Mr Trump, the presumptive Republican Presidential nominee, and his children were seen leaving the Pence home in Indianapolis.
The businessman is expected to name his vice-presidential pick this week.
Mr Pence endorsed former candidate senator Ted Cruz in May but said he would support whoever is the Republican nominee.
At a rally in Indiana on Tuesday night, Mr Trump said of Mr Pence: "I don't know whether he's going to be your governor or your vice president, who the hell knows?"
Mr Pence joined him onstage and was received warmly by the crowd.
Other potential VP candidates reportedly being considered are former House of Representatives Speaker Newt Gingrich, New Jersey Governor Chris Christie and retired Lieutenant General Michael Flynn.
Mr Trump is to be nominated as the official Republican pick at the Republican National Convention next week.
Also on Wednesday, the Associated Press reported that Mr Trump filed a lawsuit against Sam Nunberg, a former campaign aide.
Mr Trump is seeking $US10 million in damages for alleged breach of confidentiality.
Trump University video release hearing
And a judge is to hear arguments over whether to publicly release video excerpts of Mr Trump being questioned under oath about his Trump University real-estate seminars.
Mr Trump's lawyers are fighting the release of the videos, saying they will be exploited by media organizations and others during the presidential campaign.
Lawyers for students who claim they were misled and defrauded by Trump University argue there is no good reason to block release of the videos because transcripts of the testimony are already public.
The hearing is before US District Judge Gonzalo Curiel in San Diego, who is overseeing two class actions over the Trump University venture.
A separate fraud case by New York state's attorney general is pending.
