reasoning was undermined by the Supreme Court’s subsequent retroactivity cases, such as Landgraf v. USI Film Prods., 511 U.S. 244, 114 S.Ct. 1483, 128 L.Ed.2d 229 (1994), and St. Cyr, 533 U.S. 289, 121 S.Ct. 2271, 150 L.Ed.2d 347. While we have recently sug gested that, in light of St. Cyr, Buitrago-Cues-ta's holding may perhaps have to be read not to apply to aliens who pleaded guilty before the enactment of the five-year bar, see, e.g., Theodoropoulos v.

Ashcroft, 253 F.3d 811, 814 (5th Cir.2001) (same) with Cunningham v. Attorney General, 335 F.3d 1262, 1267 (11th Cir.2003) (per curiam) (<HOLDING>); Alanis-Bustamante v. Reno, 201 F.3d 1303,
holding in the iirira context that the combination of service of the order to show cause and the issuance of a detainer notice sufficed to begin the proceedings holding that for purposes of the iirira proceedings commence only upon the inss filing of a notice to appear with the immigration court holding in the iirira context that service of the notice to appear was on the facts of that case sufficient to start proceedings holding that the burden is on the plaintiff to allege facts sufficient to establish jurisdiction holding that defendant failed to plead sufficient facts and instructing the trial court to dismiss the plaintiff from the case
