Table 1. Civil Immigration Filings

The latest available data from the federal courts show that during January 2015 the government reported 131 new civil filings that were classified by nature of suit as immigration matters. According to the case-by-case information analyzed by the Transactional Records Access Clearinghouse (TRAC), this number is down 13.2 percent over the previous month when the number of civil filings of this type totaled 151.

The comparisons of the number of civil immigration filings are based on case-by-case court records which were compiled and analyzed by TRAC (see Table 1).

Various federal statutes are invoked in lawsuits concerning immigration matters. Among the most commonly cited in January 2015 were 28 USC 2241 Petition for Writ of Habeas Corpus (24.4%), 28 USC 1361 Petition for Writ of Mandamus (16.8%), 8 USC 1329 Writ of Mandamus to Adjudicate Visa Petition (14.5%) and 8 USC 1446 Petition for Naturalization Hearing (10.7%).

When monthly 2015 civil immigration filings are compared with those of the same period in the previous year, their number is only slightly down (-1.4%). Civil immigration filings for January 2015 are lower than they were for the same period five years ago. Overall, the data show that civil filings of this type are down 13.3 percent from levels reported in January 2010.
