Foreign nationals applying for US visas may face new challenges as the Trump administration has issued guidance that could deny entry based on chronic health conditions. This directive, sent to US embassies and consulates, expands the criteria for determining who may be considered a potential "public charge."

The new rules specifically mention conditions such as diabetes, heart disease, obesity, and various other chronic illnesses. Visa officers are instructed to assess whether these health issues could lead to significant medical expenses, potentially costing "hundreds of thousands of dollars' worth of care." The guidance highlights that conditions like cardiovascular diseases, respiratory diseases, cancers, and mental health issues should be closely evaluated.

Obesity is also a key focus, as it can lead to complications such as asthma and high blood pressure. The directive emphasizes that applicants must demonstrate they have sufficient financial resources to cover their medical care throughout their expected lifespan without relying on public assistance.

While health screenings have always been part of the visa application process, traditionally focusing on communicable diseases, this new approach broadens the scope significantly. Immigration advocates express concern that this policy could lead to subjective judgments by visa officers, who may not have medical expertise.

The guidance applies to nearly all visa applicants but is expected to be primarily enforced for those seeking permanent residency in the US. Current tourist and student visa applicants must still show they can financially support themselves during their stay and will not become a public charge.

This policy shift is part of a broader immigration strategy by the Trump administration, which has also recently increased fees for H-1B visas and launched investigations into potential abuses of the visa program. Experts warn that these changes may disproportionately affect older applicants and those with common chronic conditions, ultimately favouring wealthier and healthier individuals seeking to immigrate to the United States.
