Rangers chief executive Charles Green claims the club are working to become a member of the English Football League.
The club, reformed after going into administration last year, have competed in the Scottish Third Division this season, with Green critical of plans to restructure Scottish Football.
Green cited the example of Welsh clubs being allowed to play in England and believes attempts to block a move south of the border would be illegal.
"I would be delighted to be the chief executive of Rangers that took them into the English league," Green told reporters.
"We are going to pursue it. We've sought legal advice. I've had enough indications that Scottish football don't like us and don't want Rangers, so I look at other options.
"I have taken legal counsel, because let's be clear: it is a breach of European competition law to deny Scottish clubs, not just Rangers, the right to play in England. That is against European law.
"I don't believe that the authorities would stand back and try to ignore that position.
"You just try and explain to me why a Welsh club can play in the English league but a Scottish club can't."
