LEONARDO TAPIA-FELIX,

 v.

JEFFERSON B. SESSIONS III, Attorney
General,
           Respondent-Appellee.

                    On Petition for Review of an Order of the
                         Board of Immigration Appeals
                                      and
                   Appeal from the United States District Court
                            for the District of Arizona

                     Argued and Submitted October 11, 2018*

             This disposition is not appropriate for publication and is not precedent
except as provided by Ninth Circuit Rule 36-3.
Before: SCHROEDER and NGUYEN, Circuit Judges, and SIMON,** District
Judge.

      Leonardo Tapia-Felix previously petitioned for review of the Board of

Immigration Appeals’ decision upholding his final order of removal from the

United States. We stayed that matter and transferred Tapia-Felix’s claim that he is

a United States citizen by birth to the district court for de novo review. Tapia-Felix

now appeals the district court’s adverse ruling on his citizenship claim, and we

consolidated his two appeals on July 27, 2017. We have jurisdiction under 8

U.S.C. § 1252(b) and 28 U.S.C. § 1291. We vacate and remand.

      The district court correctly found—and the government concedes—that the

government bears the burden of proving by clear and convincing evidence Tapia-

Felix’s alienage.1 See Mondaca-Vega v. Lynch, 808 F.3d 413, 419–20 (9th Cir.

2015) (en banc), cert. denied, 137 S. Ct. 36 (2016) (applying a burden-shifting

framework in which the government presents evidence of alienage, the petitioner

responds with substantial credible evidence of citizenship, and then the burden

shifts back to the government to prove alienage by clear and convincing evidence).



      **
             The Honorable Michael H. Simon, United States District Judge for the
District of Oregon, sitting by designation.
      1
             The parties agree that under Mondaca-Vega’s burden-shifting
framework, Tapia-Felix met his burden at step two of the analysis of showing
substantial credible evidence of citizenship, which then shifted the burden back to
the government to prove his alienage.

                                          2
      This case centers on dueling authenticated birth certificates: one issued in

1972 in Mexico near the time of Tapia-Felix’s birth showing that he was born in

Sonora, Mexico, and the other issued in 1990 in California showing that he was

born in Santa Ana, California.

      In concluding that the government met its burden of showing by clear and

convincing evidence that Tapia-Felix is a Mexican national, the district court stated

that “at the heart of [its] conclusion is [Tapia-Felix’s] authenticated Mexican

registration of birth.” The district court, however, rejected Tapia-Felix’s

California delayed registration of birth. As the district court stated, “the strength

of the [birth] record depends on the evidence relied on by the state officials who

issued it.” The district court found that California officials relied on a baptismal

certificate showing that Tapia-Felix was baptized “on December 17, 1972, at the

Our Lady Queen of Angels Church in in [sic] Los Angeles, California.” The

district court reasoned that because the baptismal certificate was unreliable, no

“credible documentary evidence issued in close proximity to the time of

Petitioner’s birth” “detract[ed] from the evidentiary value of [Tapia-Felix’s]

Mexican birth certificate.”

      The parties, however, had stipulated to the fact of Tapia-Felix’s baptism.

Without notice or an adequate opportunity to respond, the district court rejected

this stipulation. We hold that the district court erred in doing so. Factual


                                           3
stipulations, unlike legal stipulations, are ordinarily binding on courts and “are

‘formal concessions . . . that have the effect of withdrawing a fact from issue and

dispensing wholly with the need for proof of the fact.’” Christian Legal Soc’y

Chapter of the Univ. of Cal., Hastings Coll. of the Law v. Martinez, 561 U.S. 661,

676–78 (2010) (quoting 2 K. Broun, McCormick on Evidence § 254, p. 181 (6th

ed. 2006); accord Dexter v. Kirschner, 984 F.2d 979, 984–85 (9th Cir. 1992), as

amended on denial of reh’g and reh’g en banc (Jan. 29, 1993); see also D. Ariz.

L.R. 83.7 (2016–17) (stating that written or oral stipulations given in open court

are binding, except that “in the interests of justice the Court shall have the

discretion to reject any such agreement”). Thus, at a minimum, the district court

must notify the parties and provide them with a reasonable opportunity to respond

before rejecting a factual stipulation. Because the district court’s rejection of the

stipulation appears to play a central role in its rejection of Tapia-Felix’s California

birth certificate, we cannot say the error was harmless.

      The district court also erred in rejecting parts of expert witness Gretchen

Kuhner’s testimony. Ms. Kuhner testified to a census study commissioned by the

Mexican government in order to better understand transnational families’ practice

of dual birth registration in the United States and Mexico. The study revealed that

nearly half of 550,000 transnational families registered U.S.-born children in

Mexico. In finding this testimony inadmissible, the district court relied on United


                                           4
States v. Bahena-Cardenas, 411 F.3d 1067 (9th Cir. 2005), which is easily

distinguishable. Because Bahena-Cardenas relied on a small sample size (5 or 6

out of 56 people), we found that the district court did not abuse its discretion in

rejecting such testimony because it would “encourage or require jurors to rely on

cultural stereotypes.” Id. at 1078. In contrast, Ms. Kuhner offered a sample size of

over half-a-million people in a formal study commissioned by the Mexican

government. The district court therefore abused its discretion in finding her

opinion inadmissible.

      Finally, Tapia-Felix challenges the district court’s credibility findings for

numerous witnesses. Although we do not find these evaluations to be clearly

erroneous, the district court is free to revisit them on remand. In light of the

district court’s errors with respect to the parties’ stipulation and the expert

witness’s testimony, we vacate and remand for the district court to reevaluate

whether the government has carried its burden of showing by clear and convincing

evidence that Tapia-Felix was born in Mexico.

      VACATED AND REMANDED.
