundation of any medical waiver is the medical documentation record. This should include: (1) a current evaluation from the treating physician or specialist, (2) a summary of the diagnosis and treatment history, (3) current treatment plan and medications, (4) prognosis and assessment of future risk, and (5) documentation of treatment compliance.

Attorneys should work with the civil surgeon and the client's treating physicians to obtain comprehensive documentation. A letter from the treating physician that directly addresses the waiver standard — not just a general medical summary — is far more persuasive than generic medical records.

Hardship Evidence for Qualifying Relatives

For most medical waivers, the applicant must demonstrate that denial of the waiver would result in extreme hardship to a qualifying relative (U.S. citizen or lawful permanent resident spouse or parent). The hardship showing is often the most important part of the waiver record.

Hardship evidence should be specific and documented. Generic statements about emotional hardship are not sufficient. Strong hardship evidence includes: medical conditions of the qualifying relative that require the applicant's care, financial dependence, minor children who would be affected, and evidence that the qualifying relative cannot relocate to the applicant's home country.

Attorneys should interview the qualifying relative in detail and obtain supporting documentation — medical records, financial records, school records for children, and personal statements from family members.

Timing and Coordination With the Civil Surgeon

Attorneys should begin building the waiver record as soon as a Class A finding is anticipated — not after the finding is made. If the client's medical history suggests a likely Class A finding, start gathering medical documentation and hardship evidence before the exam.

After the Class A finding is made, coordinate with the civil surgeon to obtain a supporting letter for the waiver. The civil surgeon's assessment of the applicant's current medical status and prognosis is a critical component of the waiver record.

Common Waiver Record Deficiencies

The most common deficiencies in medical waiver records are: (1) medical documentation that is outdated or does not address the waiver standard, (2) hardship evidence that is generic rather than specific and documented, (3) failure to address the specific ground of inadmissibility, and (4) missing supporting letters from treating physicians. Attorneys should review the waiver record against the specific statutory standard before submission.
