*442OPINION

Xue Long Huang petitions for review of the Board of Immigration Appeals’ decision denying his request for asylum, withholding of removal, and relief under the Convention Against Torture. For the reasons that follow, we will deny the petition.

I. Facts and procedural history Huang, a citizen and native of the People’s Republic of China, entered the United States without proper entry documents in December 2008. At a subsequent removal hearing, Huang admitted removability, but applied for asylum, withholding of removal, and CAT relief, all on the ground that he, as a practitioner of Falun Gong, would be persecuted and tortured if returned the China.

Upon arriving in the United States, Huang was detained and accorded a credible-fear interview. At that interview, he claimed that he began practicing Falun Gong on February 15, 2002. AR 287. According to Huang, a friend of his was coerced into telling the police that Huang practiced the religion, and Huang was arrested while practicing Falun Gong at home on March 22, 2002, by four or five police officers. Id. Huang further claimed that he was detained for nearly a month (until April 16, 2002), and beaten on twenty occasions during his detention. Id. He stated that he was forced to promise never to practice Falun Gong again, and that he would be subject to persecution if returned to China because he would continue practicing the religion. Id.

At his asylum hearing, Huang testified that a friend introduced him to Falun Gong, and that he began practicing it at that friend’s home in September 2001. Id. at 92. A few months later, in January 2002, the friend was arrested for practicing Falun Gong and gave Huang’s name to the police. Id. at 95. The day after (still in January 2002), Huang himself was arrested, interrogated, beaten, and detained for a month. Id. Huang testified that he was only released because his parents agreed to pay the police a handsome sum. Id. at 97. After he was released, Huang found that he was regularly tracked by police agents. Id. To escape a life of constant surveillance, Huang left China in December 2002, and eventually made his way to the United States, arriving nearly a year later. Id. at 98.

Noting the discrepancies between the dates given at the hearing and in the credible-fear interview, the IJ probed Huang for an explanation, but he was unable to provide one. Id. at 122. On cross examination, Huang admitted that he was brought to the United States by professional alien smugglers. Id. at 139. He further admitted that his family had paid the smugglers $66,000 to have him successfully admitted to the United States, and that the money was only payable upon his release from custody. Id. Most importantly, he admitted that the smugglers instructed him to claim to be a persecuted practitioner of Falun Gong. Id. at 141.

The Immigration Judge denied Huang’s application for relief, finding his testimony of his practice of Falun Gong not credible. The BIA affirmed and adopted the IJ’s decision, and Huang now petitions for review.1

II. Standard of review

Because the BIA expressly adopted the IJ’s findings with no substantive addition of its own, we review both decisions. Luciana u Att’y Gen., 502 F.3d 273, 279 (3d Cir. 2007). The sole issue on petition is whether it was permissible for the IJ to discredit Huang’s testimony.2 This is a *443finding of fact, and we, accordingly, review it under the substantial-evidence standard. Xie v. Ashcroft, 359 F.3d 239, 243 (3d Cir. 2004). We may not set aside the IJ’s finding unless “any reasonable adjudicator would be compelled to conclude to the contrary.” 8 U.S.C. § 1252(b)(4)(B).

III. Discussion

As the IJ noted, Huang’s testimony that he was brought to the United States by paid smugglers who told him to claim to practice Falun Gong raises serious questions about Huang’s credibility. As the IJ also noted, Huang’s testimony at the asylum hearing seems internally inconsistent: at one point, he testified that he practiced Falun Gong from early September 2001 until late January 2002 before he was arrested, AR 92-95; at another, he testified that he practiced Falun Gong for a period of 30 days, id. at 124. The IJ found puzzling the different dates Huang offered in his testimony at the asylum hearing and in his responses at his credible-fear interview. To remember such specific dates, yet remember them differently on the two occasions, led the IJ to suspect that the stories were contrived, particularly in light of Huang’s inability to explain the discrepancies.3

Besides these inconsistencies, as the IJ noted, Huang displayed only a limited knowledge of Falun Gong at his asylum hearing, id. at 132-33, and he appears not to have taken an interest in practicing Falun Gong with others here in the United States, id. at 147. Both of these facts legitimately raise questions about his devotion to the practice. Also, though testifying that he lived with an uncle who knew of his devotion to Falun Gong, Huang did not produce any corroborating evidence (e.g., a statement from his uncle), nor did he give any reason why he could not do so. Id. at 126. All of this evidence together forms a sufficient basis for the IJ to disbelieve Huang’s testimony that he is a Falun Gong practitioner.4

IV. Conclusion

The IJ’s adverse credibility finding has sufficient support in the administrative *444record. Therefore, we will deny Huang’s petition for review.
