A coalition of 24 states and the District of Columbia filed a lawsuit in federal court Tuesday challenging a Trump administration rule that limits access to federal student loans for borrowers earning a graduate degree in several popular, healthcare-related fields.

"Higher education is expensive, and our health care system is already under immense strain," New York Attorney General Letitia James said in a statement. "This rule will shut talented people out of critical professions and leave communities with fewer health care providers they desperately need."

At issue is a pair of complex changes that, taken together, drew the ire of the American Nurses Association and triggered Tuesday's lawsuit.

First, Republicans passed new limits on graduate student loans as part of last year's One Big Beautiful Bill Act. The law does not change limits for undergraduate borrowers, including those attending undergraduate nursing programs, but it dramatically scales back how much graduate students can borrow. Previously, grad students could borrow up to the cost of their program, but the new limits cap annual borrowing for most at $20,500 with a total limit of $100,000.

Arizona, California, North Carolina, Kentucky and Nevada are among the states that joined the lawsuit, which focuses on a rule that essentially outlines an exemption to the limits.

In implementing the changes in the One Big Beautiful Bill Act, the Trump administration has scaled back the types of graduate degrees that qualify as "professional" and for which students can borrow up to $50,000 a year and $200,000 overall. It is limiting those exempted programs to 11 categories: chiropractic, clinical psychology, dentistry, law, medicine, optometry, osteopathic medicine, pharmacy, podiatry, theology and veterinary medicine. Nursing, physical therapy and nurse anesthesia are some of the many healthcare-related programs excluded from that short list of professional degrees.

A press release announcing the lawsuit argues that the Trump administration "issued a final rule unlawfully narrowing" the pre-existing federal definition of a professional degree. It says, "The rule imposes new restrictions not enacted by Congress, leaving many health care and other professional degree programs unable to qualify for the higher loan limits."

What's more, in the lawsuit itself, the plaintiffs point out that the department's list of professional degree examples "was taken from a regulation that had not been changed since the 1950s, a time when graduate programs in nursing and other healthcare professions barely existed."

Late last year, in a fact-sheet titled "Myth vs. Fact," the Education Department noted that these new loan caps "are limited to graduate programs and have no impact on undergraduate nursing programs, including four-year bachelor's of science in nursing degrees and two-year associate's degrees in nursing. 80% of the nursing workforce does not have a graduate degree."

Still, last month, when the Trump administration finalized its rule, the American Nurses Association said it was "profoundly dismayed."
