On August 18, 2026, a coalition of university groups and labor unions filed suit in the U.S. District Court for the District of Massachusetts to block the rule ending duration of status that I wrote about last month. They filed a motion for a preliminary injunction along with the complaint.
The lawsuit claims that DHS failed to adequately assess the rule’s costs and benefits, didn’t meaningfully respond to public comments, didn’t consider less burdensome alternatives, and gave the public an inadequate comment period.
Here’s what actually matters for you right now
The rule is still scheduled to take effect September 15, 2026. Filing a complaint and a motion for a preliminary injunction doesn’t pause anything by itself. A judge has to grant the injunction, and that takes a hearing, briefing, and time, none of which the plaintiffs have much of. Four weeks is not a lot of runway to get a federal judge to block a DHS rule and therefore clients should prepare for September 15 for the rule to take effect.
I’d give you the same advice I gave in my last article, and this lawsuit doesn’t change it. If you’re on Day 1 CPT, or any F-1 status that will need a USCIS extension after September 15, figure out your fixed admission end date now and start building the documentation file you’ll need for that extension. Don’t wait to see how the injunction motion comes out. If the court grants it, you’ve lost nothing by being ready early. If the court denies it, or simply hasn’t ruled by September 15, you’re not scrambling.
Litigation like this can also drag on for months, sometimes years regardless of the initial ruling on the injunction, so even a loss at the preliminary injunction stage doesn’t mean the underlying challenge is dead. I’ll follow this case and update you as it moves, but the planning advice for anyone currently in F or J status doesn’t change: assume the rule takes effect on schedule, and treat any relief from this lawsuit as a bonus, not a plan.
