    Before LUCERO, GORSUCH, and McHUGH, Circuit Judges.
   ORDER AND JUDGMENT

NEIL M. GORSUCH, Circuit Judge.

Mario Ramos-Hernandez is a native and citizen of Guatemala who entered the United States illegally in 2014. In an effort to avoid removal, he applied for relief under 8 U.S.C. § 1231(b)(3) and the Convention Against Torture. An immigration judge and later the BIA denied Mr. Ramos-Hernandez’s application because (among other things) they found his account of past persecution in Guatemala not credible.

Mr. Ramos-Hernandez seeks relief from this ruling, arguing that we should find it wanting for two reasons: (1) he never received an adequate opportunity to explain the inconsistencies in his testimony; and (2) the ruling, is premised on a factual mistake.

This court is precluded by law from considering the first argument. Before bringing an argument to court, an alien seeking relief under the immigration laws must first “present the same specific legal theory to the BIA.” Garcia-Carbajal v. Holder, 625 F.3d 1233, 1237 (10th Cir.2010). This Mr. Ramos-Hernandez failed to do with respect to his first theory for relief.

Mr. Ramos-Hernandez did exhaust his second argument so we may proceed to consider its merits. Before the immigration judge Mr. Ramos-Hernandez claimed that he would be persecuted if returned to Guatemala because of his past participation in demonstrations against the policies of government agencies responsible for energy distribution. The immigration judge found this claim not credible because Mr. Ramos-Hernandez was himself “employed by government-funded electrical agencies” in Guatemala at the time of his past activism. Before this court, Mr. Ramos-Hernandez contends that this credibility determination is legally unsustainable because it was premised on a factual mistake: Mr. Ramos-Hernandez worked for private companies, not a “government-funded agency.” And it’s certainly true that to be sustained credibility findings “may not be based on speculation, conjecture, or unsupported personal opinion ... [but] must be supported by substantial evidence in the record.” Uanreroro v. Gonzales, 443 F.3d 1197, 1205 (10th Cir. 2006) (internal quotation mark omitted). The problem Mr. Ramos-Hernandez faces is that, according to his own testimony, the companies for whom he worked were “hired by” and “vertically integrated” with and operated “under the purview of’ the government. And given this testimony, it’s difficult to see how the immigration judge’s factual finding about the nature of his former employer might be characterized as based on speculation or conjecture rather than substantial record evidence.

Having found the adverse credibility determination in this case sustainable, and given that this determination by itself supplies a legally sufficient basis to support the BIA’s decision, the petition for review is denied. 
      
       After examining the briefs and appellate record, this panel has determined unanimously to honor the parties' request for a decision on the briefs without oral argument. See Fed. R.App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore submitted without oral argument. This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R.App. P. 32.1 and 10th Cir. R. 32.1.
