OPINION

With the aid of smugglers known as snakeheads, Zai Rong Chen, a native and citizen of China, traveled to the United States in 1994. He was placed in exclusion proceedings under Alien Number, A71 800 179. The Board of Immigration Appeals (“BIA”) affirmed the Immigration Judge’s (“IJ”) denial of Chen’s application for asylum and withholding of removal, in which he alleged persecution under China’s one- *206 child policy. Chen was deported to China in 1995.

In December 2000, Chen attempted to re-enter the United States. He was placed in removal proceedings and assigned a new Alien Number, A77 347 289. Chen applied for asylum, restriction on removal, and withholding under the United Nations Convention Against Torture. The IJ granted relief in November 2001, finding that Chen had suffered past persecution because his wife had been sterilized. But after the government located the record from Chen’s 1994 exclusion proceedings, it moved to reopen, vacate the order granting relief, and terminate the removal proceedings. The IJ granted the motion in January 2002; the BIA affirmed without opinion. Later, however, the parties filed a joint motion to reopen. The BIA granted the motion and remanded the case for consideration of Chen’s second application for relief and any inconsistencies between it and Chen’s 1994 application.

Following an April 2006 hearing, the IJ denied relief, finding that Chen was not credible because of contradictions in his story, hesitancy in testifying, and the deception evident in his effort to reapply for relief under a new Alien Number. The BIA affirmed, stating that the IJ’s adverse credibility determinations were not clearly erroneous, that Chen failed to demonstrate eligibility for relief, and that Chen did not merit relief as a matter of discretion. Chen filed a petition for review of the BIA’s decision.

The BIA’s adverse credibility determinations and findings of fact will be upheld if they are supported by “reasonable, substantial and probative evidence on the record considered as a whole.” Tarrawally v. Ashcroft, 338 F.3d 180, 184 (3d Cir. 2003) (quotations omitted). Adverse credibility determinations based on speculation or conjecture are not upheld. See Gao v. Ashcroft, 299 F.3d 266, 272 (3d Cir. 2002). In general, “minor inconsistencies and minor admissions ... are not an adequate basis for an adverse credibility finding.” Id. Any discrepancies must involve the heart of the claim. Id. Because the BIA agreed with the IJ’s adverse credibility findings and also provided its own rationale, we review both the BIA’s order and the IJ’s decision. 1 See Jarbough v. Att’y Gen., 483 F.3d 184, 191 (3d Cir. 2007).

We do not endorse most of the adverse credibility determinations. For example, the BIA supported its adverse credibility determination in part by relying on the IJ’s description of Chen’s “delay and hesitancy” in testifying. When asked if he had any other problems with the family planning officials, Chen paused before stating that his wife had been arrested and detained for two months. Later, Chen claimed that his wife had been sterilized. The IJ questioned “why it took the respondent so long to remember these incidents.” It is certainly appropriate for an IJ to consider an asylum applicant’s demeanor. See Dia v. Ashcroft, 353 F.3d 228, 252 n. 23 (3d Cir. 2003) (en banc) (recognizing that IJ’s observations of demeanor are entitled to a high degree of deference). But Chen explained that he was nervous and thought he did not need to repeat testimony that he had given during his successful asylum hearing in 2001. 2 Tellingly, once Chen *207 overcame his hesitancy, the details he provided concerning his wife’s sterilization and detention matched almost exactly the description of those incidents that he had provided in 2001. In both instances, Chen alleged that his wife was sterilized on April 23, 1999, after family planning officials threatened to prevent his two children from being entered on the household registry. Moreover, Chen consistently claimed his family adopted a boy in 2000 but could not pay the 20,000 RMB fine imposed by the family planning officials. As a result, Chen’s wife was arrested, detained at the family planning office for two months, and released only after Chen’s elderly mother convinced officials that she could not continue by herself to take care of Chen’s children. Under the circumstances, Chen’s ability to accurately recollect these details during his 2006 testimony overcomes any negative credibility inference derived from the manner in which he testified.

Importantly, however, to the extent Chen relied on his wife’s experiences to support his asylum claim, he is not eligible for relief, even if credible. We recently held that the Immigration and Nationality Act (“INA”) does not extend automatic refugee status to spouses or unmarried partners of individuals who have been forcibly subjected to coercive family planning measures. See Lin-Zheng v. Att’y Gen., 557 F.3d 147 (3d Cir. 2009) (“Thus, there is no room for us to conclude that Congress intended to extend refugee status to anyone other than the individual who has either been forced to submit to an involuntary abortion or sterilization, has been persecuted for failure or refusal to undergo such a procedure, or has a well-founded fear of that occurring in the future.”). Therefore, as a matter of law, the experiences of Chen’s wife cannot establish his eligibility for asylum. 3 And, consequently, the BIA’s discretionary denial of asylum was not manifestly contrary to law or an abuse of discretion. See INA § 242(b)(4)(D) [8 U.S.C. § 1252(b)(4)(D) ].

For the foregoing reasons, we will deny the petition for review. 4
