MEMORANDUM **

Jaime Sandoval, a native and citizen of Mexico, petitions for review of the Board of Immigration Appeals’ (“BIA”) order dismissing his appeal from an immigration judge’s (“IJ”) decision denying his motion to reopen proceedings held in absentia. We have jurisdiction under 8 U.S.C. § 1252. We review for abuse of discretion *567 the denial of a motion to reopen, Celis-Castellano v. Ashcroft, 298 F.3d 888, 890 (9th Cir. 2002), and we review de novo claims of due process violations, Hernandez v. Mukasey, 524 F.3d 1014, 1017 (9th Cir. 2008). We grant the petition for review.

The agency abused its discretion by applying a “strong presumption of effective service” where the record lacks proof of an “attempted delivery and notification of certified mail.” Arrieta v. INS, 117 F.3d 429, 431 (9th Cir. 1997).

The agency also abused its discretion in denying Sandoval’s motion on the ground that Sandoval provided no evidence to corroborate his affidavit alleging non-receipt, where the motion included a corroborating letter from Sandoval’s former employer. See id. at 432 (“when an alien is seeking to reopen deportation proceedings on the ground of lack of notice of the deportation hearing, the Grijalva presumption requires the IJ and BIA to consider the evidence submitted by an alien which supports the defense of nondelivery or improper delivery of the notice”). It follows that the BIA abused its discretion in denying Sandoval’s motion to remand for an evidentiary hearing on the same grounds.

Accordingly, we remand to the BIA with the instruction to remand for further proceedings before the IJ in accordance with this disposition.

In light of our decision, we need not reach Sandoval’s remaining contentions.

PETITION FOR REVIEW GRANTED.
