Upon his return to the United States on July, 17, 2012, he had grown a long, thick beard.[46][102][36][43] His life took on an "increasingly puritanical religious tone" with "Islamist certainty."[103] He appeared, to some family members, to become an "extremist.
After he came back, he created a YouTube channel with playlist links to two videos which were tagged under a category labeled "Terrorists", including one to Islamic militant Abu Dujana; the videos were later deleted.[104][105] CNN and the SITE Institute found a screen grab of one of the videos, which featured members of the militant Islamist group Caucasus Emirate from the North Caucasus.[105] He also linked to jihadi videos on a profile attributed to him on the Russian social networking site Vkontakte, including ones by a radical cleric and a Syrian jihadist video posted on April 9, 2013; in one video, voices can be heard singing in Arabic as bombs explode.[96][106][22] He recently also shared videos of lectures from a radical Islamic cleric.[22] He frequently read extremist sites, including al-Qaida's Yemen affiliate's Inspireonline magazine.
At some point he applied for U.S. citizenship but a record of his 2011 FBI interview led Homeland Security to hold up his application.[88]
