Qualification Depends on the Type of Finding

There is no single qualification standard for medical waivers — the requirements differ depending on which ground of inadmissibility triggered the Class A finding. INA § 212(g) provides three separate waiver grounds, each with its own eligibility requirements.

Before evaluating whether you qualify, you need to know which type of Class A finding is on your Form I-693. Ask the civil surgeon to explain the finding, or request a copy of the form before it is sealed.

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

To qualify for a waiver of communicable disease inadmissibility (such as active TB), you must demonstrate that: (1) you have received or are receiving treatment for the condition, (2) the condition is under control or in remission, and (3) you are not a danger to public health.

USCIS also considers: family ties in the United States, the potential public health impact, and your overall immigration history. A qualifying relative (U.S. citizen or LPR spouse or parent) is not required for this waiver, but family ties are a positive factor.

Vaccination Waiver (§ 212(g)(2))

To qualify for a waiver of vaccination inadmissibility, you must show either: (1) a medical contraindication — the required vaccine is medically contraindicated for you, documented by the civil surgeon — or (2) a religious or moral objection — the required vaccine is contrary to your religious beliefs or moral convictions, supported by a detailed personal statement and evidence of sincerity.

The medical contraindication waiver has a high approval rate when properly documented. The religious/moral objection waiver requires a more detailed showing and is evaluated more carefully by USCIS.

Mental Disorder / Substance Use Disorder Waiver (§ 212(g)(3))

To qualify for a waiver of inadmissibility based on a mental disorder or substance use disorder with associated harmful behavior, you must demonstrate that: (1) you have received or are receiving treatment for the condition, (2) the condition is in remission or under control, and (3) you are not likely to engage in harmful behavior in the future.

For this waiver, USCIS also evaluates: the nature and severity of the harmful behavior, the applicant's treatment history and compliance, the prognosis from the treating clinician, and the hardship to qualifying relatives if the waiver is denied.

The Hardship Requirement

For most medical waivers, demonstrating extreme hardship to a qualifying relative (U.S. citizen or LPR spouse or parent) strengthens the waiver record significantly. While hardship is not always a formal requirement for medical waivers (unlike some other waiver types), it is a positive discretionary factor that USCIS weighs.

Hardship evidence should be specific and documented — medical conditions of the qualifying relative, financial dependence, minor children who would be affected, and evidence that the qualifying relative cannot relocate.

Discretionary Factors

Even if you meet the technical eligibility requirements, USCIS has discretion to deny the waiver based on negative factors. Negative factors include: a history of non-compliance with treatment, criminal history related to the condition, multiple prior treatment failures, and a poor prognosis. Positive factors include: strong family ties, employment history, community ties, and a compelling hardship showing.
