ON REMAND FROM THE UNITED STATES SUPREME COURT ORDER AND JUDGMENT*

Marcelino Najera-Morales was convicted of illegal reentry following deportation, in violation of 8 U.S.C. §§ 1326(a)(1) and (a)(2). He appealed the district court’s refusal to grant a downward adjustment based on acceptance of responsibility, pursuant to U.S.S.G. § 3E1.1, among other issues. We affirmed. United States v. Najera-Morales, 2004 WL 2445639 (10th Cir. Nov.2, 2004) (unpublished disposition). He filed a petition for writ of certiorari to the Supreme Court seeking resentencing under United States v. Booker, — U.S. *750-, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). The Supreme Court granted the writ, vacated the judgment, and remanded the case to us for further consideration in light of Booker. Najera-Morales v. United States, — U.S. -, 125 S.Ct. 1997, 161 L.Ed.2d 852 (2005). We asked the parties to file supplemental briefs addressing the impact of Booker on this case. We conclude the district court committed plain error in sentencing Mr. Najera-Morales, and we vacate his sentence and remand for resentencing in accordance with Booker.

Background facts and the procedural history of Mr. Najera-Morales’ case are set forth in our previous disposition in this case. We state here only the facts and history now relevant to the sentencing issue before us. Mr, Najera-Morales was convicted after a jury trial of illegal reentry after deportation. The presentence report determined his adjusted offense level was 24, his criminal history was category III, and his guideline range was 63 to 78 months. It recommended that he not receive a two-level downward adjustment for acceptance of responsibility under sentencing guideline § 3E1.1. It noted he had gone to trial and his case was not one of those rare situations that permit the adjustment in such a circumstance, such as to “preserve issues that do not relate to factual guilt” by challenging the constitutionality of a statute or the applicability of a statute to a defendant’s conduct. U.S.S.G. § 3E1.1, cmt. n.2.

Mr. Najera-Morales objected to this recommendation at sentencing. At the time of his arrest, he had admitted he entered the country illegally from Mexico after deportation and without applying for permission. In addition, he presented evidence that prior to his arrest he had taken significant steps to become a citizen, which he believed legally justified his presence in the country. Thus, he had applied to the Immigration and Naturalization Services (INS)1 for permanent residency in early 2001, based on his marriage to a United States citizen, and he received a temporary work authorization. In connection with this process, the INS accepted from him nonrefundable fees totaling over $1400 and met with him over twenty times. It was not until February 2003 that the INS informed him his application was denied because he had previously been deported, and then arrested him.

The district court overruled Mr. NajeraMorales’ objection. It stated that although it believed he had actually accepted responsibility, his circumstances did not fall within the requirement of § 3E1.1. The court sentenced Mr. Najera-Morales at the bottom of the guideline range to 63 months. On appeal, we affirmed the sentence because we similarly concluded that his circumstances were not congruent with the guidelines’ formulation of acceptance of responsibility.

Mr. Najera-Morales did not challenge his sentence below on the ground that it violated his Sixth Amendment right to a jury trial. We therefore review his sentence for plain error. United States v. Gonzalez-Huerta, 403 F.3d 727, 731-32 (10th Cir. 2005) (en banc).2 To establish plain error, Mr. Najera-Morales must *751show that 1) the district court committed error, 2) the error was plain, and 3) it affected his substantial rights. United States v. Cotton, 535 U.S. 625, 631, 122 S.Ct. 1781, 152 L.Ed.2d 860 (2002); Gonzalez-Huerta, 403 F.3d at 732. If the error meets these conditions, we may exercise our discretion to correct the error if it would seriously affect the fairness, integrity, or public reputation of judicial proceedings. Cotton, 535 U.S. at 632, 122 S.Ct. 1781.

The district court committed error in sentencing Mr. Najera-Morales because it treated the guidelines as mandatory, thereby violating the remedial holding of Booker. See United States v. TrujilloTerrazas, 405 F.3d 814, 818 (10th Cir. 2005). Moreover, the district court’s error is now “plain” or “obvious.” Johnson v. United States, 520 U.S. 461, 468, 117 S.Ct. 1544, 137 L.Ed.2d 718 (1997) (holding that “where the law at the time of trial [or sentencing] was settled and clearly contrary to the law at the time of appeal — it is enough that an error be ‘plain’ at the time of appellate consideration”).

In order to demonstrate that the mandatory application of the guidelines affected substantial rights, a defendant must show a “reasonable probability” that the defects in his sentencing altered the result of the proceedings. Trujillo-Terrazas, 405 F.3d at 819 (quoting United States v. Dominguez Benitez, 542 U.S. 74, 124 S.Ct. 2333, 159 L.Ed.2d 157 (2004)). Mr. NajeraMorales can meet this standard “by demonstrating a reasonable probability that had the district court applied a post-Booker advisory sentencing framework, he would have received a lower sentence.” Id. In this case, the district court referred to Mr. Najera-Morales’ dealings with the INS in trying to obtain permanent residency, and stated the following about the acceptance of responsibility adjustment before it pronounced his sentence:

I can ... see that his act isn’t an act of an obstinate man. He just — he has — a man with fifth grade education. It took him a long time to raise the money [in fees to the INS]. He kept paying it---This is unfortunate. This is an awful lot of time, too. But I can — I understand why he wanted to contest — all he really wanted was an opportunity to explain why hé thought it was legal and lawful for him to remain in the United States. I think the legal intricacies is something we can’t expect him to understand. ... I looked at whether it was an argument as to the application of the statute to him, and I don’t see that that fits, either, because of the fact that the issue is his confusion about being permitted to remain in the United States, and that’s not what he was charged with. The charge here is that he again illegally reentered .... He knew he reentered illegally when he did so. I think he thought somehow that was salvaged, or cured by the fact that he was getting these legal permits. I’m sorry that the two of you [defense counsel and defendant] were unable to reach an understanding, and that he was unable to understand how this works, but as a result, then, I don’t believe that it would be appropriate or lawful for him to get acceptance of responsibility. If I could award it, I would, because I think he accepts his responsibility, but given the confines of the acceptance of responsibility case law in the Tenth Circuit, it has to be challenging the Constitutionality of the statute or the applicability of a particular statute to his case. I’ve explained why I don’t believe that that is appropriate.

Rec., vol. 5, at 17-19 (emphasis added).

The district court clearly expressed sympathy for Mr. Najera-Morales, con*752cern over the length of his sentence, and dissatisfaction with the mandatory nature of the guidelines that precluded it from awarding him an adjustment for acceptance of responsibility. As a result, the district court would likely have sentenced Mr. Najera-Morales to a lesser sentence in an advisory guidelines system. See Trujillo-Terrazas, 405 F.3d at 819-20. If the court had granted him the two-level downward adjustment for acceptance of responsibility, his guideline range would have been 51 to 63 months. He likely would have been sentenced to 51 months imprisonment, or more than one year less than his current sentence of 63 months. We decline to deem a one-year difference in a sentence, which constitutes a twenty-five percent increase in the length of imprisonment in this case, insubstantial. Indeed, the government concedes that the district court’s error affected Mr. NajeraMorales’ substantial rights because the court was sympathetic to his circumstances, it would probably have granted him a decrease in sentence, and the error therefore resulted in a one-year increase in his sentence. Aple. Br. at 8-9.

We possess discretion to correct plain error when it affects the integrity, fairness, or public reputation of judicial proceedings. Johnson, 520 U.S. at 467, 117 S.Ct. 1544; Trujillo-Terrazas, 405 F.3d at 820-21. This standard is an “especially demanding” one, requiring a defendant to show an error is “particularly egregious and that failure to correct it would result in a miscarriage of justice.” United States v. Dowlin, 408 F.3d 647, 671 (10th Cir. 2005). Factors that support an exercise of our discretion include: a sentence increased substantially based on a Booker error; a showing that the district court likely would impose a significantly lighter sentence on remand; a substantial lack of evidence to support the entire guidelines sentence imposed; a showing that objective consideration of the 18 U.S.C. § 3553(a) factors warrants a departure; or other evidence peculiar to the defendant that demonstrates a complete breakdown in the sentencing process. See id. at 671.

As discussed above, Mr. Najera-Morales’ sentence was substantially increased based on a Booker error and the record shows the district court likely would impose a significantly lighter sentence on remand. Moreover, the district court believed Mr. Najera-Morales had actually accepted responsibility within the spirit, although not the letter, of § 3E1.1. The purposes of § 3E1.1 include promoting society’s interests in “the reduction of crime ... and the increased potential for rehabilitation among those who feel and show true remorse for their anti-social conduct.” United States v. Henry, 883 F.2d 1010, 1011-12 (11th Cir. 1989) (citation omitted). In stating that it believed Mr. Najera-Morales accepted responsibility, the district court effectively found that Mr. Najera-Morales exhibited sincerity, remorsefulness, and rehabilitation potential equivalent to those exhibited by other defendants who are entitled to the acceptance of responsibility adjustment under § 3E1.1.

The district court’s conclusion has strong support in the record. When Mr. Najera-Morales applied for permanent residency with the INS, he gave the agency his correct name and acknowledged his true place of birth and the fact that he was a Mexican citizen. He also completed all the paperwork and provided all the documents the INS requested, including proof of his marriage, medical records, and fingerprints. When he was arrested, he admitted he had been deported, he had reentered the country illegally, and he had not submitted an application for permission to reenter. At trial, he only contested whether the actions of the INS established that *753the Attorney General had in effect consented to his reentry, and he never claimed that the Attorney General actually informed him he could reenter. The district court found that Mr. Najera-Morales only went to trial because he was understandably confused about the immigration laws, especially in light of his minimal education and the INS’s seemingly welcoming response to his application for permanent residency. Given the very unusual circumstances of Mr. Najera-Morales’ case, the district court’s finding that he deserved an acceptance of responsibility adjustment is entitled to great deference. Trujillo-Terrazas, 405 F.3d at 821. The court was in a unique position to evaluate Mr. Najera-Morales’ acceptance of responsibility. See § 3E1.1 cmt. n.5. It was also best situated to assess his credibility and character.

Objective consideration of the § 3553(a) factors also support the conclusion that Mr. Najera-Morales’ circumstances warrant a downward adjustment. The district court’s findings at sentencing implicate the § 3553(a) factors, including: “characteristics of the defendant,” (a)(1); the need “to protect the public from further crimes of the defendant,” (a)(2)(c); and the “need to avoid unwarranted sentencing disparities among defendants,” (a)(6). The court recognized that Mr. Najera-Morales possesses a fifth-grade education and thus had difficulty understanding the immigration laws. Rec., vol. 5, at 17, 23. At sentencing, the court explained the sentence and its reasoning to him in Spanish:

I understand your explanation. It is a shame that we cannot reduce your time, given your explanation, but it is not possible for me to reduce your time. I understand that you must have been confused because of the actions of the Immigration department. They gave you permission to work, accepted your money, gave you time to come in.... It is very complicated. Many times, people get nervous in court, and you have not had the preparation that many of us have had with regard to going to school for a long time. And these are complicated things, and I don’t blame you for not having understood before, but understand it now.

Id. at 20-21, 23. In addition, the court recognized Mr. Najera-Morales’ family circumstances imposed special hardship on him because he is married to a United States citizen. It advised Mr. NajeraMorales that because he was going to be deported after he served his sentence, he would have to seek to build a new life in Mexico with his wife and family.

Moreover, because the court found that Mi'. Najera-Morales had accepted responsibility, was remorseful, and had rehabilitation potential, factor § 3553(a)(2)(c) is satisfied because of a lack of any showing of need to protect the public from future crimes. When Mr. Najera-Morales informed the court that he accepted responsibility, he further expressed to the court his desire to be sent back to Mexico as soon as possible. After receiving his sentence, Mr. Najera-Morales stated that had he not believed he could make his status legal in the United States, he would not have reentered the country. The dialogue between the court and Mr. Najera-Morales shows that he understands he cannot reenter the United States in the future and that he is not likely to endeavor to do so.

Finally, the very unusual circumstances in Mr. Najera-Morales’ case implicate § 3553(a)(6), which seeks to achieve uniform sentencing of defendants with similar conduct. Trujillo-Terrazas, 405 F.3d at 820. Given the district court’s factual finding that he effectively accepted responsibility, his punishment is not in accord with his conduct. His acceptance of responsibility for his illegal status in the country was within the spirit of § 3E1.1, but he *754was not able to receive consideration under the guidelines commensurate with his candor, cooperation with authorities, and good faith efforts to become legal. Moreover, Mr. Najera-Morales’ actions in seeking to “cure” his illegal reentry by openly approaching the INS, paying the not insubstantial agency fees, and persistently remaining in contact with the authorities, is far from “run of the mill” among defendants faced with similár immigration concerns, and merits special consideration. See id. at 819, 820. In sum, Mr. NajeraMorales presents a “compelling case” for departure under § 3553(a), and to allow the “mismatch between the sentence suggested by the principled application of the post-Booker sentencing framework and the actual sentence given to him would call into question the fairness, integrity, and public reputation of judicial proceedings.” Id. at 821.

For the foregoing reasons, we VACATE the judgment of the district court and REMAND for resentencing. We reinstate our prior disposition, United States v. Najera-Morales, 2004 WL 2445639 (10th Cir. Nov.2, 2004), to the extent that it does not conflict with this opinion.
