The Trump administration is reportedly seeking to levy steep fines on some immigrants in the country illegally in its latest move to crack down on illegal immigration.

Documents obtained by NPR show that the government is seeking to issue fines of up to $500,000 to immigrants who, for example, have not left the U.S. after being ordered to do so.

The news of the fines comes a week after the White House postponed planned Immigration and Customs Enforcement raids targeting migrants in the U.S. illegally.

Trump at the beginning of his term signed an executive order promising that the administration would begin collecting "all fines and penalties" issued by law to immigrants in the country illegally.

"It is the intention of ICE to order you to pay a fine in the amount of $497,777," reads a letter sent June 25 from ICE to a migrant named Edith Espinal Moreno, according to NPR.

The Immigration and Nationality Act outlines that immigrants in the country illegally who do not leave or take steps to leave after being ordered to do so are subject to fines of no more than $500 a day, though immigration lawyers told NPR that they had not heard of the law being used in this way previously.

ICE officials said that immigrants who do not meet the obligations of a removal order may receive a fine notice and then have 30 days to respond to the notice before a final decision is made as to whether a fine should be issued.
