Iran Press/ America: Hunter Biden, 52, has been under investigation since 2018 and has denied any wrongdoing.
FBI agents are said to have a "viable case" against the son of the US president which they believe will lead to a likely conviction at trial, according to the Washington Post.
Now Delaware US Attorney General, David Weiss - appointed during the Trump administration - must decide whether to file the charges.
The US Department of Justice (DOJ), the FBI and a spokesperson for Weiss have all declined to comment on the case.
Biden's lawyer, Chris Clark, has accused investigators of leaking information about the alleged offences and urged the DOJ to "diligently investigate and prosecute" anyone responsible.
Clark said prosecutors were "diligently and thoroughly weighing evidence" provided by agents and witnesses, including those for the defence - and called for them not to be "pressured, rushed or criticised" while doing their job.
