The 32-year-old defender won the last of his eight caps for Germany in 2010 and has made 255 German league appearances for Wolfsburg, winning the 2009 Bundesliga title and the 2015 German Cup.
His mother lives near Atlanta and he had planned to join an unnamed MLS club once his current Wolfsburg contract expires in June.
But the results of last week's US election has given Schäfer second thoughts over plans to play out his career in the United States after Trump was heavily criticized for sexist and racist comments during his campaign.
"The option is still there, but I am no longer quite so sure any more," he told local newspaper Wolfsburger Allgemeine Zeitung with Trump due to take office on January 20th 2017.
"The outcome of the election has got me thinking.
"When I look at the election campaign, a lot happened which is incompatible with my values, especially because I am an athlete. It makes you pensive."
Should his plans to move to the United States fall through, Schäfer could reportedly join Wolfsburg's backroom staff after his playing career.
