MEMORANDUM **

Wilberto Trinidad-Ramon, and his wife Angela Ramon-Uscanga, natives and citizens of Mexico, petition for review of the Board of Immigration Appeals (“BIA”) summary affirmance of an Immigration Judge’s decision denying their application for cancellation of removal. We have jurisdiction pursuant to 8 U.S.C. § 1252 . We review de novo the determination of statutorily ineligibility. Montero-Martinez v. Ashcroft, 277 F.3d 1137, 1145 (9th Cir.2002). We grant the petition.

Petitioners were served with their notice to appear in October 1998. Petitioners testified that they arrived in the United States in 1986, but could not produce any documentation of their presence in the United States until the birth of their son in September 1989, despite testifying that they worked during this period and Mrs. Uscanga received prenatal care.

The IJ’s finding that petitioners were statutorily ineligible for cancellation of removal for failure to satisfy their burden of proving ten years of continuous presence in the United States improperly relied on this absence of documentation, see Katana v. INS, 232 F.3d 1107, 1113-14 (9th Cir.2000), and the IJ’s adverse credibility determination appears to be based on conjecture which “cannot be substituted for objective and substantial evidence.” Bandan v. INS, 227 F.3d 1160, 1167 (9th Cir.2000). Further, the IJ ignored Petitioners’ explanations for the perceived discrepancies. See Garrovillas v. INS, 156 F.3d 1010, 1013-14 (9th Cir.1998). Because the IJ’s adverse credibility finding is not supported by substantial evidence, we deem Petitioners’ testimony credible. See Salaam v. INS, 229 F.3d 1234, 1239 (9th Cir.2000).

PETITION FOR REVIEW GRANTED; REMANDED.
