Does a Thyroid Condition Affect My Immigration Medical Exam?

Quick Answer

Thyroid conditions — including hypothyroidism, hyperthyroidism, Hashimoto's thyroiditis, Graves' disease, and thyroid nodules — are not grounds of inadmissibility under U.S. immigration law. Your thyroid condition will not prevent you from obtaining a green card. Bring documentation of your current thyroid medications.

Thyroid Conditions Are Not Grounds of Inadmissibility

Thyroid conditions — including hypothyroidism (underactive thyroid), hyperthyroidism (overactive thyroid), Hashimoto's thyroiditis, Graves' disease, thyroid nodules, and thyroid cancer history — are not grounds of inadmissibility under U.S. immigration law. The medical grounds of inadmissibility are limited to communicable diseases of public health significance, failure to have required vaccinations, physical or mental disorders with associated harmful behavior, and drug abuse or addiction.

Medication Documentation

If you take thyroid medications — such as levothyroxine (Synthroid) for hypothyroidism, or methimazole or propylthiouracil for hyperthyroidism — bring a list of your current medications to your appointment. This helps the civil surgeon accurately document your medical history on Form I-693. There are no special restrictions or additional requirements for applicants with thyroid conditions.

No Special Restrictions

Applicants with thyroid conditions complete the same standard immigration medical examination as all other applicants. There are no additional tests, special documentation requirements, or extra steps required because of a thyroid diagnosis. Bring your vaccination records, a government-issued photo ID, and your medication list.

Disclosing Your Condition Honestly

You should answer the civil surgeon's medical history questions honestly. If you have a thyroid condition, disclose it when asked about your medical history. This information is handled confidentially and will not negatively affect your immigration application.
