For nearly half a century, an international student admitted to the United States could stay for as long as their program lasted - a policy called 'duration of status,' in place since 1979. On July 16, the Department of Homeland Security finalized a rule ending it [1]. In its place: a fixed four-year admission cap, after which students must file for a discretionary extension that US Citizenship and Immigration Services can deny, with no appeal [1].

The rule, 553 pages long and effective September 15, is expected to affect more than a million international students, along with exchange visitors and foreign journalists on J and I visas [1][2]. Four years is less time than most doctoral programs take, and often less than an average undergraduate degree once a change of major or a co-op is figured in; optional practical training, the work period after graduation, adds more [1]. Every student who runs past the cap will have to ask USCIS for more time - an agency currently sitting on a backlog of 11.65 million cases, with some extension waits already over a year [1].

DHS says the rule ends 'foreign student visa abuse.' The number it points to is small: an estimated 2,100 'forever students' who lingered on F-1 visas over an eleven-year span, from 2000 to 2010 [3]. Set that beside the more than one million students the four-year cap now applies to, and the justification names roughly two-tenths of one percent of the people the rule reaches [1][3].

DHS justifies ending ‘duration of status’ by pointing to ~2,100 ‘forever students’ from 2000-2010 - against the 1,000,000+ international students the new four-year cap applies to [1][3].

The record worth completing is that mismatch. A rule sold as closing a loophole exploited by a couple thousand people is being written onto the status of everyone - the PhD candidate in year five of a six-year program, the undergraduate who switched majors, the researcher whose grant runs long - each now dependent on a discretionary, non-appealable decision from a backlogged agency to stay in the country legally [1][3]. International-education leaders, per Inside Higher Ed, say the rule 'solves a problem that doesn't exist' [1].

What the rule does is convert a status that used to last as long as the studying did into one that expires on a clock, renewable only at USCIS's discretion [1]. The stated target is 2,100 people who overstayed a decade ago. The reach is a million students who have not [1][3].
