Gaitrie Latchman pleaded guilty to one count of conspiracy to commit immigration fraud, in violation of 18 U.S.C. §§ 1028(a), 1543, 1546(a), and 371, and one count of falsely obtaining naturalization and United States citizenship, in violation of 18 U.S.C. § 1425(b) and 8 U.S.C. § 1451. She appeals her conviction only on the falsely obtaining United States citizenship count, contending that during her Rule 11 plea colloquy the magistrate judge failed to establish the factual basis for her guilty plea on that count. She argues that, even though she did not object to the magistrate judge’s report and recommendation, the district court erred by accepting her plea. She also contends that the district court abused its discretion by denying her motion to withdraw her guilty plea, which was based on arguments about the insufficiency of the factual basis for the plea.

I.

In evaluating a defendant’s challenge to the factual basis for her guilty plea, we consider whether the district court “was presented with evidence from which it could reasonably find that the defendant was guilty.” United States v. Frye, 402 F.3d 1123, 1128 (11th Cir. 2005). If a defendant pleads guilty before a magistrate judge and fails to object to his recommendation that the plea be accepted, however, she waives any challenge to the plea proceeding. Fed.R.Crim.P. 59(b)(2) (“Failure to object in accordance with this rule waives a party’s right to review.”); see also United States v. Garcia-Sandobal, 703 F.3d 1278, 1283 (11th Cir. 2013) (holding that a defendant had “waived his right to appellate review” on an issue because he failed to file a timely objection to the magistrate judge’s report and recommendation). The magistrate judge is required to notify the defendant of the right to object and the consequence of failing to do so, but a written notification is sufficient. Nettles v. Wainwright, 677 F.2d 404, 408 (5th Cir. Unit B 1982). 1

Latchman waived her challenge to the district court’s acceptance of the factual basis for her guilty plea because she failed to file a timely objection to the magistrate judge’s report and recommendation. Latchman’s plea colloquy was conducted on October 14, 2011. Two days later, on October 16, the magistrate judge issued a report recommending that the district court accept Latchman’s plea. That report included a notice that failure to object to it within fourteen days would bar any challenge to it before the district court judge. On November 1, 2011, the district court took the magistrate judge’s recommendation and accepted Latchman’s guilty plea, observing that there had been no objection to that recommendation. Because she failed to object to the magistrate judge’s recommendation, she waived her challenge, even for plain error, to the district court’s acceptance of that recommendation. See Fed.R.Crim.P. 59(b)(2); Garcia-Sandobal, 703 F.3d at 1282-83.

II.

When a challenge to a district court’s denial of a motion to withdraw a guilty plea is properly preserved, we normally review the denial only for abuse of discretion, see United States v. Izquierdo, *910 448 F.3d 1269, 1276 (11th Cir. 2006), and will not reverse the district court’s judgment “unless the denial was arbitrary or unreasonable.” Id. (quotation marks omitted). The challenge, which Latehman filed two days before her sentence hearing and 127 days after the magistrate judge issued his report and recommendation, was almost certainly untimely. We will assume for purposes of discussion, however, that it was timely made. Even assuming that, Latehman has failed to show that the district court abused its discretion in denying her motion.

The second superseding indictment charged that Latehman violated 18 U.S.C. § 1425(b) on April 24, 2006, when she applied for, procured, and obtained United States citizenship by falsely swearing that she had neither committed a crime for which she had not been arrested nor had provided false information to a United States official while applying for immigration benefits. To obtain a conviction on that charge, the government had to prove that Latehman knowingly procured her United States citizenship without being entitled to it. See 18 U.S.C. § 1425(b).

The plea agreement, which Latehman swore she had read and understood, and the government’s recitation of the offense conduct during the plea colloquy, which she agreed was true, support the allegations in the second superseding indictment that she committed a crime by conspiring to supply false documentation to non-citizens beginning no later than February 2006. They also support the allegation in the indictment that she lied before a United States immigration officer on April 24, 2006 when she swore that she had committed no crime for which she had not been arrested. The crime she had committed but had not been arrested for at that time was the crime of conspiring to supply false documentation to noncitizens. During her plea colloquy, counsel for the government stated that Latehman had applied for United States citizenship and naturalization on April 24, 2006. Latehman testified that government counsel’s statements were true.

In her motion to withdraw her guilty plea, however, Latehman asserted for the first time that the April 24, 2006 date was wrong and that she had actually submitted her naturalization application in August 2005, before the immigration fraud conspiracy began. She asserted that her plea was not knowing and voluntary because she was “operating under a mistake of fact as to the date of the application.” The district court heard argument on that motion at Latchman’s sentence hearing, before it addressed any sentencing issues. 2 The government argued that, exactly as the indictment had alleged, Latehman had sworn before a United States immigration officer on April 24, 2006 that the contents of her naturalization application were correct. The government also pointed out that Latehman had been provided with a copy of her application to review months before her plea colloquy.

Counsel for the government showed the court a copy of that application, establishing that although the application had been submitted earlier, during an interview with an immigration officer on April 24, 2006 Latehman affirmed under oath before the immigration officer that the information in the application was correct. She also *911 swore under oath during the plea colloquy that the government’s factual account of her crime was true, admitting that in her naturalization application she “swore, affirmed and certified under penalty of perjury that the contents [of the application] were true and correct, and that included her assertion when she answered ‘no’ to the question of whether she had ever committed a crime or offense for which she was not arrested which she knew to be false.” The district court denied Latch-man’s motion to withdraw her guilty plea, emphasizing that she had testified under oath before the magistrate judge that the allegations of the false procurement of citizenship count in the indictment “were, in fact, true and that the facts underlying that count of the Indictment as recited in her presence at the time of her plea were also true.”

Despite Latchman’s assertions to the contrary, there was no indication during the plea colloquy or after it that she failed to understand the nature of the charges against her or the terms of her plea agreement. 3 The district court did not abuse its discretion by denying Latchman’s motion to withdraw her guilty plea.

AFFIRMED.
