The six-factor test many courts use to decide whether an agency's delay has crossed the line into unreasonable.

When a court evaluates whether an immigration delay is legally "unreasonable," many judges turn to a six-factor framework first articulated in Telecommunications Research & Action Center v. FCC, commonly called the TRAC factors.

The six factors, summarized

Courts generally consider: (1) the time agencies take to act should be governed by a rule of reason; (2) where Congress has provided a timetable, that timetable may supply content for the rule of reason; (3) delays reasonable in the sphere of economic regulation are less tolerable when human health and welfare are at stake; (4) the court should consider the effect of expediting delayed action on agency activities of a higher or competing priority; (5) the court should consider the nature and extent of the interests prejudiced by the delay; and (6) the court need not find bad faith to hold agency action unreasonably delayed.

How the factors interact

No single factor is automatically decisive. Courts weigh them together, often placing significant weight on the length of delay relative to published processing benchmarks, and on the seriousness of the harm the delay is causing the petitioner.

Special weight for human welfare cases

Because many immigration matters affect an individual's ability to work, travel, reunite with family, or maintain lawful status, courts applying the TRAC factors frequently treat immigration delays as falling within the "human health and welfare" category that receives heightened scrutiny compared to purely economic regulatory delays.

The "competing priorities" factor as the government's strongest argument

Agencies frequently argue that ordering expedited action on one case simply moves another equally deserving applicant further back in line — the "zero-sum" argument. Courts have responded to this argument inconsistently, and it remains one of the most contested issues in TRAC-factor litigation.

Practical takeaway for petitioners

A strong TRAC-factor petition documents the specific length of delay compared to official processing time data, and explains concretely — not abstractly — how the delay is harming the individual petitioner.
