The BIA’s decision indicates that it considered all of the evidence included with Zhu’s third motion to reopen, including a letter from his wife. Contrary to Zhu’s assertions, the BIA did not abuse its discretion in finding the unsworn, uncorroborated letter unpersuasive and entitled to limited evidentiary weight in light of a prior finding that Zhu was not a credible witness.
