Oleksandr Romer, a citizen of Ukraine who is married to a United States citizen, asks that we overturn an immigration-court decision denying his motion to reopen removal proceedings as time- and number-barred, rejecting his request that the time and number limitations be tolled, ordering him removed to Ukraine, and imposing a ten-year bar on any adjustment of status because he overstayed an earlier voluntary-departure deadline. Finding that the immigration court inadequately explained its rationale for rejecting tolling and imposing the ten-year bar, we grant the petition for review, vacate the decision below, and remand.1
Romer entered the United States on a visitor’s permit in 1999. He overstayed the permit, and the government initiated removal proceedings. On November 8, 2005, an immigration judge (IJ) granted Romer voluntary departure by March 8, 2006. In an effort to remain in the country legally, Romer enlisted the services of attorney Vladislav Sirota after (he says) Sirota told him that he could successfully challenge the IJ’s decision.
Sirota’s first order of business was to file a timely motion to reopen removal proceedings — Romer’s first such motion. The IJ denied the motion on January 16, 2006, and mailed a copy to Sirota; Sirota (Romer says) never passed the message on to him. And so Romer remained in the country while his voluntary-departure deadline came and went.
Beginning in November 2005 and continuing for years, Romer and his wife (they say) called Sirota’s office once every few months to find out how the case was progressing. They say they were rarely able to speak directly with Sirota, but that they were often reassured by staff that cases like his can take time. They also say Sirota’s office advised them that Romer did not need to leave the country and could wait out his case’s resolution — even after immigration officers came to his home looking for him. In 2008, Sirota sought an additional $4,000 from Romer for another motion, claiming he had to apprise the immigration court of Romer’s wife’s change from lawful permanent resident to citizen. Romer paid the $4,000 fee in full.
On April 15, 2010, Romer was arrested, and he has remained in custody ever since. On April 25, 2010, an attorney at Sirota’s *42firm filed a motion to reopen — Romer’s second — that was nearly a carbon-copy of the first. The IJ again denied the motion, observing that Romer had already reached his limit of one motion to reopen under 8 C.F.R. § 1003.23(b).2 The IJ further determined that, because Romer had overstayed his voluntary departure period, 8 U.S.C. § 1229c(d)(l)(B)3 imposed an absolute ten-year bar on any adjustment of status.
Several days later, Romer’s wife hired attorney Gregory Romanovsky to help Romer out of his predicament. Romanovsky filed another motion to reopen — Romer’s third — this time based on Sirota’s alleged incompetence and the case Matter of Lozada, 19 I. & N. Dec. 637 (B.I.A.1988).4 Romanovsky also argued that the time5 and number limitations of § 1003.23(b) should be equitably tolled because Romer diligently pursued what he thought were legitimate means to remain in the country, and that the ten-year bar should not apply because Romer did not voluntarily overstay his term for departure but instead reasonably relied on counsel’s advice that he could remain in the United States.
For the third time, the immigration court denied Romer’s motion to reopen. The IJ brushed aside Romer’s claim that he had been misled, concluding that the new allegations were nothing more than “excuses” for disregarding the court’s then-five-year-old voluntary-departure order. The Board of Immigration Appeals (BIA) affirmed without comment, and this appeal followed. We have jurisdiction under 8 U.S.C. § 1252. See Neves v. Holder, 613 F.3d 30, 35 (1st Cir.2010); see also Kucana v. Holder, — U.S. —, 130 S.Ct. 827, 840, 175 L.Ed.2d 694 (2010).
Where the BIA affirms without issuing an opinion, we focus our review on the Id’s decision. Castillo-Diaz v. Holder, 562 F.3d 23, 26 (1st Cir.2009). We review the denial of a motion to reopen for abuse of discretion. Aponte v. Holder, 610 F.3d 1, 4 (1st Cir.2010). Abuse-of-discretion review entails significant deference to the IJ’s fact-finding and de novo review of any legal conclusions. Vaz dos Reis v. Holder, 606 F.3d 1, 3 (1st Cir.2010). The abuse-of-discretion standard also means that we review immigration courts’ explanations for at least minimal adequacy, “because ‘cursory, summary or conclusory statements ... leave us to presume nothing other than an abuse of discretion.’ ” Aponte, 610 F.3d at 4 (quoting Onwuamaegbu v. Gonzales, 470 F.3d 405, 412 (1st Cir.2006)). In the end, then, “we will vacate the decision below if the [immigration court] committed a material error of law or failed to articulate its reasoning adequate*43ly.” Id. at 5. Here, we will apply this standard to Romer’s two arguments: that the time and number restrictions on his motion to reopen should be equitably tolled, and that imposition of the ten-year adjustment-of-status bar was inappropriate because his failure to timely depart was not voluntary.
First, Romer asks us to find that equitable considerations allow him to escape the time and number restrictions that doomed his motion to reopen. Generally speaking, “[t]he motion to reopen is a procedural device [that] selves to ensure that aliens get a fair chance to have their claims heard.” Id. (quoting Kucana, 130 S.Ct. at 837) (internal quotation marks omitted). But motions to reopen come with significant limitations: in the usual case, a party may file only one such motion, 8 C.F.R. § 1003.23(b)(1); 8 U.S.C. § 1229a(c)(7)(A), and must do so within 90 days of the final removal order, 8 U.S.C. § 1229a(c)(7)(C)(i).
In general, equitable principles may apply to ease the strict application of procedural limitations. Bay State HMO Management, Inc. v. Tingley Systems, Inc., 181 F.3d 174, 182 (1st Cir.1999) (“Equity demands that we not allow ... draconian result[s] to turn on ... procedural quirk[s].”). These principles’ application in the immigration context is not always so clear-cut; for example, the BIA has held that ten-year adjustment-of-status — bars the principle we discuss next are not subject to equitable easing. See In re Zmijewska, 24 I. & N. Dec. 87, 93 (B.I.A.2007). But in the case of subsequent, untimely-filed motions to reopen, at least one other circuit has held that equitable tolling may apply to allow such a motion in the proper case. See Iavorski v. INS, 232 F.3d 124, 134 (2d Cir.2000).
Romer asks us to join the Second Circuit and apply equitable tolling here, but we need not go so far. We have previously declined to decide whether time and number restrictions on motions to reopen may be equitably tolled, see Neves, 613 F.3d at 35-36; Chedid v. Holder, 573 F.3d 33, 37 (1st Cir.2009), and do so again today. We conclude instead that the IJ produced (and the BIA silently endorsed) a deficient decision that too casually glossed over the question whether tolling might apply.
In rejecting Romer’s request for relief from the time and number restrictions on motions to reopen, the IJ’s decision lacks any equitable tolling analysis. Where Romer cited tolling cases and discussed how they might apply to his situation, the IJ only referred vaguely to Romer’s “looking for ways or alternatives to circumvent” his obligation to depart, and his “disregarding deadlines and orders.” These vague references ignore Romer’s argument, ignore arguably applicable law, and cross the line from merely deficient to plainly arbitrary. See Aponte, 610 F.3d at 4; see also Le Bin Zhu v. Holder, 622 F.3d 87, 91 (1st Cir.2010) (abuse of discretion includes “exercising] judgment in an arbitrary ... way”). Under these circumstances, we think remand is necessary. On remand, the IJ should consider whether equitable tolling is available to Romer on his motion to reopen.6
*44Second, Romer asks us to find that attorney misadviee rendered his failure to timely depart involuntary, thus saving him from the ten-year adjustment-of-status bar. The immigration code plainly bars an alien who “voluntarily fails to depart” from adjusting his immigration status for the next ten years. 8 U.S.C. § 1229c(d)(l). Earlier versions of section 1229c allowed immigrants to escape the ten-year bar in cases involving “exceptional circumstances,” but Congress amended the statute in 1996 to remove that allowance and include instead the word “voluntarily.” See Zmijewska, 24 I. & N. Dec. at 90-91. We have already mentioned above that the bar is not subject to equitable easing, id. at 93, so the only way Romer can avoid application of the ten-year bar is if his failure to depart was not “voluntary.”7 Id.
Again, though, rather than going on to analyze the voluntariness of Romer’s failure to depart, we instead conclude that the IJ’s decision so inadequately deals with this argument that it constitutes an abuse of discretion.
In imposing the ten-year bar against Romer, the IJ offered nothing approaching reasoning. Again, Romer cited law that could plausibly afford him relief. Again, the IJ ignored that law and said she was “not convinced of the excuses provided by the respondent.” And again, the IJ’s failure to engage with Romer’s arguments crossed the line from deficient to arbitrary. See Aponte, 610 F.3d at 4. On remand, the IJ should consider whether Romer’s remaining in the country on counsel’s erroneous and bad-faith advice (a factual premise the IJ is free to accept or reject on consideration of the evidence) rendered his noncompliance involuntary.8
The IJ and BIA committed an abuse of discretion by failing to address adequately Romer’s potentially winning arguments.9 For this reason, we grant the petition for review and remand for consideration of (1) whether equitable principles mean Rom-er’s third motion to reopen is properly before the immigration courts, and (2) whether Romer is indeed subject to the ten-year bar on status adjustments because he remained in the country voluntarily. So ordered.
