ORDER

KATHERINE P. NELSON, Magistrate Judge.

This action is before the Court on the Plaintiffs' Second Motion for Leave of Court to Amend the Original Complaint and Add an Additional Defendant, Tidy Staffing Solutions, Ltd. (Doc. 20). The Plaintiffs represent that counsel for the Defendant has been contacted regarding the substance of the motion and "has no objection" to the Court granting it. Nevertheless, upon consideration, the Court finds the motion is due to be DENIED.

This action was removed to this Court from Alabama state court under 28 U.S.C. § 1441(a), with diversity of citizenship under 28 U.S.C. § 1332(a) being the sole basis alleged for original jurisdiction. (See Doc. 1). Per the Defendant's allegations in the notice of removal, which the Plaintiffs have not challenged, the natural person Plaintiffs are citizens of Alabama, while the Defendant corporation is a Florida citizen (as it was incorporated in that state and has its principal place of business there, see 28 U.S.C. § 1332(c)(1)). (Doc. 1 at 3-4, ¶ 7).

Though brought as a motion to amend the complaint under Federal Rule of Civil Procedure 15(a)(2), the present motion is in substance a motion for joinder under Federal Rule of Civil Procedure 20, as it seeks to add an additional defendant, Tidy Staffing.1 See Ingram v. CSX Transp., Inc., 146 F.3d 858, 862 (11th Cir. 1998) ("Although Ingram styled her motion to add the City as a motion to amend her complaint pursuant to Fed. R. Civ. P. 15(a), this amendment amounted to a joinder, pursuant to Fed. R. Civ. P. 20[,]" where amendment solely sought to add an additional defendant.). Thus, "in determining whether to grant [the Plaintiffs'] motion, the [C]ourt [must] consider[] 28 U.S.C.A. § 1447(e), which provides: `If after removal the plaintiff seeks to join additional defendants whose joinder would destroy subject matter jurisdiction, the court may deny joinder, or permit joinder and remand the action to the State court.'" Id.

The Plaintiffs allege that Tidy Staffing is "a corporate entity located in the State of Ohio but doing business on a regular basis in Baldwin County, Alabama . . ." (Id. at 3). This allegation is insufficient to establish Tidy Staffing's citizenship for purposes of § 1332(a). If Tidy Staffing is indeed a corporation, as the Plaintiffs allege, then they must allege "every State and foreign state by which it has been incorporated and []the State or foreign state where it has its principal place of business . . ." 28 U.S.C. § 1332(c)(1). The Plaintiffs have alleged neither, instead identifying only states where it is allegedly "located" or "does business."

However, the use of the identifier "Ltd.," rather than "Inc.," suggests that Tidy Staffing is in fact an unincorporated entity.2 The rule for diversity jurisdiction is "that the citizenship of an artificial, unincorporated entity generally depends on the citizenship of all the members composing the organization." Rolling Greens, MHP, L.P. v. Comcast SCH Holdings, L.L.C., 374 F.3d 1020, 1021 (11th Cir. 2004) (per curiam) (citing Carden v. Arkoma Assocs., 494 U.S. 185, 195-96 (1990)). See also Americold Realty Trust v. Conagra Foods, Inc., 136 S.Ct. 1012, 1016 (2016) ("So long as . . . an entity is unincorporated, we apply our `oft-repeated rule' that it possesses the citizenship of all its members." (reaffirming Carden)). As such, "to sufficiently allege the citizenships of . . . unincorporated business entities, a party must list the citizenships of all the members" of those entities. Rolling Greens, 374 F.3d at 1022. Accord Mallory & Evans Contractors & Eng'rs, LLC v. Tuskegee Univ., 663 F.3d 1304, 1305 (11th Cir. 2011) (per curiam). The Plaintiffs have not alleged this information either.

Under § 1447(e), a district court "ha[s] no discretion to add [a non-diverse party] as a defendant, retain jurisdiction and decide the case on the merits." Ingram, 146 F.3d at 862. Rather, when § 1447(e) applies, a district court has "only two options: (1) deny joinder; or (2) permit joinder and remand [the] case to state court." Id. Because the Plaintiffs have not provided sufficient information to determine the citizenship of proposed additional defendant Tidy Staffing for purposes of § 1332(a), the Court is unable to ascertain whether the joinder of Tidy Staffing will destroy diversity jurisdiction.3 Accordingly, it is ORDERED that the Plaintiffs' Second Motion for Leave of Court to Amend the Original Complaint and Add an Additional Defendant, Tidy Staffing Solutions, Ltd. (Doc. 20), construed as a motion to join Tidy Staffing under Federal Rule of Civil Procedure 20, is DENIED.

DONE and ORDERED.
