SUMMARY ORDER

UPON DUE CONSIDERATION, IT IS HEREBY ORDERED, ADJUDGED, AND DECREED that the judgment is AFFIRMED.

Appellant Panayota Bletas, proceeding pro se, appeals from the district court’s judgment granting Subway International B.V.’s (“SIBV”) application for confirmation of an arbitration award. Ms. Bletas raises three principal arguments: (1) the district court did not have personal jurisdiction over her because she did not receive proper service of process; (2) the arbitrator’s award was barred by res judi-cata; and (8) the arbitration award cannot be confirmed because it violated public policy. We assume the parties’ familiarity with the underlying facts, the procedural history, and the issues on appeal.

It is well settled that lack of personal jurisdiction is a defense that can be waived by failure to assert it seasonably or by submission through conduct. See Neirbo Co. v. Bethlehem Shipbuilding Corp., 308 U.S. 165, 168, 60 S.Ct. 153, 84 L.Ed. 167 (1939). We review a district court’s ruling that a defendant waived or forfeited a personal jurisdiction defense for abuse of discretion. See Hamilton v. Atlas Turner, Inc., 197 F.3d 58, 60 (2d Cir. 1999). The district court did not abuse its discretion in concluding that Ms. Bletas forfeited her improper service defense by participating in a settlement conference and filing multiple motions without mentioning the defense. 1 See Datskow v. Teledyne, Inc., 899 F.2d 1298, 1303 (2d Cir. 1990); Hamilton, 197 F.3d at 61-62.

We also reject Ms. Bletas’s argument that a prior arbitration award precluded the award involved in this case under the doctrine of res judicata. The prior arbitration award cited by Ms. Bletas cannot preclude the award at issue in this case because the claims asserted in this arbitration could not have been raised in the prior one. See Allen v. McCurry, 449 U.S. 90, 94, 101 S.Ct. 411, 66 L.Ed.2d 308 (1980). As the district court ably explained, the two arbitration proceedings involved separate franchise agreements that, per the terms of the agreements, could not have been arbitrated in the same proceeding.

Finally, with respect to the district court’s confirmation of the arbitration award, we review findings of fact for clear error and conclusions of law de novo. See Idea Nuova, Inc. v. GM Licensing Grp., *84 Inc., 617 F.3d 177, 180 (2d Cir. 2010). Upon, such review, we conclude that Ms. Bletas’s appeal is without merit substantially for the reasons articulated by the district court in its order granting SIBV’s application.

We decline to consider the numerous arguments that Ms. Bletas raises for the first time on appeal. See Singleton v. Wulff, 428 U.S. 106, 120-21, 96 S.Ct. 2868, 49 L.Ed.2d 826 (1976); Virgilio v. City of N.Y., 407 F.3d 105, 116 (2d Cir. 2005). We have considered all of Ms. Bletas’s arguments that are properly before us and find them to be without merit. Accordingly, the judgment of the district court is hereby AFFIRMED.
