Via Syracuse University's TRAC Immigration:

The latest available data from the Justice Department show that during February 2017 the government reported 4198 new immigration convictions. According to the case-by-case information analyzed by the Transactional Records Access Clearinghouse (TRAC), this number is down 16.7 percent over the previous month.

The comparisons of the number of defendants convicted for immigration-related offenses are based on case-by-case information obtained by TRAC under the Freedom of Information Act from the Executive Office for United States Attorneys (see Table 1).

When monthly 2017 convictions of this type are compared with those of the same period in the previous year, the number of convictions was down (-16.3%). Convictions over the past year are still much lower than they were five years ago. Overall, the data show that convictions of this type are down 27.4 percent from levels reported in 2012.
