The government appeals from the district court's pretrial dismissal of an indictment charging Defendant-Appellee Giovanni Flores with violating 18 U.S.C. § 922(g)(5)(A) by being an alien, illegally or unlawfully in the United States, in possession of a firearm. Because the district court erred in concluding that Flores was not illegally or unlawfully in the United States, we REVERSE and REMAND.

The facts essential to this appeal are undisputed. Giovanni Flores is a native of El Salvador who illegally entered the United States in January 2001. He was not inspected by immigration officials when he entered, and he secured no authorization of any kind to enter the country. Apparently, his illegal entry and unlawful presence in the United States went undetected. In March 2001, the Attorney General designated El Salvador as a country whose citizens may be eligible for "temporary protected status" ("TPS") under 8 U.S.C. § 1254a.1 In May 2001, Flores surfaced and applied for TPS.

An alien whose application for TPS is granted is entitled to certain benefits. See 8 U.S.C. § 1254a (2000). Most importantly, the government "shall not remove the [temporarily protected] alien from the United States during the period in which such status is in effect," and it "shall authorize the alien to engage in employment in the United States and provide the alien with an `employment authorized' endorsement or other appropriate work permit."2 8 U.S.C. § 1254a(a)(1).

An alien who applies for TPS and establishes a prima facie case of eligibility is entitled to "temporary treatment benefits" while his TPS application is pending. See 8 U.S.C. § 1254a(a)(4)(B); 8 C.F.R. § 244.10(a). Temporary treatment benefits consist of two of the benefits available to aliens who actually obtain TPS — namely, non-removability and employment authorization. See 8 U.S.C. § 1254a(a)(1) & (4)(B); 8 C.F.R. § 244.10(e).

After applying for TPS in May 2001 and paying the requisite fees, Flores was issued an employment authorization card and a social security card. Thus, he was deemed to have established a prima facie case for eligibility, and accordingly, he was granted temporary treatment benefits. See 8 C.F.R. § 244.10(e) ("Temporary treatment benefits shall be evidenced by the issuance of an employment authorization document."). Thus, although the government had not granted his application for TPS, Flores acquired a temporary stay of removal pending disposition of his application. See id.; see also 8 U.S.C. § 1254a(a)(1)(A) & (4)(B).

In October 2002, while still awaiting the disposition of his May 2001 application, Flores reapplied for TPS. In November 2002, Flores applied for and received an extension of his work permit. Thus, during the relevant times, Flores maintained temporary treatment benefits. Neither the May 2001 nor the October 2002 TPS application had been ruled upon during the time period relevant to his case.

Flores's employment authorization, together with his social security card and Texas identification card, allowed him to obtain a commission as a private security officer from the Texas Commission on Private Security. He was hired by a private security firm, Bayou City Patrol, and worked as a security guard. As part of his job, he carried a loaded firearm.

On June 8, 2003, as part of an ongoing investigation3 of private security firms employing and arming illegal aliens as security guards in Houston, Texas, Flores was arrested for possession of a firearm while being an alien illegally or unlawfully in the country in violation of 18 U.S.C. § 922(g)(5)(A). On July 8, a grand jury returned an indictment charging Flores with a violation of 18 U.S.C. § 922(g)(5)(A). Flores entered a plea of not guilty on July 13, 2003.

On September 22, Flores filed a motion to dismiss the indictment. He argued that because he had applied for TPS and had secured temporary treatment benefits prior to his arrest, he was not an alien illegally or unlawfully in the United States. The district court agreed and dismissed the indictment. The government now appeals.

A. Dismissal of the Indictment under Rule 12

Initially, the government contends that the district court erred procedurally in dismissing the indictment. We disagree, however, because the district court based its disposition entirely on its resolution of a legal question and the facts are undisputed. Both Flores and the government agree that Flores initially entered the country illegally. Both parties agree that prior to his arrest, Flores applied for TPS and, while his TPS applications were pending, he received an employment authorization card and social security card.4 The sole question in this case, therefore, is a question of law: whether Flores's application for TPS and subsequent receipt of temporary treatment benefits cured his illegal entry into the United States for the purposes of § 922(g)(5)(A).5

In this circuit, "`[t]he propriety of granting a motion to dismiss an indictment under [Fed. R.Crim. P.] 12 by pretrial motion is by-and-large contingent upon whether the infirmity in the prosecution is essentially one of law or involves determinations of fact.'" United States v. Korn, 557 F.2d 1089, 1090 (5th Cir.1977) (quoting United States v. Miller, 491 F.2d 638, 647 (5th Cir.1974)). "If a question of law is involved, then consideration of the motion is generally proper."6 Id. (citing United States v. Jones, 542 F.2d 661, 664 (6th Cir.1976)). Thus, the district court did not err by considering the purely legal question at hand in Flores's pretrial motion. See id.; see also United States v. Matassini, 565 F.2d 1297, 1313-14 (5th Cir.1978) (affirming the district court's dismissal of an indictment based on its pretrial resolution of the defendant's complete legal defense that his pardon removed him from the ambit of the felon-in-possession-of-a-firearm statute).

The government relies on a number of cases from other circuits for the proposition that a district court may not look beyond the face of the indictment and rule on the merits of the charges pretrial. See, e.g., United States v. Salman, 378 F.3d 1266, 1267-68 (11th Cir.2004) (per curiam);7 United States v. Jensen, 93 F.3d 667, 669-70 (9th Cir.1996). Regardless of those other courts' conclusions, however, we are bound by our own circuit's precedent and, therefore, find no error in the district court's procedure of resolving a legal question in a pre-trial motion to dismiss the indictment. See, e.g., Korn, 557 F.2d at 1090; Matassini, 565 F.2d at 1313-14; see also Hogue v. Johnson, 131 F.3d 466, 491 (5th Cir.1997) (noting that one panel of this circuit may not overturn another panel absent an intervening decision to the contrary by the Supreme Court or this court en banc).

Moreover, we believe that our approach is correct for a number of reasons. First, in contrast to the Eleventh Circuit's conclusion, dismissing an indictment based on the resolution of a legal question in the presence of undisputed facts is authorized by the FEDERAL RULES OF CRIMINAL PROCEDURE. Rule 12(b)(2) provides that "[a] party may raise by pretrial motion any defense, objection, or request that the court can determine without a trial of the general issue." Fed. R.Crim. P. 12(b)(2). Because a question of law presented in a case involving undisputed facts can be determined without a trial of the general issue, Rule 12 authorized the district court to rule on Flores's motion to dismiss in this instance. This conclusion is supported by the Supreme Court's opinion in United States v. Covington, 395 U.S. 57, 60-61, 89 S. Ct. 1559, 23 L. Ed. 2d 94 (1969). In Covington, the defendant filed a pretrial motion to dismiss the indictment on the ground that he had a complete defense in that his Fifth Amendment privilege against incrimination had been violated. The district court granted the motion and dismissed the indictment. The government appealed to the Supreme Court, which rejected the government's contention that the dismissal was improper and affirmed the district court. The Court found that the district court properly ruled on the pretrial motion because it involved an issue of law and not a factual dispute. The Court noted that under Fed.R.Crim.P. 12, a defense is "capable of determination without the trial of the general issue . . . if trial of the facts surrounding the commission of the alleged offense would be of no assistance in determining the validity of the defense." Covington, 395 U.S. at 60, 89 S. Ct. 1559. Finally, our approach avoids the waste of judicial resources that results from "legally meritless cases being sent to trial."8 Salman, 378 F.3d at 1269 (recognizing the disadvantages of prohibiting a district court from making pretrial legal determinations on undisputed facts). Accordingly, the district court did not procedurally err.

The government also argues that the district court erred on the merits because it granted Flores's motion to dismiss the indictment after concluding that Flores was not "illegally or unlawfully in the United States" and thus not in violation of § 922(g)(5)(A). The government claims that Flores's application for TPS and receipt of temporary treatment benefits did not alter Flores's status as an illegal alien for the purposes of § 922(g)(5)(A) and that he was therefore subject to prosecution for possessing a firearm. We agree with the government.

"A challenge to an indictment based on the legal sufficiency of uncontested facts is an issue of law reviewed de novo." United States v. Banks, 339 F.3d 267, 269 (5th Cir.2003) (emphasis omitted). We also analyze questions of statutory interpretation de novo. See United States v. Fitch, 137 F.3d 277, 281 (5th Cir.1998); see also United States v. Atandi, 376 F.3d 1186, 1188 (10th Cir.2004) ("[W]e review de novo the district court's dismissal of the indictment based on its interpretation of the underlying criminal statute.").

Section 922(g)(5)(A) provides: "It shall be unlawful for any person. . . who, being an alien . . . is illegally or unlawfully in the United States . . . [to] possess in or affecting commerce, any firearm or ammunition. . . ." The phrase "illegally or unlawfully in the United States" is not defined by the statute. We must construe undefined statutory terms "in accordance with [their] ordinary and natural meaning, as well as the overall policies and objectives of the statute." United States v. Lowe, 118 F.3d 399, 402 (5th Cir.1997) (internal citations omitted).

We read the phrase "illegally or unlawfully in the United States" in § 922(g)(5)(A) to include those aliens, like Flores, who entered the country illegally and subsequently qualified for temporary treatment benefits under 8 U.S.C. § 1254a. Our interpretation is informed by the administrative regulations promulgated by the ATF interpreting § 922(g)(5)(A). See 27 C.F.R. § 478.11. Those regulations define an "[a]lien illegally or unlawfully in the United States" as an alien who is "not in valid immigrant, nonimmigrant or parole status[;][t]he term includes any alien . . . [w]ho unlawfully entered the United States without inspection and authorization by an immigration officer and who has not been paroled into the United States under section 212(d)(5) of the Immigration and Nationality Act (INA). . . ." See id. Although interpreting 18 U.S.C. § 922(g)(5)(A) poses a question involving a mixture of both immigration and criminal law, Congress delegated authority to implement § 922(g) to the ATF.9 See 18 U.S.C. § 926(a) (authorizing "such rules and regulations as are necessary to carry out the provisions of this chapter"). Thus, without deciding whether full Chevron10 deference is appropriate in this instance, we owe at least some degree of deference to the ATF's interpretive regulation of § 922(g)(5)(A) because it is "both reasonable and consistent with our interpretive norms for criminal statutes." Atandi, 376 F.3d at 1189 (affording "some deference" to the ATF's interpretation of § 922(g)(5)(A)) (citing Babbitt v. Sweet Home Chapter of Cmtys. for a Greater Or., 515 U.S. 687, 703, 115 S. Ct. 2407, 132 L. Ed. 2d 597 (1995)). Under § 478.11, Flores is an alien illegally or unlawfully in the United States because he "unlawfully entered the United States without inspection and authorization by an immigration officer" and because his application for TPS and receipt of temporary treatment benefits did not constitute a "parole[ ] into the United States under section 212(d)(5) of the [INA]." 27 C.F.R. § 478.11; see also 8 U.S.C. § 1182(d)(5)(A); 8 U.S.C. § 1254a.

Flores argues that he was not in the United States illegally or unlawfully once he received temporary treatment benefits because those benefits — namely, a stay of removal and an employment permit — "authorized" him to be in the country. He argues that under United States v. Igbatayo, 764 F.2d 1039 (5th Cir.1985), such authorization shields him from prosecution under § 922(g)(5)(A). Igbatayo, however, stands for no such proposition. There we stated:

[I]t is clear that an alien who is in the United States without authorization is in the country illegally. After failing to maintain the student status required by his visa, Igbatayo was without authorization to remain in this country. He thus was in the same position legally as the alien who wades across the Rio Grande or otherwise enters the United States without permission.

Igbatayo, 764 F.2d at 1040. As Igbatayo explains, an alien without any authorization whatsoever is in the country illegally. That conclusion is obvious. But it does not follow that an alien who has been granted limited temporary authorization (i.e., a temporary stay of removal and a temporary work permit) is in the country legally for all purposes, rendering him immune to prosecution under § 922(g)(5)(A). Rather, consistent with Igbatayo, an alien may be temporarily granted a stay of removal and be permitted to work during that stay, but still be considered "illegally or unlawfully in the United States." See Hussein v. INS, 61 F.3d 377, 381 (5th Cir.1995) (holding that a temporary stay of removal "did not change the alien's previously illegal status into a lawful status"); United States v. Bazargan, 992 F.2d 844, 848-49 (8th Cir.1993) (holding that an alien was illegally in the United States for the purposes of § 922(g)(5)(A) despite his receipt of employment authorization).11 Thus, despite his receipt of temporary treatment benefits pending disposition of his application for TPS, Flores remained illegally or unlawfully in the United States under § 922(g)(5)(A).12

For the foregoing reasons, we REVERSE the judgment of the district court and REMAND for further proceedings not inconsistent with this opinion.
