Concurrence by Judge GRABER

OPINION

In Sosa v. Alvarez-Machain, 542 U.S. 692 , 124 S.Ct. 2739 , 159 L.Ed.2d 718 (2004), the Supreme Court held that the foreign country exception to the Federal . Tort Claims Act (“FTCA”) “bars all claims based on any injury suffered in a foreign country.” Id. at 712 , 124 S.Ct. 2739 . The Court left unanswered, however, the issue *1058 currently before us: How to determine where an injury is “suffered.” We hold that an injury is suffered where the harm first “impinge[s]” upon the body, even if it is later diagnosed elsewhere. See Restatement (First) Conflict of Laws § 377, n.l (1934).

Applying that test to the facts of this case, we conclude that the foreign country exception bars plaintiffs’ claims. S.H., the daughter of William and Chantal Holt, was born prematurely while the family was stationed at a United States Air Force (“USAF”) base in Spain. As a consequence of her premature birth, S.H. sustained a permanent injury to the white matter of her brain; she was diagnosed as suffering from cerebral palsy after the family returned to the United States. The Holts filed suit against the United States, contending that officials at a USAF base in California negligently approved the family’s request for command-sponsored travel to a base in Spain ill-equipped to deal with Mrs. Holt’s medical needs. They further argue that S.H.’s injury — the cerebral palsy diagnosis — first occurred upon their return to the United States. At trial, the district court agreed that the injury occurred in South Carolina and awarded damages of $10,409,700. Although we are sympathetic to the plaintiffs’ situation, we agree with the United States that the injury at issue was suffered in Spain. We exercise jurisdiction under 28 U.S.C. § 1291 and reverse.

A

Mr. Holt is a Master Sergeant in the USAF. He and his wife have four children. In 2004, when the family was stationed at Edwards Air Force Base in California, Mr. Holt was informed that he was being transferred to the USAF Air Base at Rota Naval Station in Spain. Shortly thereafter, a pregnancy test at the Edwards Air Force Base medical clinic confirmed that Mrs. Holt was pregnant with their third child.

After learning he was to be transferred overseas, Mr. Holt requested command-sponsored travel for his family. To obtain approval for this program, family members must be screened to ensure that the overseas base is capable of addressing their medical needs. Dr. Richard Stahlman, chief of the medical staff at Edwards Air Force Base, approved the Holt family’s command-sponsored travel to Spain. The district court found that Dr. Stahlman knew Mrs. Holt was pregnant and had experienced two prior preterm deliveries and a miscarriage at the time he cleared her for overseas travel.

In March 2005, when Mrs. Holt was approximately twenty weeks pregnant, the family relocated to Spain. There, Mrs. Holt' was treated by Dr. Dennis Szurkus, a specialist in obstetrics and gynecology at Naval Hospital Rota. During, an ultrasound appointment on May 11, 2005, Dr. Szurkus determined that Mrs. Holt was exhibiting signs of preterm labor and had her transferred by ambulance to an off-base hospital — Puerto Real Hospital — where she underwent an emergency cesarean section. S.H. was born on May 12, at approximately 31 weeks gestation. She had difficulty eating and breathing and was kept in the neonatal intensive care unit for seventeen days.

In the months following S.H.’s birth, the Holts saw several doctors in Spain regarding her medical issues and expressed concern that S.H. was not developing like her two older siblings, both of whom were also born preterm. Doctors told the Holts that S.H. had strabismus, poor head control, low tone in her abdominal muscles, and significant motor and developmental de *1059 lays. S.H. also experienced seizure-like symptoms, for which she was prescribed phenobarbital. When she was approximately five months old, S.H. underwent an MRI, which showed periventricular leuko-malacia, an injury to the white matter of her brain.

At around nine months of age, S.H. was evaluated by a neurologist, Dr. Lisa Smith, who found that S.H. had abnormally brisk reflexes and a mild increase in dynamic tone in her lower extremities. Dr. Smith did not rule out cerebral palsy at that time but declined to render a diagnosis. Two other doctors in Spain did conclude that S.H. had cerebral palsy. 1

The family returned to the United States in mid-2006. Late that year, S.H. was diagnosed with tetraplegia of all four extremities. At the age of two, while living in South Carolina, S.H. was definitively diagnosed with cerebral palsy. It is undisputed that S.H.’s premature birth was the cause of her cerebral palsy.

B

In- June 2006, while the Holts were still in Spain, they filed an administrative claim seeking damages from the government for S.H.’s “catastrophic neurological injuries, seizures, learning deficits, physical limitations,” and “cerebral palsy.” They alleged that these injuries resulted from the negligent approval of Mrs. Holt’s command-sponsored travel overseas. The administrative claim was denied.

Having exhausted administrative remedies, the Holts filed the instant action in district court. The government unsuccessfully moved for summary judgment, contending that the FTCA’s foreign country exception barred the Holts’ medical malpractice claims. Following a bench trial, the court awarded the Holts $10,409,700 in damages. The government filed a motion to alter or amend the judgment under Fed. R. Civ. P. 59(e). The court granted the motion in part but ultimately declined to alter the damages award. The government timely appealed the amended judgment and all related interlocutory orders.

We review a district court’s findings of fact following a bench trial for clear error. Kohler v. Presidio Int'l, Inc., 782 F.3d 1064, 1068 (9th Cir. 2015). However, “[wjhether the United States is immune from liability in a FTCA action is a question of federal law subject to de novo review.” Montes v. United States, 37 F.3d 1347, 1351 (9th Cir. 1994) (italics omitted).

The FTCA generally waives the United States’ sovereign immunity from suits in tort, “rendering] the Government liable in tort as a private individual would be under like circumstances.” Richards v. United States, 369 U.S. 1, 6 , 82 S.Ct. 585 , 7 L.Ed.2d 492 (1962); see also 28 U.S.C. § 2674 . But that waiver is subject to certain exceptions. See generally 28 U.S.C. § 2680 . Under the foreign country exception, the FTCA’s waiver of immunity does not apply to “[a]ny claim arising in a foreign country.” Id. § 2680(k).

In Sosa , the Supreme Court held that the foreign country exception “bars all claims based on any injury suffered in a foreign country, regardless of where the tortious act or omission occurred.” 542 U.S. at 712 , 124 S.Ct. 2739 . The Court noted that the foreign country exception *1060 codified Congress’ “unwilling[ness] to subject the United States to liabilities depending upon the laws of a foreign power.” Id. at 707 , 124 S.Ct. 2739 (alteration in original) (quoting United States v. Spelar, 338 U.S. 217, 221 , 70 S.Ct. 10 , 94 L.Ed. 3 (1949)). At the time the FTCA was passed, “the dominant principle in choice-of-law analysis for tort cases was lex loci delicti: courts generally applied the law of the place where the injury occurred.” Id. at 705, 124 S.Ct. 2739 . Accordingly, the Court concluded that Congress likely intended the phrase “arising in” to have the same meaning in § 2680(k) as it did in state choice-of-law statutes: that is, to “express the position that a claim arises where the harm occurs.” Id. at 711, 124 S.Ct. 2739 . 2

The question at the center of this appeal is where S.H.’s injury was “suffered” for the purposes of the foreign country exception. Id. at 712 , 124 S.Ct. 2739 . The Sosa opinion offers various formulations of lex loci delicti, but provides little guidance on this specific issue. See, e.g., id. at 705, 124 S.Ct. 2739 (claim arises “where the last act necessary to establish liability occurred; 1.e., the jurisdiction in which injury was received” (quoting John W. Ester, Borrowing Statutes of Limitation & Conflict of Laws, 15 U. Fla. L. Rev. 33 , 47 (1962))); id. at 706 , 124 S.Ct. 2739 (“the place where the harmful force takes effect upon the body” (quoting Restatement (First) of Conflict of Laws § 377, n.l (1934) (emphasis omitted))). In the ordinary case, an injury will be experienced in the same place it is inflicted, thereby obviating the need for further analysis. See, e.g., id. at 698, 124 S.Ct. 2739 (seeking damages for false arrest in Mexico). However, the inquiry becomes more complicated when, as in this case, plaintiffs allege injuries manifesting after the initial infliction of harm.

The district court concluded that state accrual law should determine where an injury is suffered. Relying on California law, it held that S.H.’s cerebral palsy occurred in the United States because it was not until the Holts arrived in South Carolina that doctors could identify S.H.’s symptoms as cerebral palsy. But as we have previously noted, “[qjuestions of interpretation under the [FTCA’s] exclusion provisions are controlled by federal law.” Ramirez v. United States, 567 F.2d 854, 856 (9th Cir. 1977); accord United States v. Neustadt, 366 U.S. 696, 706 , 81 S.Ct. 1294 , 6 L.Ed.2d 614 (1961) (“[Wjhether [a] claim is outside the intended scope of the Federal Tort Claims Act ... depends solely upon what Congress meant by the language it used.... ”). The district court acknowledged this principle as a general matter but concluded that because California law governed the United States’ liability under 28 U.S.C. § 1346 (b)(1), it also determined where the Holts’ claims arose. However, § 2680(k) states that § 1346(b) *1061 “shall not apply to” any claim falling within the foreign country exception.

The district court also failed to recognize that the question of when a claim accrues for statute of limitations purposes is analytically distinct from the question of where a claim arises under the foreign country exception. See Manemann v. United States, 381 F.2d 704, 705 (10th Cir. 1967) (“[I]n the case at bar we are not concerned with either the time or place of an accrued cause of action for the purpose of applying a statute of limitations or a principle of conflict of law. We are concerned only as to whether appellant’s claim arose in a foreign country within the contemplation of section 2680(k).... ”); In re Joint E. & S. Dist. Asbestos Litig., 721 F.Supp. 433, 435 (E.D.N.Y. & S.D.N.Y. 1988) (stating that the “last event” required to establish liability “is not necessarily plaintiffs discovery of his illness; so to hold would be to confuse the beginning of plaintiffs cause of action with the beginning of its end, i.e., with the starting of the statute of limitations” (internal quotation marks omitted)). There may be some overlap in the standards applied to these questions. See United States v. Kubrick, 444 U.S. 111, 120 , 100 S.Ct. 352 , 62 L.Ed.2d 259 (1979) (recognizing that “the general rule under the [FTCA] has been that a tort claim accrues at the time of the plaintiffs injury”). But the statute of limitations inquiry is concerned with a plaintiffs knowledge, see id. at 118-24 , 100 S.Ct. 352 , to ensure that a limitations period does not lapse before a reasonably diligent plaintiff is aware of her injury, see In re Joint E. & S. Dist. Asbestos Litig., 721 F.Supp. at 435 (equating “plaintiffs discovery of his illness” with the “starting of the statute of limitations”). In deciding where a claim arises under the foreign country exception, however, we are not concerned with the possibility of a blameless plaintiff losing a claim through delay. Thus, we ask only where “the last act necessary to establish liability occurred,” Sosa, 542 U.S. at 705 , 124 S.Ct. 2739 (internal quotation marks omitted), without taking into account what the plaintiff knew or did not know. 3

To determine where the Holts’ claims arose for the purposes of the foreign country exception, we must therefore look to governing choice-of-law principles at the time Congress enacted the FTCA. And, as the Supreme Court held in Sosa , we must apply lex loci delicti. Id. The Restatement (First) of Conflict of Laws, upon which the Supreme Court relied in Sosa , provides that “[t]he place of wrong is ... where the last event necessary to make an actor liable for an alleged tort takes place.” § 377. The Restatement illustrates application of this rule when an individual “sustains bodily harm” as follows:

Id. § 377, n.1. Thus, an injury “occurs” where it is first suffered, even if a negligent act later results in further or more *1062 serious harm. Accord Williams v. Gyrus ACMI, Inc., 790 F.Supp.2d 410, 415 (D. Md. 2011) (holding that plaintiffs injury occurred for purposes of lex loci delicti at the time shim was left in her body, “even if she did not begin to experience pain or other symptoms from the shim’s presence until she relocated” to another state).

It is undisputed that S.H.’s cerebral palsy resulted from the brain injury she sustained in Spain as a consequence of her premature birth. The district court held that the Holts’ claims arose in the United States because that is where S.H.’s cerebral palsy definitively manifested itself. In reaching that determination, the court distinguished between S.H.’s brain injury and her cerebral palsy diagnosis, reasoning that because plaintiffs were suing to recover for the latter harm, and cerebral palsy is not a disease but rather a collection of symptoms, plaintiffs’ claims could not have arisen prior to those symptoms being present and diagnosable. But S.H.’s premature birth caused appreciable injury while the Holts were in Spain, even if cerebral palsy was not definitively diagnosed in that country. Under lex loci de-licti, as it was interpreted at the time of the FTCA’s passage, the fact that a plaintiff suffers some “other loss” in a different jurisdiction is “immaterial.” Restatement (First) Conflict of Laws § 377, n.1. “The question is only where did the force impinge upon [her] body.” Id. The undisputed facts of this case indicate that the force — the brain injury S.H. suffered at or near the time of her birth — impinged upon her body in Spain; thus, that is where the Holts’ claims arose. See Sosa, 542 U.S. at 705-06 , 124 S.Ct. 2739 . 4

Our conclusion is consistent with the application of the foreign country exception by other federal courts. In Thompson v. Peace Corps, 159 F.Supp.3d 56 (D.D.C. 2016), the court held that the foreign country exception barred the plaintiffs FTCA claims, which were based on injuries she sustained as a result of taking an antimalarial drug in Burkina Faso. Id. at 61 . The court reasoned that although the plaintiff “complain[ed] of continuing side effects after her return home,” as well as “a permanent brain injury,” the court lacked jurisdiction because the “claims based on those injuries arose out of the administration of mefloquine in Burkina Faso.” Id. at 58, 61 . Similarly, the District of Columbia Circuit has twice held that a district court lacked jurisdiction over a plaintiffs claims for emotional or economic injuries occurring in the United States because those injuries were derivative of harm suffered abroad by the plaintiffs’ spouses. See Gross v. United States, 771 F.3d 10, 13 (D.C. Cir. 2014) (holding that foreign country exception applied because *1063 wife’s economic injuries in the United States were derivative of injuries husband suffered as a result of imprisonment in Cuba); Harbury v. Hayden, 522 F.3d 413, 423 (D.C. Cir. 2008) (holding that foreign country exception applied to claims for emotional injuries that wife suffered in United States but that resulted from physical abuse and death of husband in Guatemala). In both cases, the court expressed concern that plaintiffs would be able to “plead around the FTCA’s foreign-country exception simply by claiming injuries ... that are derivative of the foreign-country injuries at the root of the complaint.” Harbury, 522 F.3d at 423 .

Like the injuries alleged in these cases, S.H.’s cerebral palsy is derivative of the harm she sustained at birth. As the Holts recognize, cerebral palsy is not itself a disease, but rather a group of non-progressive motor conditions. It is therefore a description of symptoms manifesting from S.H.’s brain injury, rather than a separate, compensable harm. Moreover, to hold that the Holts’ claims did not arise until cerebral palsy could be definitively diagnosed would enable plaintiffs in similar circumstances to avoid application of the foreign country exception, either by pleading their injuries in a particular way or by relocating to the United States before obtaining a diagnosis. Cf. Sosa, 542 U.S. at 702-03 , 124 S.Ct. 2739 (rejecting idea that “allegations of negligent medical care ... can ... be repackaged as headquarters claims based on ... the offering of bad advice” in the United States, even though harm is suffered overseas, because the practice would “swallow the foreign country exception whole” (citations omitted)); Harbury, 522 F.3d at 423 (prohibiting plaintiffs from “plead[ing] around” the foreign country exception by claiming domestic injuries “that are derivative of the foreign-country injuries at the root of the complaint”). Jurisdiction under the FTCA cannot turn on whether the Holts framed their suit as seeking damages for S.H.’s cerebral palsy or the brain injury she sustained at birth.

Ill

Because the Holts’ claims against the United States arose in Spain, the FTCA’s foreign country exception bars their suit. Accordingly, the district court’s order is VACATED, and we REMAND the case with instructions to dismiss for lack of subject matter jurisdiction. 5 The parties shall bear their own costs on appeal.

. Those doctors were Dr. Paul Shales, a developmental pediatrician at the Educational, Developmental and Intervention Services Clinic at Rota, and Dr. Anthony Delgado, a general pediatrician at the Rota pediatric clinic. The district court found Dr. Shales’ diagnosis unreliable.

. Sosa recognized that Congress’ intent in enacting the foreign country exception was to prevent the United States from being subjected to liability under the laws of a foreign power. See 542 U.S. at 707 , 124 S.Ct. 2739 . However, the Court also acknowledged that under its interpretation of the statute, the foreign country exception would apply even "when a State’s choice-of-law approach would not apply the foreign law of place of injury.” Id. at 711 , 124 S.Ct. 2739 . In rejecting a more selective approach, the Court noted that Congress did not write the statutory language to bar claims only "when foreign law would be applied” but rather to bar all claims "arising in” a foreign country. Id. The Court further reasoned that even if such a meaning could be inferred from the language of the statute, it would result in “a scheme of federal jurisdiction that would vary from State to State, benefiting or penalizing plaintiffs accordingly.” Id. Thus, a consequence of the Court’s decision in Sosa is that the foreign country exception will sometimes bar suits that would not have triggered the application of foreign law.

. It is for this same reason that we reject any suggestion that the Holts' administrative claim, which lists "cerebral palsy” as an injury caused by the USAF’s negligence, establishes that S.H. had cerebral palsy in Spain. Where an injury is suffered for the purposes of the foreign country exception is an objective inquiry, one that does not depend on what the Holts knew at a particular time.

. We recognize that courts have sometimes interpreted lex loci delicti to different effect in the context of long-latency diseases. See, e.g., Pounders v. Enserch E&C, Inc., 232 Ariz. 352 , 306 P.3d 9, 13 (2013) (noting that "[flor long-latency diseases, the last event’ takes place when the disease is discoverable because, until then, a legally compensable injury does not exist”); Trahan v. E.R. Squibb & Sons, Inc., 567 F.Supp. 505, 507-08 (M.D. Tenn. 1983) (rejecting argument that "last event” occurred when plaintiff's mother ingested DES, absent any evidence that “improper development of the plaintiff's cervix occurred immediately upon her mother's ingestion of the drug”). But in those cases, there was no evidence that the plaintiffs' exposure to a toxic substance resulted in any immediate harm beyond the cellular level. By comparison, S.H.'s brain injury, resulting from her premature birth, had appreciable effects while the Holts were living in Spain. See In re “Agent Orange” Prod. Liab. Litig., 580 F.Supp. 690, 707 (E.D.N.Y. 1984) (explaining, for purposes of lex loci delicti, that "harmful force” of Agent Orange affected military service members immediately, even though "many of the more serious symptoms did not manifest themselves until years later”).

. The United States raises a number of other issues on appeal; however, our conclusion that the district court lacked jurisdiction obviates the need to address those arguments.
