MEMORANDUM **

Lead petitioner Carlos Julio Sanchez and his family, natives and citizens of Colombia, petition for review of an order of the Board of Immigration Appeals (“BIA”) affirming, without opinion, an immigration judge’s (“IJ”) order denying their application for asylum. We have jurisdiction pursuant to 8 U.S.C. § 1252. Reviewing for substantial evidence, see Ochoa v. Gonzales, 406 F.3d 1166, 1169 (9th Cir. 2005), we deny the petition for review.

Substantial evidence supports the IJ’s determination that Sanchez failed to establish a well-founded fear of persecution on account of a protected ground. Sanchez’s contention that he fears persecution based on his refusal to cooperate with narcotraffickers is without merit. See id. at 1172 (finding “no evidence that the narcotraffickers imputed political beliefs” to petitioner, who resisted pressure by narcotraffickers to participate in a money laundering scheme).

Moreover, even if we were compelled to find that Sanchez had established a nexus to a protected ground, substantial evidence supports the IJ’s determination that Sanchez failed to establish even a ten percent chance of persecution on that basis. As the IJ noted, Sanchez testified that neither he nor his family was harmed by the narco-traffickers and that he had only the impression that the narco-traffickers were threatening him. See Nahrvani v. INS, 399 F.3d 1148, 1153 (9th Cir. 2005) (upholding determination that petitioner’s fear was not well-founded where petitioner was never physically harmed and received only *130anonymous, vague threats that “did not create a sense of immediate physical violence”). As the IJ further noted, Sanchez testified that he returned to Colombia without fear after having received the bulk of the alleged threats and that he didn’t know whether the narco-traffickers who had approached him were still in Colombia some twelve years after his last contact with them. See Rodriguez-Rivera v. INS, 848 F.2d 998, 1006 (9th Cir. 1988) (upholding determination that petitioner had no well-founded fear where he remained in the country undisturbed for two months after being threatened, where the guerrilla who threatened him was dead, and where there was no evidence that other guerrillas continued to be interested in him).

Sanchez’s motion to hold this appeal in abeyance pending the government’s response to Sanchez’s request to join in a motion to reopen is denied.

PETITION FOR REVIEW DENIED.
