There are indications that a recent Nebraska court ruling won't delay the federal regulatory process.
State governors leaving a meeting with President Barack Obama say he told them to expect a final decision within a few months.
And the State Department says the federal process is continuing despite the court ruling.
The court threw out a law that gave the governor the power to force landowners to allow the pipeline to run through their property.
Opponents believe this has stalled Keystone, while a State Department official has conceded that lawyers were examining the ruling to determine what it meant for the process.
