   MEMORANDUM

Humberto Vallin petitions for review of the Board of Immigration Appeals’ termination of his conditional permanent resident status and concomitant denial of permanent residence. See 8 U.S.C. § 1186a(c)(2), (4). We deny the petition.

(1) Vallin first asserts that the Immigration and Naturalization Service should have been estopped from claiming that he was not a permanent resident. However, he has not shown that the INS engaged in affirmative misconduct rather than, at most, mere negligence. See INS v. Miranda, 459 U.S. 14, 17-19, 103 S.Ct. 281, 283-84, 74 L.Ed.2d 12 (1982) (per curiam); Socop-Gonzalez v. INS, 272 F.3d 1176, 1184 (9th Cir.2001) (en banc). No deliberate he or pattern of false promises has been spelled out. See Mukherjee v. INS, 793 F.2d 1006, 1009 (9th Cir.1986). Moreover, Vallin fails to show that a serious injustice would result or that the public interest would not suffer unduly if the INS were estopped. Id. at 1008-09. Thus, there can be no estoppel.

(2) Next, Vallin asserts that laches should bar the INS because it took too long—eight years—to proceed. But, laches has been consistently rejected as a bar to government action. See Costello v. United States, 365 U.S. 265, 281, 81 S.Ct. 534, 542—43, 5 L.Ed.2d 551 (1961); United States v. Ruby Co., 588 F.2d 697, 705 n. 10 (9th Cir.1978). In any event, mere delay will not give rise to laches, and Vallin has failed to spell out any right that the INS deprived him of when it did not act more quickly.

(3) In his brief before us, Vallin alludes to a claimed due process violation by the BIA, but does not support his allusions with legal argument or citations. Thus, the issue is not properly before us. See Resorts Int’l, Inc. v. Lowenschuss (In re Lowenschuss), 67 F.3d 1394, 1402 (9th Cir.1995); Int’l Union of Bricklayers Local 20 v. Martin Jaska, Inc., 752 F.2d 1401, 1404-05 (9th Cir.1985); see also Smith v. Marsh, 194 F.3d 1045, 1052 (9th Cir.1999).

(4) Finally, Vallin’s claim of ineffective assistance of counsel is not properly before us because he failed to exhaust his administrative remedies by presenting the claim to the BIA. See 8 U.S.C. § 1252(d)(1); Liu v. Waters, 55 F.3d 421, 424 (9th Cir.1995); Arreaza-Cruz v. INS, 39 F.3d 909, 912 (9th Cir.1994); Roque-Carranza v. INS, 778 F.2d 1373, 1373—74 (9th Cir.1985); see also Rashtabadi v. INS, 23 F.3d 1562, 1567 (9th Cir.1994).

Petition DENIED.

      . See Costello, 365 U.S. at 282-84, 81 S.Ct. at 543-44 (twenly-seven year delay in commencement of denaturalization proceeding would not be enough by itself); see also Beaty v. Selinger (In re Beaty), 306 F.3d 914, 927-28 (9th Cir.2002).
