These petitions for writs of mandamus ask us to order the United States District Court for the Middle District of Louisiana to vacate its transfer to the Southern District of Indiana. The petitions were filed more than three months after the transfer and after proceedings had begun in the transferee court. We deny the petitions.
I.
Red Barn Motors, Incorporated (“Red Barn”), is a car dealership that, in 2011, entered into an agreement with Dealer Services Corporation (“DSC”) for DSC to finance Red Barn’s purchase of vehicles at auction. According to Red Barn’s complaint, when it would buy a vehicle at auction, sometimes six to eight weeks would elapse before the auction house would obtain the title and transfer it to DSC. Red Barn contends that DSC would not pay the auction house until DSC received the title but would charge interest and fees starting from when Red Barn made the purchase, weeks before DSC transferred the funds to the auction house.
In March 2013, Red Barn stopped making payments to DSC on its line of credit, whereupon DSC began seizing some of Red Barn’s assets. In April, Red Barn delivered about a dozen vehicles to Louisiana’s First Choice Auto Auction, L.L.C. (“First Choice”), to sell, but First Choice delivered them to DSC. Red Barn declared bankruptcy that month. At some point, DSC was absorbed by NextGear Capital, Inc. (“NextGear”).

Red Barn sued NextGear and First Choice in the Middle District of Louisiana, claiming breach of contract and unjust enrichment by NextGear and conversion by both defendants. NextGear moved to transfer the case to the Southern District of Indiana under 28 U.S.C. § 1404(a).1 NextGear attached to its motion a copy of the promissory note that Red Barn had tendered to DSC, which stated that Red Barn consented to personal jurisdiction and venue in the state and federal courts of Marion and Hamilton Counties, Indiana, and that any claims by Red Barn against DSC arising out of the promissory note would be brought in those courts.
First Choice and Red Barn opposed the transfer. Red Barn contended that this was an exceptional case in which a forum-selection clause should not be enforced; it also alleged that NextGear had intended to breach the promissory note when signing it and had therefore procured the contract by fraud. First Choice, meanwhile, contended that venue would be.improper in Indiana because First Choice was a Texas company with its principal place of business in Louisiana, and all of the events relating to the lawsuit took place in Louisiana. Additionally, First Choice stated that the forum-selection clause could not be applied against it because it was not a signatory. .
NextGear responded, in relevant part, that First Choice could be bound to the forum-selection clause under the doctrine of direct-benefits estoppel, which in some circumstances can make a forum-selection clause effective against a nonsignatory.2 *483NextGear contended that First Choice was aware of the financing agreement because the purchase forms executed by First Choice and Red Barn noted DSC as the financer. Additionally, NextGear asserted that First Choice benefited from the agreement because it allowed Red Barn to buy First Choice’s vehicles.
The court held a hearing on the transfer motion in July 2014 and granted it in September 2014. The court reasoned that First Choice had knowingly exploited the contract. Because § 1404(a) allows transfer to a venue to which the parties have consented, the court held that the case could be transferred to the Southern District of Indiana even though that court probably would not otherwise have personal jurisdiction over First Choice. The court then conducted the rest of the transfer analysis, ultimately concluding that this was not an exceptional case in which a forum-selection clause should not be enforced. The clerk electronically transferred the case to the Southern District of Indiana in September.
Red Barn waited until January 2015 to file the instant mandamus petition, and' First Choice followed with its own petition in February. The case is pending in Indiana, that court having temporarily stayed proceedings awaiting the outcome of these petitions.
Both petitions claim that the district court erred in enforcing the forum-selection clause against First Choice, a nonsig-natory to the contract containing the clause. They contend First Choice received no benefits under the contract and had no knowledge of its terms and that applying the clause against it through direct-benefits estoppel was therefore improper.
Although NextGear did not initially question our jurisdiction to order mandamus, we have an independent obligation to determine our own jurisdiction, even if the question is not raised or disputed by the parties. See, e.g., Sandy Creek Investors, Ltd. v. City of Jonestown, Tex., 325 F.3d 623, 626 (5th Cir.2003). We ordered supplemental briefing on the question whether this court has jurisdiction to issue the writ. Because petitioners did not diligently seek review of the transfer in this court, we deny the petitions.
III.
The All Writs Act, 28 U.S.C. § 1651, empowers us to issue writs of mandamus, but that statutory authority does not itself confer jurisdiction. Regions Bank of La. v. Rivet, 224 F.3d 483, 493 (5th Cir.2000). We can issue a writ of mandamus only if we have jurisdiction. See United States v. Denedo, 556 U.S. 904, 911, 129 S.Ct. 2213, 173 L.Ed.2d 1235 (2009). “The power conferred on [the circuit courts of appeals] by § 1651 is limited to their appellate jurisdiction.” 3 Our jurisdiction for mandamus “is not confined to the issuance of writs in aid of a jurisdiction already acquired on appeal but extends to those cases which are within [our] appellate jurisdiction although no appeal has been perfected.” Roche v. Evaporated Milk Ass’n, 319 U.S. 21, 25, 63 S.Ct. 938, 87 L.Ed. 1185 (1943).
The jurisdiction of the courts of appeals extends to “appeals from all final decisions of the district courts of the United States.” 28 U.S.C. § 1291. Generally, however, such an appeal can be taken only by “the *484court of appeals for the circuit embracing the district,” 28 U.S.C. § 1294(1), so we can take appeals only from district courts in Texas, Mississippi, and Louisiana and certain administrative agencies. 28 U.S.C. § 41. This case began in a Louisiana district court but has been transferred to a district court in the Seventh Circuit, in which any appeal would lie.
The Louisiana court, meanwhile, has lost its jurisdiction. In re Sw. Mobile Homes, Inc., 317 F.2d 65, 66 (5th Cir.1963). It is no longer capable of making a final decision that would be appealed to us. No party contends that the transfer order is an immediately reviewable decision. See In re Rolls Royce Corp., 775 F.3d 671, 676 (5th Cir.2014). This is not just a case in which no appeal to the Fifth Circuit has been perfected; instead, it is a proceeding in which no appeal to this court can be taken, short of the purely speculative possibility that the Indiana court transfers it back.
In Southwestern Mobile Homes, 317 F.2d at 66, we recognized it was “extremely doubtful” that we had authority over a case once it was transferred to a district court in a different circuit. It seems uncontroversial in this situation that a transfer to another circuit removes the case from our jurisdiction, and numerous circuits have stated that rule plainly.4
Although we lack jurisdiction to order the transferee district court to return the case,5 several circuits, where appropriate, have endorsed the method of directing the transferor district court to request that the transferee district court return the case.6 In Southwestern Mobile Homes, we recognized that using mandamus to undo a completed inter-circuit transfer risks “provoking] a possible conflict between the Circuits”; thus, if we even have the power to reverse such a transfer, we should exercise it only if faced with “a very extreme case.” 317 F.2d at 66-67. Here, that risk is tempered because the transferee district court has expressly stayed all proceedings pending this panel’s decision.
Despite the potential availability of this remedy, mandamus is not warrant*485ed here.7 A court of appeals should consider directing that the transferor district court request return of the case only where the case has been transferred “despite the petitioner’s diligence.”8 Petitioners did not timely seek review of the transfer order. Although they could not have done so before the case was transferred, they offer no explanation for waiting more than three months before filing any petition for review. Petitioners have not been diligent in seeking review of the transfer.9
The petitions for writs of mandamus are DENIED.
