Who is exempt from the medical examination requirement for adjustment of status?

The correct choice highlights that certain nonimmigrant spouses, fiancés, or children of U.S. citizens are exempt from the medical examination requirement for adjustment of status. This exemption is rooted in the recognition that these individuals are typically in a unique position due to their relationship with a U.S. citizen and their intent to adjust their status based on family connections rather than employment or other grounds that usually necessitate a more stringent review process.

This provision acknowledges the immediate familial ties and eligibility for lawful permanent residence that these nonimmigrants possess. It facilitates the adjustment process for those who are applying directly due to their relationship with a U.S. citizen, making it less burdensome as they may have already undergone certain screenings during their visa application process.

In contrast, nonimmigrant workers, for instance, do not qualify for this exemption because they are primarily adjusting status based on employment rather than family ties. Similarly, all immigrant applicants are generally required to undergo medical examinations to ensure they meet health-related requirements. Individuals with prior visa revocation also do not have an automatic exemption; in fact, their situation often involves more scrutiny regarding their eligibility for adjustment of status rather than a waiver of the medical examination.
