The Republican Party of Virginia is validating petitions submitted by GOP presidential candidates Newt Gingrich, Mitt Romney, Ron Paul and Rick Perry.
Party spokesman Garren Shipley says petitions from the four candidates were submitted to the State Board of Elections by by Thursday's 5 p.m. deadline.
The validation process began Friday morning, and Shipley says it could continue past midnight. All four candidates are all expected to make the ballot, while Michele Bachmann, Jon Huntsman and Rick Santorum did not qualify to be on the ballot for the March 6 primary.
The party said on Twitter that lots of volunteers showed up at GOP headquarters in Richmond to verify signatures.
Candidates in the March 6 presidential primary must have the signatures of 10,000 registered voters across the state, including at least 400 from each of Virginia's 11 congressional districts.
