A massive conservative group is taking President Donald Trump to court over a "cost-prohibitive" move for businesses.

The U.S. Chamber of Commerce, the world's largest business federation, announced Thursday that it filed a legal challenge to the Trump administration’s $100,000 fee on H-1B visa petitions, Bloomberg reports.

"The Chamber’s litigation argues that the new fee is unlawful because it overrides provisions of the Immigration and Nationality Act that govern the H-1B program, including the requirement that fees be based on the costs incurred by the government in processing visas," the organization announced in a statement.

“The new $100,000 visa fee will make it cost-prohibitive for U.S. employers, especially start-ups and small and midsize businesses, to utilize the H-1B program, which was created by Congress expressly to ensure that American businesses of all sizes can access the global talent they need to grow their operations here in the U.S.," Neil Bradley, executive vice president and chief policy officer at the organization, said in a statement.

Bradley praised Trump's aggressive immigration policies, arguing "the president deserves credit for securing our nation’s border" and says he wants Congress and the administration to work "together on common-sense reforms to improve the visa process for skilled workers."

“President Trump has embarked on an ambitious agenda of securing permanent pro-growth tax reforms, unleashing American energy, and unraveling the overregulation that has stifled growth. The Chamber and our members have actively backed these proposals to attract more investment in America. To support this growth, our economy will require more workers, not fewer," Bradley
